As a NutriScan nutritionist, I hear the same question from people starting intermittent fasting every week: Fastic or YAZIO? A 2023 clinical trial found that intermittent fasting paired with protein pacing produced greater weight loss, greater visceral fat loss, and a higher proportion of fat-free mass retained than calorie restriction alone, with both groups matched for energy intake (Arciero et al., 2023, PMC10107279). Both apps draw on this research, and they apply it in completely different ways.

Pick Fastic if: You want structured courses on fasting science and nutrition habits, gamified daily and weekly challenges, body stage tracking that shows what is happening inside your body, and a community accountability system to keep you consistent.
Pick YAZIO if: You want the cheaper of the two at every billing period, precise calorie and macro tracking alongside your fasting window, a large verified food database with AI photo scanning, and sync with a third-party fitness tracker.
What Each App Is Designed to Do
Fastic is a Berlin-built intermittent fasting app. Its core idea is that fasting needs a reason to continue, so it pairs the fasting timer with body stage education, habit courses, gamified rewards, and social accountability. The developer is Fastic GmbH, based in Berlin (Apple's listing still shows the legacy entity name HealthVida GmbH & Co. KG.). Fastic claims over 30 million downloads across both platforms (fastic.com), and carries 246,000+ App Store ratings at 4.8/5 and 421,000+ Google Play reviews at 4.4/5 (App Store, Google Play, both checked 2026-08-07). The download figure is Fastic's own cross-platform count, not an audited one; Google Play alone shows 10M+.
YAZIO began as a calorie tracker and grew into a combined calorie-and-fasting app. Its core idea is that you need accurate food data alongside your fasting schedule to get real results. Fortune named YAZIO the "Best Intermittent Fasting App with Calorie Tracking" in its best intermittent fasting apps guide, updated July 29, 2026 (Fortune). It holds 4.7/5 from 50K App Store ratings and 4.4/5 from 843K Google Play reviews (App Store, Google Play, both checked 2026-08-07). Apple now lists it as "AI Calorie Tracker by Yazio".
These two designs solve different problems. Fastic solves "I know I should fast but I keep giving up." YAZIO solves "I fast but I do not know if I am eating the right things during my eating window."
Starting your fasting journey - both apps help, but in very different ways
Fasting Plans: Protocol Variety and Depth

🧩 The meal scan trick (coming soon)
Only one of these two apps publishes its plan list, so start with what each vendor actually documents.
YAZIO names around 20 fasting plans, including 16:8, 12:12, 5:2 and 1:1 alternate-day fasting, plus manual custom windows you set yourself (YAZIO help centre, PRO features and fasting tracker). The same help article puts "all intermittent fasting plans" behind PRO, so the full library is a paid feature.
Fastic publishes no plan list at all. Its store listings describe intermittent fasting generically, so if a specific window matters to you, check it in the app before you pay.
A 2024 review in Foods looked at the common IF regimens and reached a more careful conclusion than most app marketing does: intermittent fasting has not yet shown a clearly superior profile to plain calorie restriction, and more convincing evidence is needed before it is treated as a gold standard (Brogi et al., 2024, PMC11241639). That is useful for choosing an app. If the protocol itself is not the deciding variable, the app that keeps you doing it matters more than the app with one extra window.
Where Fastic goes further is in two areas YAZIO does not have:
1. Protein Fasting mode. A protocol that combines a fasting window with high-protein meal guidance, high-protein recipes, and matching in-app courses. Fastic cites PMC10107279 directly on its Play listing: IF with protein pacing produced greater fat mass loss and a higher proportion of fat-free mass retained than calorie restriction alone. Of these two apps, Fastic is the only one shipping a protocol built around that finding.
2. Body Status tracking. During your fast, Fastic visualizes how your body is responding in real time, naming phases like fat burning and ketosis, in its own wording (Google Play).
YAZIO's fasting timer is accurate and clean. It records fasting start and end times, shows progress against your chosen window, and feeds eating window data into calorie tracking. Its Play description does include short guidance on ketosis, autophagy and energy use, so it is not silent on the biology, but there is no live phase visualizer and no protocol equivalent to Protein Fasting.
Winner for fasting plans: a tie. YAZIO documents more plans, Fastic ships the one protocol with a study behind it and the only real-time phase tracker. YAZIO's advantage is behind PRO; Fastic's Body Status is free.
