Fastic vs Simple 2026: Best Fasting App for Beginners โ

Perplexity 
Most beginners stop opening their fasting app long before they stop caring about fasting. The clearest number on this comes from Simple's own user base: a 52-week study of 792,692 Simple users found 16.7% still active at 13 weeks, 6.9% at 26 weeks and 2.1% at 52 weeks (Torres et al., 2022, PMID 36194463). The app you download in week one shapes which side of that curve you land on.
A 2022 narrative review in Nutrients drew on 66 articles published between 2010 and 2021 and reported that intermittent fasting regimens lead to a decrease in weight and have been linked to improvements in dyslipidemia and blood pressure. The same review flags that "patient adherence remains a problem" (Vasim, Majeed and DeBoer, 2022). Our own read, not the paper's finding: an app you keep opening is the cheapest way to fix an adherence problem.
Fastic and Simple are the two apps that dominate the beginner fasting space in 2026. Simple reports 20M+ downloads and 800,000+ active subscribers on its App Store listing; Fastic claims over 30 million users and shows 10M+ downloads on Google Play. Fortune's 2026 round-up names Simple its overall pick and does not include Fastic at all. The two apps solve the same problem through completely different mechanisms.
This comparison breaks down exactly how each app works, where each falls short, and which one to choose based on how your brain stays motivated.

Quick Verdict: Who Should Pick Which App ๐ โ
| Fastic | Simple | |
|---|---|---|
| Best for | Visual learners, calorie + fasting combo | Coaching-first, habit-building learners |
| Free tier | Broad: timer, body status, food scanner, menu scanner, Fasty | Narrow: basic logging, 2 Avo replies/day, 1 photo scan/day |
| Only duration-labelled prices | $14.99 for 1 month, $27.99 for 3 months | None. Simple labels no SKU with a duration |
| Other listed prices | Eight more Fastic Plus SKUs, $12.99 to $79.99, no durations | Pro and Premium SKUs, $14.99 to $59.99, no durations |
| App Store rating | 4.8/5, 246K ratings | 4.7/5, 393K ratings |
| Google Play rating | 4.4/5, 421K reviews | 4.5/5, 137K reviews |
| Fortune 2026 rank | Not listed | #1 Best IF App Overall (4/5) |
| Coaching style | Self-directed + free AI chatbot (Fasty) | Guided AI (Avo) + Premium daily check-ins |
| Refund policy | 14-day Feel Good Guarantee | 30-day for website purchases |
Store ratings checked 7 August 2026. Prices are standard US prices as of mid 2026 and change by region; both vendors run heavy promo pricing, which is why neither store listing agrees with itself.
Pick Fastic if you want a broad free tier, the body status view, badge motivation, calorie tracking alongside fasting, and a refund safety net you can invoke without conditions.
Pick Simple if you want an AI coach that guides your habit-building through daily check-ins and streak tracking, and you are ready to pay from day one, because Simple gates almost all of that behind Premium.
The feeling every beginner knows: which app actually matches how my brain works?
What Makes Fastic Click for Beginners ๐ฌ โ
Fastic was built around one insight: beginners need to see what is happening inside their body to stay curious enough to keep going.
The Body Status screen is Fastic's biggest beginner differentiator. It shows which fasting phase you are in as the timer runs, naming stages like fat burning and ketosis. Fastic does not publish the hour thresholds it uses, so treat the phase labels as motivation rather than as measurement. For someone who has never fasted before, this still turns a difficult time window into a series of visible checkpoints rather than just more waiting.
