TL;DR - Simple Premium 2026 Verdict

  • Price: $29.99/month (Premium) or $14.99/month (Pro). Annual plan drops Premium to roughly $5/month - about 70% cheaper than monthly.
  • Free plan is thin: basic timer, capped Coach Avo, no photo or voice logging, limited content.
  • Premium upgrades worth paying for: unlimited Coach Avo, photo + voice meal logging, full nutrition scores, habit-building workbooks, full content and recipe library, customizable fasting schedules.
  • Pay if you are new to fasting, want behavior-change workbooks, prefer scores over calorie counts, or use Avo daily as an accountability partner.
  • Skip if you only want a fasting timer, you already prefer calorie/macro tracking, or you need human coaching over AI.
  • Sneak preview: the one Premium feature most users sleep on in week one is buried halfway through this post 👀

🔍 The one Premium feature most users miss in week one (revealed near the end)

As a NutriScan nutritionist, I test intermittent fasting apps every few months to see what has actually improved and what is still marketing fluff. Simple holds a 4-star rating on Trustpilot from over 7,000 reviews (Trustpilot, 2026) and Fortune named it the "Best Intermittent Fasting App Overall" for 2026 (Fortune, 2026). Those numbers sound great. But a high overall rating does not tell you whether the paid version is worth your money.

I spent three weeks switching between the free and Premium tiers of Simple to find exactly where the upgrade pays off and where it does not. This review walks through every Premium feature, the new pricing, how Coach Avo actually performs, and gives you a clean pay-or-skip verdict.

What You Already Get for Free 🆓

Before we talk about what Premium adds, here is the floor. The free plan covers the bare basics:

  • Basic fasting timer with default schedules (12:12, 14:10, 16:8)
  • Limited daily messages with Coach Avo (the AI assistant)
  • A small slice of the educational content library
  • Apple Health and Google Fit sync
  • Manual weight tracking

You do not get photo logging, voice logging, full nutrition scoring, the workbooks, or the full content and recipe library. The free tier is essentially a try-before-you-buy timer, not a full app.

Person checking a fasting timer app on their phoneMost people start at the free tier - the timer is genuinely fine for that.

What Simple Premium Adds 💎

Premium unlocks the features that make Simple feel like a coach, not just a timer.

Coach Avo: Unlimited AI Coaching 🤖

Coach Avo is the feature that sets Simple apart from every other fasting app. It is an AI chatbot trained by health experts that can answer nutrition questions, suggest meal improvements and give personalized feedback on logged meals.

When I tested it, Avo was consistently helpful for quick questions. I logged a chicken salad for lunch and Avo suggested adding a handful of nuts or seeds to lift fiber and healthy fats. I asked about the best foods to break a 16-hour fast and it recommended starting with something easy to digest like eggs or yogurt with fruit.

Avo is honest about its limits. The bot states it is "trained by health experts but can't replace medical guidance" (Everyday Health, 2025). Some competitor apps present their AI features as if they were human dietitians. Simple does not.

The free version gives you a handful of Avo interactions per day. Pro extends that significantly. Premium removes the limit entirely. For someone who logs three meals and asks a few questions, Pro is enough. If you use Avo as a daily accountability partner with detailed feedback on every meal plus snack ideas, Premium is the right tier.

Photo and Voice Meal Logging 📸

Photo logging is Premium-only. You photograph your plate, the app identifies the foods and assigns a nutrition score. During my testing it worked well about 80% of the time - it correctly identified a bowl of oatmeal with berries, a grilled salmon plate and a simple pasta dish. It struggled with mixed dishes like stir-fries and soups, often asking me to confirm or correct the ingredients.

Voice logging works the same way - say "two scrambled eggs with toast and avocado" and the app logs it. For people who hate manual entry, this single feature can be the reason to upgrade.

Nutrition Scoring (1-4) Across Every Meal

Every meal you log receives a score from 1 (low quality) to 4 (optimal) based on protein, fiber, saturated fat, sodium and calcium (Everyday Health, 2025). The criteria are simpler than full macro tracking but enough to nudge real choices.

In practice the system works well for main meals. A grilled chicken breast with vegetables and brown rice scored a 4. A fast-food burger with fries scored a 2. The feedback was clear and actionable.

Where it falls short: snacks. A small handful of almonds scored lower than expected because the system seemed to weight fat content heavily without distinguishing between unsaturated and saturated. A banana scored differently depending on whether it was logged alone or as part of a meal. Past nutrition scores can also disappear from the app, which is frustrating for anyone trying to spot weekly patterns.

Habit-Building Workbooks (Premium-Only) 📒

This is where the Premium tier separates from Pro. The workbooks are structured programs covering emotional eating, mindful eating, stress management and exercise habits. Each workbook includes daily exercises, reflections and small challenges.

