Aumaï vs Simple: Fasting Coach or AI Coach?

Simple's App Store page shows 407,000 ratings at 4.7 stars, and in 2026 Fortune named it the best intermittent fasting app overall. If you have looked for a weight-loss app this year, you have probably met Avo, its AI coach, or Blinky, the cartoon mascot that cheers when you log a salad and sulks when you skip. Both Simple and Aumaï put an AI coach at the center. They bet on very different versions of what that coach should do.

This is a fair look at where each one shines, so you can pick the tool that matches how you actually want to eat.

Key Takeaway: Simple coaches behavior change around intermittent fasting and deliberately skips calorie counting. Aumaï gives you the exact numbers plus a coach that remembers you, across WhatsApp, web, and app.

What Simple does well

Simple is a weight-loss app built around intermittent fasting and gentle habit change. Its method avoids calorie counting, cutting food groups, and weighing every bite. Instead it nudges you toward a fasting window, more water, more movement, and small daily actions scored by a real-time Success Score.

The coaching is genuinely likeable. Avo is a 24/7 in-app assistant that gives feedback on meals, suggests a fasting schedule, and sets a short daily plan after a quick check-in. Premium adds Avo Vision, which scans a meal, a menu, or your groceries and returns an estimate and recipe ideas. The mascot, Blinky, turns consistency into a game, which is part of why Simple pitches itself as the Duolingo of health.

The credibility is real too. Simple holds a 4-star Trustpilot rating across more than 7,000 reviews, carries a 4.7 average on the App Store, and won several industry awards in 2025 and 2026. For someone new to fasting who wants encouragement over spreadsheets, that is a strong package.

Stat: Simple's free plan never expires, but photo logging, voice logging, full nutrition scoring, and unlimited Avo messages sit behind Premium.

Where Aumaï wins

You get the numbers, not just a score. Simple is open about skipping calorie counting. That suits some people and frustrates others. Aumaï tracks calories and 6 macronutrients including fiber, which many apps leave out. If you want to know a meal was 610 kcal with 35 g of protein, Aumaï tells you, then explains what to do with that.

The coach actually remembers you. Aumaï keeps your goals, habits, and allergies in context from one conversation to the next. Avo personalizes your daily plan, but Aumaï's persistent memory means advice on a Tuesday builds on what you ate last week, not just today's check-in.

It lives in WhatsApp. There is nothing to install and nothing new to learn. You send a photo, a message, or a voice note, and it is logged in seconds. Simple is a mobile app you open; Aumaï meets you in a chat you already use all day, and the same memory follows you to web and app.

One flat price. Aumaï is EUR 4.99 a month with everything included. Simple's annual plan lands near USD 5 a month, but the month-to-month price is USD 29.99, and the features that make it feel like a coach are Premium-only.

It explains the why. When you log a quiche, Aumaï tells you it is high in saturated fat and suggests a swap. That education-first habit is closer to how a good human coach talks.

Where Simple may suit you better

Simple is a better fit if intermittent fasting is your main strategy and you want a dedicated timer with schedules built in. Its fasting features are more developed than Aumaï's, which treats fasting as one tool rather than the centerpiece.

It also wins on playful motivation. If a cartoon character reacting to your choices is what keeps you logging, Blinky is good at that job. And if numbers stress you out, Simple's no-calorie-counting method may feel lighter than an app that shows you macros every day. The science on meal timing is still evolving, as our piece on time-restricted eating and the brain explores, so a fasting-first app makes sense for some goals.

The verdict

Pick Simple if you want a fasting-first app with cheerful, gamified coaching and you would rather avoid calorie math. Pick Aumaï if you want the exact numbers, a coach that remembers your history, fiber tracking that most apps skip, and the convenience of logging straight from WhatsApp for EUR 4.99 a month. Simple makes healthy habits feel fun. Aumaï makes them clear, then helps you change the next meal. If you care about understanding what you eat and not just checking a box, Aumaï is the stronger daily tool. Getting enough fiber is one example of something Aumaï surfaces that a score-based app can hide.