Fastic pairs this with a badge and streak model. The mechanics are not documented on any Fastic page, so the only account of them is a customer's: an App Store reviewer in 2020 described earning fire badges for completed fasts and "ice" badges, bought with the app's star system, that let you skip a fast. The same reviewer wrote: "Every time I'm tempted to break my fast early I check the app to see what stage of fat burning I'm in and it helps me keep going... This app is basically using psychology to keep you motivated but it definitely helps me." (App Store review, 14 August 2020)
The free tier is where Fastic separates itself, and it is broader than most write-ups admit. Fastic's non-Plus feature block on Google Play carries the fasting timer, a food and calorie tracker, the Fastic Food Scanner, the Restaurant Menu Scanner, the Fastic Score, Body Status, Fasty the AI chatbot, a step counter and a water tracker. Apple's base list matches. The Fastic Score is the composite view, tracking fasting, hydration, sleep, nutrition and activity in one number.
Fastic Plus adds 4,500+ recipes, the Fastic Academy courses, daily and weekly challenges, Fasting Buddies, a Social Media Channel, and enhanced versions of the two scanners the free tier already has.
The Protein Fasting mode leans on Arciero et al., Obesity 2023 (PMID 36575144), which Fastic quotes on its own store listing. Protein pacing there means four evenly spaced meals of 20 to 40 g protein each, not high-protein eating in general. The results are in the science section below.
Fastic's body stage visualization. Each phase becomes a checkpoint, not just more waiting. The hour marks in this illustration are generic; Fastic publishes none of its own.
Fastic carries 246K App Store ratings at 4.8 out of 5 and 421K Google Play reviews at 4.4 out of 5 with 10M+ Android downloads, both checked 7 August 2026. Play lists the developer as Fastic GmbH; Apple still shows the legacy name HealthVida GmbH & Co. KG. The Feel Good Guarantee gives paid members a 14-day full refund with no usage requirements: no fasting plan to follow, no timer use, no weight updates, no results needed. Fastic headlines it as a "14 Days Free Trial", but the mechanism is a refund. You pay first, then ask for the money back.

๐งฉ The 10-second question (coming soon)
What Makes Simple Click for Beginners ๐ค โ
Simple was ranked the #1 Best Intermittent Fasting App Overall by Fortune in 2026 with a 4 out of 5 rating, in a round-up updated 29 July 2026. MedTech Breakthrough named its coach Avo the Best Virtual Health Coach of 2025. Its approach to beginners is fundamentally different from Fastic.
Where Fastic asks "what is your body doing right now?", Simple asks "what habit are you building today?"
Coach Avo, Simple's AI assistant, answers questions and runs daily check-ins and streak tracking. Those check-ins are the accountability layer, and they are Premium features. Simple's free tier is explicit about it: "No Streak Tracking or AVO Check-ins."
Simple's Premium plan covers weight-loss insights, full access to Avo, Avo Vision, structured workout plans, the daily check-ins and streaks, Blinky, the Success Score, smart feedback and an educational library. Habit workbooks are not in it. Simple's own Premium FAQ calls them optional and skippable, and Apple sells them as a separate "Workbooks Bundle" at $29.99. If a review told you workbooks come with Premium, that review is wrong.
Melissa Mitri, MS RD, reviewed Simple for Everyday Health in a piece updated 5 March 2025 and described a nutrition score rating meals 1 to 4 on protein, fiber, saturated fat, sodium and calcium. That scale is gone. Simple's current scoring feature is the Success Score, a composite daily score built from food quality, water, activity, fasting and weigh-ins, and it sits behind Premium. Simple still sells the coaching-without-arithmetic angle in its own words: "No calorie math, just clear, actionable advice on the go."
Simple carries 393K App Store ratings at 4.7 out of 5 and 137K Google Play reviews at 4.5 out of 5, both checked 7 August 2026. The 20M+ downloads figure is Simple's own claim, and the same paragraph puts active subscribers at 800,000+, which is the number most readers assume the 20M means. Apple names the developer AM APPS; Play names Simple.Life Apps Inc, which is also the copyright holder on the Apple page.
Simple publishes no prices. Its help centre says cost "varies based on the regular plans you select" and that the figure appears at checkout. The price section below has what third parties report. There is no standard free trial either: Fortune's tester recorded none, and Simple's FAQ offers only occasional reduced-price introductory periods.