A 2021 study in the International Journal of Clinical and Health Psychology found that psychological well-being plays a significant role in weight-loss outcomes - participants who addressed psychological factors lost more weight than those focused on diet alone (Zhu et al., 2021). Simple's workbooks target this psychological layer directly. None of this content is available in free or Pro.

Pro tip

If you have tried fasting before and "fall off" after 2-3 weeks, the workbooks are likely the feature that justifies Premium for you. The fasting timer is not your problem - the eating-around-the-fast is.

Customizable Fasting Schedules

Premium lets you adjust your schedule daily, run guided fasting programs and pick non-default windows. The app caps fasting at 24 hours and most plans default to 12:12, 14:10 or 16:8 - consistent with the research. A 2022 meta-analysis of randomized controlled trials found 16:8 time-restricted eating effective for reducing body weight and BMI in overweight and obese adults (Huang et al., 2022).

Shannan Bergtholdt, RD, called this flexibility a key strength: "Simple offers users the flexibility to change their fasting windows during the week to correlate with the natural fluctuations in their schedules and lives" (Everyday Health, 2025).

Full Content Library and Recipe Hub

Premium opens the full Explore tab - educational content, exclusive courses, workout plans and a complete recipe library organized by goal. Free users see a small slice; Premium users get everything.

Pricing: Free vs Pro vs Premium 💰

Simple offers two paid tiers through the App Store: Pro at $14.99/month and Premium at $29.99/month (Apple App Store, 2026). Longer plans bring the price down. A three-month plan runs about $9.99/month and an annual plan drops to roughly $5/month (Everyday Health, 2025).

The most important difference between Pro and Premium is the depth of Coach Avo access plus the workbooks and habit tools. If you do not care about the workbooks, Pro is a much better deal.

Real-World Examples: Who Benefits Most 👤

Maya, 31 - New to Intermittent Fasting

Maya has tried 16:8 twice and quit after 10 days both times. Her problem is not the timer; it is what she eats during the eating window. Premium pays off here - the workbooks address emotional eating and stress, Coach Avo nudges meal choices, and the nutrition scores teach her what "good" looks like without macro spreadsheets.

Jordan, 38 - Experienced Faster, Just Needs a Timer

Jordan has been doing 18:6 for three years. He logs his eating window mentally and tracks calories in MyFitnessPal. Skip Premium. Zero free or Simple free is enough - the timer alone covers his needs.

Priya, 27 - Wants Photo Logging and Daily Coaching

Priya wants the camera-based logging and an AI to ask quick questions. She does not need the workbook content yet. Pro is the right pick - $15/month gets her photo logging and extended Avo without the Premium bump.

Quick self-check: which one are you?

Mostly Maya ➡️ Premium pays for itself.
Mostly Jordan ➡️ stay free, or use Zero free.
Mostly Priya ➡️ start with Pro, upgrade to Premium only if you crave the workbooks.

Tips for Getting the Most Out of Premium 💡

  1. Start with the free version for one week. Log meals, try the timer, talk to Avo within free limits. Confirm scores-over-calories matches your style before paying.
  2. Pick the annual plan to save ~70%. Monthly is the most expensive option. Annual runs about $60/year vs $360/year monthly.
  3. Run one workbook end-to-end before starting another. The temptation is to skim three. The single biggest predictor of behavior change is finishing one.
  4. Use Avo as a meal-improvement coach, not a nutrition encyclopedia. Ask "how do I improve this meal" with a photo, not "what is the best diet for me."
  5. Schedule a 30-day check-in. Open Progress on day 30. If your scores have not improved and you have not fasted consistently, cancel.
  6. Cancel through your phone's subscription manager. Some users have reported the in-app cancel button is hard to find (Reddit, 2024). Apple App Store and Google Play settings handle it cleanly.

Step-by-Step: How to Decide if Simple Premium Is Worth It 🧭

Step 1: Use Simple Free for One Full Week

Download Simple, run a 14:10 or 16:8 schedule, log meals manually, and chat with Avo within the free limits. Pay attention to where the free tier feels short.

Step 2: Identify the Gaps

Did you hit the Avo message limit by day three? Did you wish you could photo-log instead of typing? Did you want guidance on emotional eating, not just a timer? Write the gaps down.

Step 3: Match Gaps to Tier

  • Mainly Avo + photo logging gaps ➡️ Pro at $14.99/month
  • Workbooks, habit tools and full content library matter ➡️ Premium at $29.99/month
  • Just want a timer ➡️ stay on free or move to Zero free

Step 4: Pick Annual If You Plan to Stay 3+ Months

The annual plan is roughly $60/year vs $360/year monthly. Break-even is about three months. If you have failed at fasting twice before, that is already your timeline.

