Recipes, activity and intermittent fasting

Slim AI gives you more than calorie counting. Track your workouts, run intermittent fasting and get meal recipes made for you.

Meals made for you

Take a photo of your fridge, add what is in the cupboard, set how hungry you are and get meal ideas with full step by step instructions.

Time left in your eating window:

04:41:32

Start: Today 10:00

End: Today 18:00

@guzins.ha
I used to use fitatu, but since I started counting calories in Slim AI I no longer spend hours looking for products, thanks to the AI feature that makes everything easy and simple even for my parents.
@igi.di
bulking with this app is pure pleasure, I got hooked on it😍
@m_popardowski
I absolutely love this app, counting calories is super simple and incredibly accurate. The intermittent fasting timer is a great addition and I use it every day.

FAQ, the questions we hear most

The model recognises ingredients and estimates portions from more than 250,000 verified meals, reaching 90–96% accuracy. For comparison: dietitians eyeball it at 68–74%, and the average person at 48–55%. And when the AI does get it wrong, you correct the result in one tap with Fix.

In classic apps you search a database for every product, type in the weight by hand and end up with nothing but a calorie number (you can of course still add meals manually in Slim AI). Slim AI analyses the meal from a photo and, on top of macros, shows a Health Score: how the food affects your skin, bloating, mind, ageing and your vitamin and mineral levels.

Slim AI works on a subscription. The yearly plan costs less than one coffee a month and starts with a 3-day free trial you can cancel at any time, no strings attached.

Slim AI supports:

  • classic
  • keto
  • carnivore
  • vegetarian
  • vegan
  • pescatarian

Macros and recipes are matched to the eating style you pick, not calculated from one template for everyone.

For anyone who wants real results:

  • losing body fat
  • building muscle
  • staying on top of calories and macros
  • a quick, simple routine without the stress
  • checking how healthy your everyday meals and food choices are

If you want results rather than another app you drop in a week, Slim AI is for you.

Start today and change your body!

No counting calories, no planning fasts, no reading labels. Slim AI does it for you.