One limitation for beginners
Simple's free tier gives you basic logging of fasts, meals, hydration, weight and activity, but restricts Avo to two replies a day and Avo Vision to one scan a day. That can frustrate new users who have frequent questions in the first week, exactly when coaching support matters most.
Simple's Coach Avo answers fasting questions on demand, and runs daily check-ins for Premium subscribers

โณ Real beginner scenarios
๐งฉ The 10-second question (coming soon)
Feature Face-Off: 7 Key Categories ๐ โ
Fasting Timer and Window Tracking โ
Both apps offer fasting timers. Fastic's timer integrates with the Body Status view, showing which fasting phase you are in. Simple's timer is cleaner and minimal, paired with Avo check-ins for Premium subscribers at key moments in the fast.
Edge: Fastic for visual motivation; Simple for coaching-led structure.
AI Coaching and Support โ
Fastic includes Fasty, an AI chatbot both stores list in Fastic's free feature block, which answers fasting and nutrition questions on demand. It does not build personalized habit sequences over time.
Simple's Avo AI is the main differentiator. Avo runs daily check-ins, streak tracking and ongoing coaching dialogue designed to build daily consistency. Avo Vision reads photos of groceries, menus and plated meals and returns nutrition guidance and recipe ideas.
The catch on both sides is the same: neither vendor gives away much AI. Fastic's Plus tier reserves the enhanced scanners, and Simple's free tier caps Avo at two replies and one scan a day.
Edge: Simple for structured, sequential coaching depth, once you are paying.
Food Tracking and Calorie Awareness โ
Fastic's free block already includes a food and calorie tracker, the Fastic Food Scanner and the Restaurant Menu Scanner, which photographs a menu and suggests dishes matching your dietary preferences. Plus adds an enhanced version of both scanners. Fastic is the more developed of the two for beginners who want calorie awareness alongside fasting.
Simple logs food, water, activity and weight, and rolls the food-quality part into its Premium Success Score rather than into calorie totals. It is less focused on precise numbers and more focused on food quality patterns over time.
Edge: Fastic for calorie precision; Simple for meal quality coaching.
Fasting Protocol Variety โ
Neither vendor publishes a protocol library. Fastic states no count and names no window ratios on either store listing; the only named protocol on its listings is Protein Fasting. Simple assigns an initial schedule from your onboarding answers rather than offering a library of named protocols, and its current App Store feature list does not mention fasting at all.
Edge: None. This is the one category where both apps ask you to take the fasting schedule on trust.
Community and Social Features โ
Fastic Plus includes Fasting Buddies and a Social Media Channel, listed alongside daily and weekly challenges. The Social Media Channel is a broadcast channel rather than two-way chat, and Fastic's in-app chat is Fasty, so there is no user-to-user messaging on either side.
Simple advertises no community or buddy feature on its plan page or its store listing.
Edge: Fastic for community accountability, on a thin margin.
Free Tier Depth โ
Fastic's free block covers the fasting timer, Body Status, the food and calorie tracker, both scanners, the Fastic Score, Fasty, a step counter and a water tracker. A beginner can use it meaningfully for weeks without paying.
Simple's free tier covers basic logging of fasts, meals, hydration, weight and activity, two Avo replies a day and one Avo Vision scan a day, with no streak tracking and no Success Score.
Edge: Fastic, and it is the widest gap in this comparison.
Refund and Trial Terms โ
Fastic's Feel Good Guarantee gives paid members a 14-day full refund with no usage conditions, and Fastic runs a separate statutory 14-day withdrawal period alongside it. Fastic calls the guarantee voluntary, so read it as a waiver rather than an entitlement. Simple offers a 30-day refund on website purchases, with app store purchases sent to Apple and Google. Simple's commitment subscriptions carve themselves out: no mid-term cancellation except within 7 days, and a non-refundable $29.99 fee otherwise.
Edge: Fastic for the shorter path to your money back.