Step 5: Set a 30-Day Review

On day 30, open Progress. Have your nutrition scores improved? Are you fasting consistently? If yes, continue. If not, cancel before renewal.

How Simple Compares to Other Fasting Apps 📊

AppMonthly PriceCalorie CountingAI CoachFasting FocusBest For
Simple Premium$29.99No (scores)Coach AvoPrimaryHabit building without counting
Zero Plus~$5.83/mo annualNoNoPrimaryFree-tier fasting timer users
DoFasting$11-20YesNoPrimaryFasting + meal plans + workouts
YAZIO PRO~$4/mo annualYesLimitedSecondaryDetailed calorie + macro tracking
Noom$42-59YesYesNoPsychology-based weight loss

Simple's biggest competitor for the "no calorie counting" approach is Zero, which offers a strong free tier with timers, journals and community challenges. Zero Plus is about $70/year, much cheaper than Simple Premium annual. But Zero does not include AI coaching, nutrition scoring or structured habit tools.

For users who want fasting plus detailed calorie tracking, YAZIO PRO or DoFasting offer more value per dollar. Simple's edge is its simplicity and behavior-change focus.

Watch out

A 2024 Nutrients review on AI photo analysis showed photo-based estimation still has a roughly 26.9% mean absolute error on complex meals (Fang et al., 2024, Nutrients). Use Simple's photo logging as a starting point, then nudge portions for foods with hidden oils, sauces or mixed ingredients.

NutriScan Side-by-Side: When We're a Better Pick 🔄

NutriScan is built for people who want AI photo scanning + a personalized diet plan + behavior science in one app, not a fasting-first experience. Where Simple wins on fasting workflow, nutrition scoring and habit workbooks, NutriScan wins on:

  • Photo-first logging with AI-estimated portions and a re-scan flow if you don't like the count
  • Personalized diet plan built from your goal (Weight Loss, Muscle Gain, Diabetes, Pregnancy, PCOS) and your food preference (Vegan, Vegetarian, Eggitarian, Non-Veg)
  • NutriBites daily questions that nudge habit change instead of pure data entry
  • Insights widgets like the Calendar and City Map that surface streaks and patterns visually
  • Voice logging through Monika, our AI assistant, for hands-free meal entry

If you're stuck between the two

Pick Simple Premium if your priority is fasting structure + habit workbooks. Pick NutriScan if your priority is photo-first logging, a built-in diet plan, and lightweight habit nudges without a fasting-first interface. Set your macros first with our free macro calculator before testing either.

Research on Fasting Apps and Behavior Change 🔬

The big question is whether app-guided fasting actually works. The research is encouraging but comes with caveats.

A 2024 umbrella review in PMC analyzed multiple systematic reviews and meta-analyses of intermittent fasting. The findings showed IF was consistently effective for weight loss and metabolic markers including cholesterol and blood sugar (PMC, 2024). A 2025 BMJ review confirmed intermittent fasting strategies produced weight-loss results similar to continuous calorie restriction (BMJ, 2025).

A 2023 randomized controlled trial in Annals of Internal Medicine found that time-restricted eating without calorie counting produced meaningful weight loss in a racially diverse population of 90 adults over 12 months (Lin et al., 2023). Simple's score-not-count approach aligns with this finding directly.

These studies tested the fasting protocol, not specific apps. What we know is that self-monitoring tools improve adherence to health behaviors. Translation for the Premium question: if Simple helps you fast more consistently and pick better meals, the subscription pays for itself. If you already fast consistently without an app, Premium improves the experience but may not change outcomes.

The One Premium Feature Most People Miss in Week One 🕵️

I told you up top there is a feature most users sleep on. Here it is: the workbooks, used as a 4-week sequence, not a buffet.

On their own, "habit workbooks" sounds like content most people skim. Used as a 4-week sequence with one workbook per week, it becomes the single most useful behavior-change loop in the app:

  1. Week 1: Mindful Eating workbook. One small daily exercise, no fasting changes.
  2. Week 2: Emotional Eating workbook. Identify two trigger moments per day, no diet changes.
  3. Week 3: Stress and Sleep workbook. Add a 10-minute wind-down, keep your existing fasting window.
  4. Week 4: Exercise Habit workbook. Pick one movement target per day - walk, stretch, lift.

Most users open the workbooks once, read the first page of two of them, then ignore the tab. Used as a sequence with one workbook a week, the compounding is real and lines up with the 2021 International Journal of Clinical and Health Psychology finding on psychological factors and weight-loss outcomes (Zhu et al., 2021).