Courses and Education: The Biggest Gap Between These Apps

👉 Courses, education, and gamification (current)
⏳ Calorie tracking and pricing breakdown
⏳ The meal scan trick (next)
This is where the two apps diverge most sharply, and it matters for long-term results.
Fastic Academy is the in-app course library included in Fastic Plus. Fastic calls it a "health knowledge hub" on the App Store and an "in-house academy" on Google Play, covering fasting, nutrition and healthy habits, with courses that pair to the Protein Fasting protocol (App Store, Google Play). Fastic publishes no course count or session length.
Alongside the Academy, Fastic Plus includes:
- Daily challenges - specific goal-oriented habits, framed by Fastic as habit-building
- Weekly challenges - multi-day engagement tasks to keep you coming back
- Fasting Buddies - connect with other users to share fasting progress and send encouragement
- Your daily plan - a day-by-day schedule tailored to your goals
YAZIO has no courses, no structured education programs, and no gamified challenge system. Its published PRO feature list runs to five headings and contains no course, academy, lesson or challenge (YAZIO help centre). Its learning comes from the nutritional data it displays after logging and from an external blog.
This gap matters for adherence, which is the weak link in the whole category. A 2022 review in Nutrients reports dropout of 38% in an alternate-day fasting arm against 29% for daily calorie restriction, and states plainly that patient adherence remains a problem across the trial literature (Vasim et al., 2022, PMC8839325). Roughly one in three people quit inside a study, where someone is checking on them. Apps that explain fasting at the moment you are tempted to break it have a plausible shot at that number; a countdown does not.
Winner for courses and education: Fastic - with no competition from YAZIO. The Academy is Fastic's most distinctive feature.
TIP
If you are new to intermittent fasting, the Academy is worth using in the first two weeks, before you hit your first difficult stretch at hour 14.
Calorie and Food Tracking: YAZIO's Core Strength
YAZIO is, at its foundation, a calorie tracker. Its food logging tools are more advanced than anything in Fastic's toolkit.
YAZIO food tracking, free and PRO:
- 4M+ food database, with verified entries YAZIO marks with a checkmark and locks against editing (Google Play, help centre)
- Barcode scanner, free, listed in the base calorie-counter block, not the PRO block
- AI photo food scanner, which launched free to everyone and has since moved behind PRO (YAZIO help centre)
- 3,000+ recipes with low-carb, vegetarian and vegan filters; full access is PRO
- PRO nutrient detail: fatty acids, fiber, sugar, salt, vitamins and minerals
- Custom meal plans by goal (weight loss, muscle gain, maintenance), PRO
- Activity sync with Fitbit, Garmin, Polar or Samsung Health (Android only), PRO; Apple Watch app; Health Connect on Android
- Ad-free in PRO. The free tier carries ads.
Fastic Plus calorie features:
- AI food scanner (Fastic Food Scanner) - instant calorie estimate from a photo
- Restaurant menu scanner - AI suggests dishes based on dietary preferences
- 4,500+ recipes sorted by dietary preference (low-carb, high-protein, vegan)
- Advanced food and menu scanner with more detailed nutritional breakdown
- Apple Health on iOS, Google Fit on Android. No direct Fitbit, Garmin, Polar or Samsung Health link.
Fastic has more recipes (4,500 vs 3,000). YAZIO's food database is far larger at 4M+ entries, and it is the only one of the two that breaks a meal down to vitamins and minerals, though that detail is PRO-gated.
Fortune's guide named YAZIO the best intermittent fasting app for people who want the timer and accurate calorie tracking in one product (Fortune).
Winner for food tracking: YAZIO - much larger database, third-party wearable sync, and micronutrient detail Fastic does not offer at any tier.
Pricing Breakdown for 2026 💰
This is where the comparison becomes most concrete. Prices are standard US prices as of mid 2026 and change by region.
Fastic Plus Pricing
| Plan | Price | Monthly Cost | Savings vs Monthly |
|---|---|---|---|
| 1 Month | $12.99 - $14.99 | $12.99 - $14.99 | - |
| 3 Months | $27.99 - $29.99 | ~$9.33 - $10.00 | ~28% |
| 12 Months | $79.99 | $6.67 | ~49% |
All three rows are live in-app purchases on the US App Store listing as of 2026-08-07. The 49% annual saving is measured against the $12.99 monthly SKU; against the $14.99 one it is 55%.