Real Beginner Scenarios: 3 People, 3 Outcomes ๐ โ
Scenario 1: The visual thinker who needs to "see" progress โ
Maya, a 31-year-old nurse working irregular shifts, tried and quit three fasting apps in six months. She always knew she should fast but found herself breaking the window because "nothing felt real about it." When she switched to Fastic, the body stage display changed her habit. Seeing her body in active fat metabolism at hour 14 made stopping feel like abandoning something real. She completed her first consistent month of 16:8 in week five.
Fastic's visual body stage system is built for Maya's profile. Beginners who respond to data, phase displays, progress calendars, and visual cues tend to stay with Fastic longer than with simpler timer-only apps.
Scenario 2: The anxious starter who needs coaching to feel safe โ
Daniel, 27, was new to fasting and genuinely worried about doing it wrong. He wanted someone to answer his questions rather than just track his hours. Simple's Avo AI answered questions like "what can I drink during my fasting window?" and "is it normal to feel tired on day two?" in real time. He hit the two-reply free cap on day one and paid for Premium in the first week, which is where the daily check-ins live. By week three, he was confident enough to adjust his own window without consulting the app for every decision.
Simple's coaching model is built for Daniel's profile. Beginners who have many questions, feel uncertain about fasting science, or want structured guidance tend to stay with Simple longer than with apps that leave them to self-direct.
Scenario 3: The budget-conscious beginner who wants proof before paying โ
Priya, 24, was not ready to spend money before knowing whether fasting would fit her lifestyle. Fastic's free tier let her use the fasting timer, Body Status, both scanners, the step counter and the water tracker for three weeks before she upgraded to Fastic Plus for the recipe library and academy courses.
Simple's free tier limits Avo to two replies a day and Avo Vision to one scan a day, and withholds streak tracking and the Success Score entirely. A beginner with daily questions in the first week will hit those limits and face pressure to upgrade earlier than they might want to.

โจ The 10-second question (about to reveal)
The 10-Second Question That Picks Your App ๐ฏ โ
You have been patient. Here is what this entire comparison was building toward.
Every beginner who picks the wrong fasting app has one thing in common: they chose based on app store screenshots, not based on how their own motivation actually works.
The research does not settle this for you. Vasim, Majeed and DeBoer's 2022 review names adherence as an open problem rather than a solved variable, and it runs no comparison between one fasting protocol and another (Vasim et al., 2022). What is measured is the drop-off: 6.9% of Simple's users were still active at 26 weeks (Torres et al., 2022). App design is one of the few levers you control on that number, and the wrong design for how you stay motivated does not pull it at all.
Ask yourself one question:
"What made me lose motivation with a health app or habit in the past?"
If your answer is: nothing kept my attention after the first few days - you need external stimulation to stay curious. You need to see progress happening in real time. You are a visual learner who responds to gamification and phase-tracking. Pick Fastic.
If your answer is: I had no one to help me when I got confused or struggled - you need guidance, not just tracking. You need someone to answer your questions and give you a concrete next step each day. Pick Simple.
That is it. One question. Ten seconds. The rest of the comparison is context that supports whichever answer you already knew was true.
For true beginners who cannot yet answer that question
If you have never tried a health app seriously, start with Fastic's free tier. You get a real, useful experience for free and can decide after two weeks whether to upgrade or switch to Simple.

7 Tips for Beginners Starting Intermittent Fasting ๐ก โ
Start with a 10-hour eating window, not an 8-hour one. A gentler start is easier to hold in the first two weeks. Step down to a longer fast once the habit holds rather than starting at the hardest setting.
Keep your eating window at the same times each day. A window that slides by two or three hours a day is a different habit every day. Fix the clock times first, then worry about the length.
Track hydration during your fast. Hunger and thirst produce similar physical sensations in the first days of fasting. Both Fastic and Simple include water tracking for exactly this reason.
Log what you eat during the eating window, even roughly. A fasting timer records when you ate, not what. Both apps ship food tracking for that reason, and a rough log tells you more about a stalled week than the timer ever will.