That single use pattern is what separates the $5/month annualized Premium experience from a glorified fasting timer. If you will not run a workbook end-to-end, you do not need Premium - get Pro.

Who Should Pay for Simple Premium ✅

Pay for Premium if you:

  • Are new to intermittent fasting and want structured guidance beyond a timer
  • Prefer nutrition scores over calorie counting and want feedback on every meal
  • Will actually run the habit workbooks for at least 4 weeks
  • Use Coach Avo daily as an accountability partner and hit the free limit fast
  • Want an all-in-one app for fasting, meal feedback, workouts and education

Skip Premium if you:

  • Already know your fasting schedule and just need a timer (use Zero free)
  • Want detailed calorie + macro tracking (use YAZIO, MyFitnessPal or NutriScan)
  • Are on a tight budget and cannot justify $29.99/month
  • Prefer human coaching over AI (consider Noom or a registered dietitian)
  • Mainly want recipes and meal plans (DoFasting offers more for less)

Consider Pro instead of Premium if you:

  • Want photo logging and extended Coach Avo access but won't open the workbooks
  • Are comfortable building habits without structured programs
  • Want to save $15/month while keeping the core paid features

Conclusion 📝

Simple Premium is a solid pick for a specific user: someone who is new to fasting, prefers scores over calories, and will actually use the habit-building workbooks. At $29.99/month monthly billing it is one of the more expensive fasting apps on the market - but the annual plan brings it down to about $5/month, competitive with YAZIO PRO and DoFasting.

The strongest arguments for Premium are unlimited Coach Avo and the workbooks. If those tools help you stay consistent and make better food choices, the subscription pays for itself in outcomes. If you only need a fasting timer, free alternatives do the job for free.

My recommendation: start with the free version for one week, upgrade to Pro if Avo and photo logging are the only gaps, upgrade to Premium annual only if you will run a full workbook sequence. For broader nutrition tracking with photo-first logging and a built-in diet plan, try NutriScan alongside Simple, or compare options in our Cal AI Premium 2026 review and MyNetDiary Premium 2026 review. Plan macros first with our online macro calculator or our PCOS macro calculator if you have insulin-related concerns, and read our meal scan guide for tips on photo-based logging.

Frequently Asked Questions ❓

Q: Is the Simple app free or paid?

A: Simple offers a free version with a basic fasting timer and limited Coach Avo access. The paid app comes in two tiers - Pro at $14.99/month and Premium at $29.99/month. Annual plans drop the price to roughly $5/month, around 70% cheaper than monthly billing.

Q: Does the Simple app have a free trial?

A: Simple does not offer a traditional free trial of its paid plans (Fortune, 2026). The free version stays available indefinitely so you can test basic features before deciding to upgrade. Some users report seeing in-app trial offers, but they are not guaranteed.

Q: What is Coach Avo in the Simple app?

A: Coach Avo is an AI chatbot trained by health experts. It answers nutrition questions, suggests meal improvements, gives feedback on logged meals and sends daily tips. Avo is transparent that it cannot replace medical guidance. Free limits daily messages, Pro extends them and Premium removes the limit entirely.

Q: Can I cancel Simple Premium and get a refund?

A: You can cancel at any time through Apple App Store or Google Play subscription settings. Simple states cancellation is allowed within 30 days of signing up or before automatic renewal. Some users have reported the in-app cancel button is hard to find, so using your phone's subscription manager directly is recommended.

Q: How does Simple compare to Zero for intermittent fasting?

A: Simple focuses on AI coaching, nutrition scoring and habit-building workbooks without calorie counting. Zero focuses on a strong free fasting timer and community challenges. Zero Plus is about $70/year, much less than Simple Premium annual. If you mainly need a fasting timer, Zero is the better value. For AI coaching and behavior-change tools, Simple offers more features.

Q: Is the Premium tier worth $30/month?

A: Monthly billing is rarely the right pick. The annual plan at ~$5/month is the value answer for users who will actually use the workbooks and unlimited Coach Avo. If you want photo logging and extended Avo only, Pro at $14.99/month is the smarter spend.

Q: Will Simple actually help me lose weight?

A: Indirectly. The 2024 PMC umbrella review found intermittent fasting consistently produces weight loss when followed consistently (PMC, 2024). The app helps you fast more consistently and pick better meals - which translates to results. If you already fast consistently without an app, Premium improves the experience but may not change outcomes much.

Q: Does Simple work without calorie counting?

A: Yes - that is its core design. Simple replaces calorie counts with a 1-4 nutrition score based on protein, fiber, saturated fat, sodium and calcium. The 2023 Annals of Internal Medicine RCT supports this approach: time-restricted eating without calorie counting produced meaningful weight loss over 12 months (Lin et al., 2023).