Fastic runs promotional pricing rather than one list price. The same App Store listing shows ten Fastic Plus SKUs at the same time, including discounted tiers at $19.99, $29.99 and $39.99 with no duration attached, so the price you are offered depends on your region and which onboarding flow you were shown. Apple does not label those durations, so there is no way to state a Fastic annual promo floor honestly.
YAZIO PRO Pricing
| Plan | Price | Monthly Cost | Savings vs Monthly |
|---|---|---|---|
| 1 Month | $11.90 | $11.90 | - |
| 3 Months | $23.99 | $7.99 | ~33% |
| 6 Months | $34.99 | $5.83 | ~51% |
| 12 Months (list) | $47.90 | $3.99 | ~66% |
| 12 Months (promo SKU) | $23.90 | $1.99 | ~83% |
Both 12-month SKUs are live at once on the US App Store listing, so $23.90 is not a past cycle you missed. YAZIO also runs a 40% student discount through Student Beans, which prices the annual plan at $28.75 and is limited to new users without a current PRO membership (Student Beans).
Figure 1: At every published billing period, YAZIO's list price is lower than Fastic's
At list pricing, YAZIO PRO ($47.90/yr) costs $32/yr less than Fastic Plus ($79.99/yr). Against YAZIO's live $23.90 SKU the gap is $56/yr. Over three years that is $96 to $168.
Winner for pricing: YAZIO - lower list price at every billing period, a student discount, and a 6-month plan Fastic does not offer.

✨ The meal scan step that fixes the blind spot both apps share (about to reveal)
Both apps offer free versions with no time limits. What you get for free differs considerably.
Fastic Free
- Fasting timer (Fastic does not publish which windows are free, so check in-app)
- Body Status tracker - shows current fasting phase in real time
- Food and calorie tracker
- AI food scanner (Fastic Food Scanner) for meal photo analysis
- Restaurant menu scanner with AI dish suggestions
- Fastic Score tracking nutrition, hydration, sleep, and activity
- AI chat (Fasty) for instant fasting and nutrition guidance
- Step counter, water tracker with reminders
- Apple Health on iOS, Google Fit on Android
Every item above sits in the base feature block of Fastic's own store listings, before the Fastic Plus section starts. You can fast, scan meals, get AI coaching and watch your body status phases without paying.
YAZIO Free
- Calorie diary against the full 4M+ food database
- Barcode scanner, which is in the base feature block, not the PRO one
- Food ratings, step tracking and water tracking
- Recipe browsing, with full access reserved for PRO
- Fasting tracker with the basic plans. PRO adds "all intermittent fasting plans"
- Ads. YAZIO's Play listing is marked "Contains ads"
Two things commonly written about YAZIO's free tier are wrong. The barcode scanner is free, listed in the base calorie-counter block and absent from the PRO feature list (Google Play, PRO features). And recipes are browsable free; PRO buys full access, not first access. What PRO genuinely gates is the AI photo scanner, the full fasting plan library, detailed macro and micronutrient breakdowns, wearable sync, meal plans and the ad-free app.
Winner for free tier: a tie. Fastic gives away AI photo scanning, the menu scanner and the body status tracker. YAZIO gives away a 4M-entry database with a barcode scanner, which is what you reach for on packaged food. Neither free tier is a stub.
Trial and Refund Policies
Fastic: 14-Day Feel Good Guarantee
Fastic charges you upfront for your chosen plan. Within the first 14 days, if Fastic is not right for you, you receive a full refund with no conditions, no usage requirements, and no deductions. Fastic's own policy page says it "consciously waives" the digital product exclusions that would normally let it keep the payment, and spells out that you do not have to follow a plan, use the timer regularly, update your weight or hit any result (Feel Good Guarantee). Claim it at [email protected] or through the help centre.
YAZIO: 7-Day Trial, With a Catch
YAZIO's 7-day PRO trial gives full access with no limits, and cancelling inside the seven days costs you nothing. The catch is availability. YAZIO's help centre states the trial "is offered occasionally and is available only on our website", and that you cannot subscribe to it from inside the app (YAZIO help centre).
The practical difference: Fastic's 14 days of full paid access is always there and needs a refund request. YAZIO's 7 days needs no refund request but may not be on offer when you look, and you have to start it on yazio.com rather than in the app.
TIP
Use Fastic's 14-day guarantee strategically. Pay for a full subscription, test every Plus feature in the first two weeks, and request a refund if the courses and challenges do not add enough value. The risk is zero.

Final score: Fastic wins 6 categories, YAZIO wins 5, with 3 ties. That is close enough that the tally decides nothing. Read the rows, not the total.