Break your fast with protein and fiber first. Opening the eating window with high-carbohydrate or very large meals is a common beginner error. Protein and fiber first stabilizes appetite and supports the metabolic benefits of the fasting window.
Expect some fatigue in week one. Tiredness in the first days is common while your eating pattern changes. If it persists or worsens, that is a question for your doctor, not for an app's chatbot.
Open the app every day for the first 30 days, even when you do not fast. Habit formation happens in daily contact with the tool before physical results appear. Both Fastic and Simple are designed to reward daily app opens - use that structure intentionally.
Price Breakdown: What You Pay in Year One ๐ฐ โ
Neither app will tell you what year one costs. Fastic's App Store listing showed ten concurrent Fastic Plus SKUs on 7 August 2026, and only two say how long they last. Simple's shows nine subscription SKUs across two tier names, plus a separate Workbooks Bundle, and labels none of them with a duration, while its help centre says "the exact prices are displayed at the time of purchase". That many live SKUs at once is what heavy promo pricing looks like from the outside.
Figure 1: Cost per month for every plan whose duration a source actually states. The two Fastic bars come from Apple, and $9.33 is $27.99 divided by three. Simple publishes no price of its own, so all three Simple bars are third-party reports, and the two Everyday Health figures are 17 months old. Everyday Health gives the Simple annual plan as "under $5/mo", so that bar is drawn at its $5 ceiling and the real figure sits below it.
Prices are standard US prices as of mid 2026 and change by region.
| Plan | Fastic | Simple |
|---|---|---|
| Free forever | Timer, Body Status, both scanners, Fastic Score, Fasty, step + water tracker | Basic logging, 2 Avo replies/day, 1 Avo Vision scan/day |
| Prices with a stated duration | $14.99 for 1 month, $27.99 for 3 months | None published |
| Other listed SKUs | Eight more, $12.99 to $79.99, no duration shown | Pro and Premium, $14.99 to $59.99, no duration shown |
| Third-party price reports | Not applicable | Fortune 2026: $29.99/mo. Everyday Health, March 2025: $15/mo, $9.99/mo on 3 months, under $5/mo annual |
| Refund window | 14-day Feel Good Guarantee | 30-day on website purchases, $29.99 fee on early commitment cancellation |
| Free trial | None. Pay first, refund within 14 days | None advertised |
Neither app can be called the cheaper one on published figures, because only one of them publishes any. What Fastic offers a hesitant beginner is a broader free tier and a refund with no conditions attached.
What the Science Says About Fasting for Beginners ๐ฌ โ
Vasim, Majeed and DeBoer's 2022 review in Nutrients is a narrative review, not a systematic one. It draws on 66 articles published between 2010 and 2021 and concludes that intermittent fasting regimens "overall lead to a decrease in weight and have been linked to improvements in dyslipidemia and blood pressure", while adding that "patient adherence remains a problem" (Vasim et al., 2022). It does not rank one protocol against another, and it sets no adherence threshold.
The trial behind Fastic's Protein Fasting mode is Arciero et al., Obesity 2023 (PMID 36575144). It compared intermittent fasting with protein pacing against a heart-healthy calorie-restriction diet, matched for energy intake and physical activity expenditure. The fasting arm lost more weight (9% against 5%), more total fat (16% against 9%) and considerably more visceral fat (33% against 14%). One co-author is affiliated with Isagenix International LLC, disclosed on the paper. For beginners worried about losing muscle alongside fat, the fat-free mass result (6% against 3%) is the line that matters.
Both apps attack the drop-off from different angles. Fastic uses phase visuals and badges to make finishing a window feel like completing something. Simple uses Avo's check-ins and streaks to build structure around the fast rather than relying on willpower. Neither vendor publishes retention data of its own, and the only public figure in this category, Torres et al.'s 2.1% at 52 weeks, comes from Simple's user base.
For beginners, the right choice is the app that makes you more likely to open it on day eight after a bad day seven. That is the only metric that matters in the first month.
