AI-powered nutrition tracking
No weighing, no scrolling through food lists. Photograph your plate — FitZen identifies what’s on it, works out calories and macros, and logs it toward your daily goal.
FitZen is a mobile nutrition app that calculates calories and macronutrients from a photograph of a meal. It is built by Ali Mert Güleç in Türkiye and runs on iOS and Android in 11 languages. Alongside photo analysis it includes an intermittent fasting timer, a smart kitchen that generates recipes from what is in your fridge, and an AI nutrition chat.
How it works
People quit food tracking for one reason: logging is tedious. FitZen removes that step entirely.
Open the camera and shoot. On mixed plates it separates and identifies each food.
Foods and estimated portions are recognised, then calories, protein, carbs and fat are calculated. Anything that looks off, you correct with one tap.
The meal lands in your diary. Calories, macros, water and steps build up on one screen so you can see your week at a glance.
How many calories is that burger, really?
Eyeballing it is usually off by hundreds of calories. Take the photo and stop guessing.
Inside the app
Daily tracking, fasting, recipes and coaching in one place — all in 11 languages.
Photograph the plate and let the foods and portions be identified. No barcodes, no searching through databases.
Your daily calorie target, your protein–carb–fat balance and your meal history on a single screen.
16:8, 18:6 or your own schedule. Track fasting and eating windows and keep your streak alive.
List what’s in your fridge and get a recipe that fits your goal, with calories and macros already worked out.
Ask anything: swapping a meal, building a shopping list, what to order when eating out. Answers use your own data.
Water intake and step count sit alongside your nutrition data, so you see the whole day in one view.
Why it’s different
In a classic calorie app, logging one meal takes minutes. Two weeks in, most people stop. FitZen gets logging down to three seconds, because the only plan that works is the one you actually keep.

I used to get so bored of eating the same things while dieting. Finding different, easy recipes in this app made it much easier to stick with it. Whatever I feel like, something suitable always turns up.

Your photo goes to a vision model. It separates the foods on the plate, estimates the portion using reference objects and plate size, then pulls calorie and macro values from a nutrition database. Before you confirm, you can adjust the portion or correct any food it misread.
Accuracy is high for foods that are clearly visible and separated. It gets harder with dishes buried in sauce, stacked on top of each other, or in closed containers. That is why an adjustment screen opens after every analysis — the estimate is a starting point, and you have the final say.