How to Choose: 3 Steps
Choosing between these two apps takes three honest questions.
Step 1: Do you want structured education or just the tools?
If you are new to intermittent fasting, struggle to stay consistent past week two, or want to understand the science behind what you are doing - Fastic's Academy is the better fit. If you already understand IF and just need a timer and tracker, YAZIO gives you better tools for less money.
Step 2: How precisely do you need to track what you eat?
If you log every meal and want accurate macros from a large database with wearable sync to your fitness tracker, YAZIO is the more precise instrument. If you fast primarily and track food loosely, Fastic's basic tracker handles the job.
Step 3: What is your annual budget?
At list pricing, YAZIO saves $32/yr. Against its live $23.90 SKU, $56/yr. Over three years, $96 to $168. If the Academy courses and gamification are not features you will use, the price difference alone makes YAZIO the practical choice.
Tips for Getting the Most from Either App 💡
These habits make the first four weeks more successful regardless of which app you choose:
- Start with a realistic fasting window, not the most ambitious one. Most beginners do well with 12:12 or 14:10 for the first two weeks before moving to 16:8.
- Set your eating window at the same time every day. Fasting at inconsistent hours makes hunger harder to manage and breaks the habit loop.
- Use Fastic's body stage tracker as your anchor during hard fasting hours. Seeing that you are in the fat-burning phase at hour 14 is more useful than fighting hunger with willpower alone.
- In YAZIO, connect your tracker on day one. Activity sync with Fitbit, Garmin, Polar or Samsung Health is a PRO feature, so if you are paying, turn it on immediately. Real burn data changes how the app reads your eating window.
- Try the Fastic Academy in the first week if you choose Fastic. Courses cover fasting, nutrition and habits, and they are most useful before you hit your first difficult stretch.
- Check both YAZIO 12-month SKUs before you buy. $23.90 and $47.90 are both live on the App Store, so the price you are shown at signup is not necessarily the cheapest one on offer.
- Use the 14-day guarantee if you choose Fastic. Pay for a full subscription, test every Plus feature in the first two weeks, and request a refund if the courses and challenges do not add enough value.
The One Thing Neither App Tells You About Fasting Results ✨
IMPORTANT
Recap: everything you completed this round.
You finished the run - save this for next time.
⏱️ Progress 4/4 - ~4 minutes in - Nicely done
✅ Fasting plans and protocol variety
✅ Courses, education, and gamification
✅ Calorie tracking and pricing breakdown
✅ The meal scan trick (revealed)
Here is what the comparison above does not cover - and it is the variable that decides results more than which app you pick.
Both Fastic and YAZIO assume you can accurately log what you eat in your eating window. For most people, that assumption is wrong.
The most common failure in intermittent fasting is not breaking the fast. It is unknowingly overeating in the eating window and wiping out the calorie deficit that IF creates. In a 2019 Cell Metabolism trial, four weeks of strict alternate-day fasting cut average calorie intake by 37% in healthy, non-obese adults, without anyone counting a calorie (Stekovic et al., 2019, PMID 31471173). That deficit only shows up if you do not compensate on eating days, and most people cannot tell whether they have.
Where both apps struggle: neither gives you accurate meal data from a single photo without manual correction. YAZIO says so itself. Its help centre states the AI recognition "only provides a rough estimate and cannot guarantee 100% accurate results" and asks you to review and edit your entries (YAZIO help centre).
The fix is meal photo scanning with AI portion correction.
When you scan a plate of food with NutriScan, the app identifies the meal, estimates macros, and then asks you to confirm cooking method and portion size before the meal is logged. Same question YAZIO tells you to ask yourself, asked up front instead of left to you.

The combination that works: use Fastic's 16:8 timer and Academy courses for habit building ➡️ use NutriScan's photo scan at each meal in your eating window ➡️ get calorie accuracy that neither app achieves alone.

Research Behind Intermittent Fasting Apps
Intermittent fasting has a real research base, and it is less settled than app marketing suggests.
A 2024 review in Foods examined the common IF regimens, including time-restricted eating, 5:2 and alternate-day fasting, and concluded that IF has not yet demonstrated a clearly superior profile compared with a well-established calorie-restriction intervention, and that more convincing evidence is needed before IF is sponsored as a gold standard for weight management (Brogi et al., 2024, PMC11241639).