Who Should NOT Use These Apps โ ๏ธ โ
Fastic may not suit you if
- You dislike badges, streaks, and gamification - the psychology does not work for everyone.
- You want deep personalized AI coaching rather than self-directed visual tracking.
- You eat at irregular times and find calorie tracking burdensome rather than useful.
Simple may not suit you if
- You want a meaningful free experience before paying.
- You want community features and social fasting accountability.
- You want a food scanner, restaurant menu analysis, or detailed macro tracking alongside fasting.
- Your budget is tight and you need to know the price before you commit. Simple publishes none.
- You are in the first week of fasting and need frequent AI coaching. The free tier's two-reply limit will not cover daily questions.
Who should consult a doctor before starting any fast
Talk to your doctor first if you have diabetes (type 1 or 2), are pregnant or breastfeeding, have a history of eating disorders, take medications that require food timing, or have kidney, liver, or heart conditions.
Track What You Eat During Your Eating Window ๐ฑ โ
Both Fastic and Simple include food tracking for the eating window, but neither is optimized for mixed dishes, home-cooked meals, or foods that are difficult to identify from a barcode.
If you cook at home, eat mixed cuisine, or share meals that do not come with nutrition labels, the NutriScan meal scanner fills that gap alongside either fasting app. NutriScan's free plan gives you five scans a week, plus micronutrients and a NutriScore on every meal, four Monika voice calls a week and its own fasting timer. Five scans a week is enough to test the scanner on the meals a food database usually gets wrong: your curries, your restaurant plates, your mixed bowls.
For understanding your personal calorie and macro targets while fasting, the NutriScan macro calculator calculates your maintenance, cut, and surplus targets based on your weight, height, activity, and goal.
5-Step Guide: How to Pick Your First Fasting App โ
Step 1: Check your budget for month one. If you want to test fasting free before paying, Fastic gives you a meaningful free experience. Neither vendor publishes an annual price, so open your own app store and read the figure it shows you at checkout before you decide.
Step 2: Identify your motivation style. Do you respond better to visual goals, meaning badges, the body status view and streak calendars, or to guided prompts, meaning daily check-ins and coaching questions? Fastic is built for visual motivation. Simple is built for coached motivation.
Step 3: Decide whether calorie tracking matters to you. If you want to monitor calories alongside fasting, Fastic integrates that more completely and does it on the free tier. If you only want food quality guidance without the arithmetic, Simple's Success Score approach may suit you better, though it is a Premium feature.
Step 4: Check whether community features matter. Fastic Plus has Fasting Buddies and weekly challenges. If accountability from others helps you stay consistent, Fastic is the better structural fit, even though its social layer is thinner than it sounds.
Step 5: Ask the 10-second question. What made you lose motivation with a health app before? Nothing kept my attention โก๏ธ Fastic. No one guided me through the hard parts โก๏ธ Simple.
Common Beginner Mistakes Both Apps Address โ
Mistake 1: Starting with a fasting window that is too long. Both apps guide beginners toward manageable starting windows during onboarding. Fastic's body status display makes a shorter fast feel like it accomplished something, which reduces the urge to jump to an unsustainable window in week one.
Mistake 2: Assuming fasting alone produces results without tracking food. A fasting timer measures when you ate, never what. Both apps ship food tracking for that reason. Fastic is more complete for calorie-focused users and gives it away free. Simple folds food quality into its Premium Success Score without asking you to count calories.
Mistake 3: Breaking the fast with a large, high-carbohydrate meal. Fastic's recipe library guides beginners toward balanced options for the first meal. Simple's Avo answers the same question on request, and Avo Vision will read a photo of what you are about to eat.
Mistake 4: Treating a missed fast day as a failure and quitting. Fastic's badge system is built to absorb a skipped day, according to the App Store reviewer quoted earlier; Fastic itself documents none of the mechanics. Simple's daily check-ins let you succeed on a given day regardless of whether you completed the full fasting window.