The Protein Fasting protocol featured in Fastic is grounded in a 2023 clinical trial. Intermittent fasting with protein pacing produced greater reductions in weight (9% vs 5%), total fat (16% vs 9%) and visceral fat (33% vs 14%) than calorie restriction, with both groups matched for energy intake and activity. Absolute fat-free mass fell in both groups by about 1.5 kg; what improved was the proportion of fat-free mass retained (Arciero et al., 2023, PMC10107279).
Adherence is the variable that decides outcomes. A 2022 review in Nutrients reports 38% dropout in an alternate-day fasting arm against 29% for daily calorie restriction, and notes that patient adherence remains a problem across the trial literature (Vasim et al., 2022, PMC8839325). That is the case for Fastic's Academy and challenge system. They attack the quit rate with education and motivation rather than a better timer.
INFO
Want to check your macro targets for intermittent fasting? Use NutriScan's macro calculator to find your protein, carb, and fat targets before you start your eating window.
Conclusion
Fastic and YAZIO solve different problems for fasting users in 2026.
Fastic is the better app if you want a structured fasting education program with courses, gamified challenges, real-time body status, and a peer accountability system. At $79.99/yr list it costs more than YAZIO, and it gives you a habit-building platform alongside the timer.
YAZIO is the better app if you need accurate calorie and macro tracking alongside your fasting window. Fortune named it the best intermittent fasting app with calorie tracking, and its 12-month plan runs $47.90 list with a $23.90 SKU live at the same time. Its food database, third-party wearable sync, and micronutrient detail are stronger tools for precision-focused trackers.
Neither app alone solves the eating window accuracy problem. If you pair either with NutriScan, you get AI-powered meal photo analysis alongside your fasting window - showing exact macros and portion data from a single food photo, so your eating window logging is as accurate as your fasting window tracking.
Frequently Asked Questions ❓
Q: Is Fastic better than YAZIO for intermittent fasting in 2026?
A: Fastic is better for structured habit-building. It has the Academy courses, real-time body status, gamified challenges, and Fasting Buddies that YAZIO does not offer. YAZIO is better for users who prioritize precise calorie and macro tracking alongside their fasting window, with a 4M+ food database, third-party wearable sync, and a lower list price. On a category tally the two finish 6 to 5 with 3 ties, so the honest answer is that it depends on which problem you need solved: motivation and education (Fastic) or nutritional accuracy (YAZIO).
Q: Does YAZIO have an academy or courses like Fastic?
A: No. YAZIO's published PRO feature list runs to five headings and contains no course, academy, lesson or challenge (YAZIO help centre). Its learning comes from the nutritional data displayed after logging and from a separate external blog, though its Play description does include short guidance on ketosis, autophagy and energy use. For guided education across fasting biology and habit formation, Fastic's Academy is the only option between the two.
Q: Which app is cheaper - Fastic or YAZIO in 2026?
A: YAZIO. The list annual price is $47.90/yr for YAZIO PRO against $79.99/yr for Fastic Plus, a $32/yr difference. YAZIO also runs a $23.90 12-month SKU live on the App Store at the same time, widening the gap to $56/yr. YAZIO adds a 40% student discount through Student Beans ($28.75/yr, new users only) and a 6-month plan ($34.99) that Fastic does not have. Prices are standard US prices as of mid 2026 and change by region.
Q: Does Fastic offer a free trial in 2026?
A: Fastic does not offer a traditional free trial. It offers the "Feel Good Guarantee": you pay upfront, and if you decide within 14 days that Fastic is not right for you, you get a full refund with no usage conditions (Feel Good Guarantee). YAZIO has a 7-day PRO trial with no upfront charge, but its help centre says the trial is offered occasionally and only through yazio.com, not inside the app.
Q: What fasting protocols does each app support?
A: YAZIO documents around 20 fasting plans, including 16:8, 12:12, 5:2 and 1:1 alternate-day, plus manual custom windows, all behind PRO. Fastic does not publish its plan list, so check the windows you want before paying. What Fastic adds is Protein Fasting, a protocol pairing a fasting window with high-protein meals and recipes and backed by PMC10107279, and a Body Status tracker showing your fasting phase in real time.
Q: Can I use both Fastic or YAZIO alongside NutriScan?
A: Yes. Many users run Fastic or YAZIO for the fasting timer and community features, then use NutriScan to scan meals during their eating window for macro and calorie data. NutriScan asks you to confirm cooking method and portion before a meal is logged, which is the step both apps leave to you.