Mistake 5: Not adjusting the fasting window when life changes. Travel, social events and shift work create fasting conflicts. Fastic reviewers describe being able to choose which days they do not fast, though Fastic does not document how that interacts with streaks. Simple's coaching model works with imperfect adherence rather than requiring daily compliance.
Conclusion ๐ โ
For beginners in 2026, Fastic and Simple solve the same dropout problem through opposite mechanisms.
Fastic gives you the body status view, badge motivation, Fasting Buddies, a food and calorie tracker, two scanners and the Fasty chatbot, most of it on the free tier. If you are new to fasting and not yet ready to commit financially, Fastic is the lower-risk starting point.
Simple gives you Coach Avo, daily check-ins and streak tracking that build consistent behavior over weeks. Almost all of it is Premium, so Simple is the choice for someone who has already decided to pay for coaching.
Simple's Fortune #1 for 2026 reflects the strength of its coaching model. Fastic is absent from that list entirely, and its case rests on its store ratings instead: 246K App Store ratings at 4.8 out of 5.
Getting started matters more than picking the perfect app. Start with Fastic's free tier if you are not ready to pay. Start with Simple's Premium plan if coaching and habit structure matter more than knowing the price in advance. Either way, the habit you build in week one is worth more than the app you choose.
That exact feeling when you hit your fasting goal for the first time - both apps are designed to get you there
Frequently Asked Questions โ โ
Is Fastic or Simple better for complete beginners? โ
Fastic is generally better for beginners who want a meaningful free experience before paying, because its free feature block already carries the timer, Body Status, both scanners and the Fasty chatbot. Simple is better for beginners who want guided AI coaching from day one and are ready to pay for it, since the check-ins and streaks sit behind Premium. Fortune's 2026 round-up named Simple its best overall intermittent fasting app; Fastic does not appear on that list. Our own view, not Fortune's: Fastic is the stronger of the two on calorie tracking and community.
Does Fastic have an AI coach like Simple? โ
Fastic includes Fasty, an AI chatbot that both app stores list in Fastic's free feature block, which answers fasting and nutrition questions when you ask them. Simple's Avo AI is more proactive, running daily check-ins and streak tracking designed to build consistency over weeks, though Simple caps free users at two Avo replies a day. Avo is designed as a long-term habit coach; Fasty is designed as an on-demand reference tool.
Can beginners use both apps at the same time? โ
You can technically run both, but competing coaching signals and duplicate tracking create more friction than benefit. Pick one and stay with it for at least 30 days before evaluating. Most beginners who switch apps early do so before any habit has had time to form, which resets their progress more than the app choice itself.
Which app has a better refund policy? โ
Fastic's Feel Good Guarantee gives paid members a 14-day full refund with no usage conditions attached, though Fastic calls it a voluntary money-back guarantee rather than an entitlement. Simple offers a 30-day refund on website purchases and sends app store purchases to Apple and Google, with commitment subscriptions carrying a $29.99 fee for cancelling early. For first-time buyers, Fastic's flat guarantee has fewer moving parts.
How much does Fastic cost per year? โ
Fastic does not publish an annual price. Its US App Store listing showed ten concurrent Fastic Plus SKUs on 7 August 2026, from $12.99 to $79.99, and only two of them state a duration: $14.99 for one month and $27.99 for three months. Fastic's own description confirms 1-month, 3-month and 12-month terms exist without pricing the 12-month one. Simple publishes no prices at all and says the figure appears at checkout. Prices are standard US prices as of mid 2026 and change by region.
Does intermittent fasting actually work for beginners? โ
Yes, for most healthy adults. A 2022 narrative review in Nutrients drew on 66 articles published between 2010 and 2021 and reported that intermittent fasting regimens lead to a decrease in weight and have been linked to improvements in dyslipidemia and blood pressure, while noting that patient adherence remains a problem (Vasim et al., 2022). Both Fastic and Simple are built to attack that adherence problem, by different routes. Speak with your doctor before starting if you have existing health conditions, are pregnant, or take medications that require food timing.
