New in FitZen 2.0: RoboFit and Calendar
FitZen is an AI calorie counter and food tracker. Photograph your plate and it estimates calories and macros in seconds. Then RoboFit, your AI nutrition coach, suggests what to eat next — based on your log, your goals and your health notes.
FitZen is a calorie counter and nutrition app for iPhone and Android that estimates calories and macronutrients (protein, carbohydrate and fat) from a photo of a meal. It is developed by Ali Mert Güleç in Türkiye and available in 11 languages. FitZen 2.0 adds RoboFit, an AI nutrition coach that reads your food log, goals and optional health notes, and a Calendar that keeps every past day with its meals, macros, water, workouts and fasting. The app is free to download: the free version includes 3 manual food logs and 3 photo scans, and FitZen Premium (weekly or yearly) unlocks unlimited logging and photo scans, RoboFit, AI diet plans, the fasting timer, fridge recipes and the weekly report.

Meet RoboFit
RoboFit is the AI nutrition coach built into FitZen. It sees what you have logged today, your calorie and macro targets and the health notes you choose to share, and it can look back at past days in your Calendar — so its answers are about your day, not a generic diet.
Get meal ideas ranked by how well they fit your remaining calories and protein.
Snap your fridge, a restaurant menu or a nutrition label and ask what fits your goal.
Suggestions respect the conditions and allergies in your health profile, such as diabetes, high blood pressure or PCOS.
Ask at any hour: swaps, portion sizes, eating out or what to put on your shopping list.
RoboFit gives general nutrition guidance, not medical advice. If you have a medical condition, follow your doctor’s advice.
New: Calendar
The Calendar keeps your whole history in day, week and month views. Tap any day to see every meal with its time and portion, your macros, water, workouts and fasting — exactly as you logged them.
Spot patterns at a glance: days on target, days over, logged streaks and your daily average.
Meals with times and portions, macros, water, exercise and fasting windows in one place.
RoboFit can read past days, so you can ask about any date in your history.
“RoboFit, what did I eat last Tuesday?”
How it works
Logging food is the step most people give up on. FitZen turns it into one photo and a quick check.
Open the camera in FitZen and take a photo of the meal. Mixed plates are fine: each food is detected separately.
An image model recognises each item and estimates its portion; calories, protein, carbs and fat are then calculated from nutrition data.
The result is an estimate, not a weighing. Change a portion, correct a food or remove an item with a tap before you save.
The meal lands on your Today ring and in your Calendar, and RoboFit can suggest a next meal that fits what is left of your day.
How accurate is it? Photo calorie counting is an AI estimate. It works best on clearly visible, separated foods and is less precise for dishes in sauce, stacked food or closed containers — that is why every result can be edited.
One photo, the whole plate
Every item gets its own calories and macros, so you can halve the rice or skip the sauce before you log.
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 a single photo, and RoboFit turns the numbers into a plan for your next meal — 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 is analysed by an AI image model that separates the foods on the plate and estimates each portion. Calories, protein, carbohydrate and fat are then calculated from nutrition data. Before you save, you can adjust any portion or correct a food it misread.
It is an AI estimate, not a weighing. It is most reliable for foods that are clearly visible and separated, and less precise for dishes covered in sauce, stacked food or closed containers. That is why an edit screen opens after every analysis: check the portions and you have the final say.
RoboFit is the AI nutrition coach inside FitZen (a Premium feature). It can see your food log, your calorie and macro targets and any health notes you choose to share, so you can ask “what should I have for dinner?” and get an answer that fits what is left of your day. You can also send it a photo of your fridge, a restaurant menu or a nutrition label. RoboFit gives general guidance, not medical advice.
Yes. The Calendar has day, week and month views. Tap any day to see every meal with its time and portion, plus macros, water, workouts and fasting. RoboFit can read past days too, so you can ask things like “what did I eat last Tuesday?”.
You can add conditions such as type 1 or type 2 diabetes, high blood pressure, high cholesterol or PCOS, along with allergies, to an optional health profile. Meal suggestions, recipes and RoboFit then take them into account. FitZen offers general nutrition guidance only: it does not replace your doctor, so talk to them about your diet, especially if you take medication.
Yes. The fasting timer (a Premium feature) covers 16:8, 18:6, 20:4 and OMAD, with streaks, and sits next to your calorie tracking. Your fasting windows also appear on each day in the Calendar.
There are 10 diet plans, including Mediterranean, keto, low-carb, DASH and paleo. With Premium, FitZen builds an AI 7-day plan for the diet you choose, and the fridge-to-recipe feature can give a vegan version of any recipe.
Your data is not sold. AI features only run after you agree: when you use them, the photo or text you submit and related profile data (such as goals, weight and dietary preferences) are sent to OpenAI for processing, and OpenAI does not use this data to train its models. Health conditions are shared with RoboFit only with your separate consent, which you can withdraw at any time. You can delete your account and all your data from inside the app.
The app and this website are available in 11 languages: Turkish, English, German, French, Spanish, Italian, Arabic, Indonesian, Japanese, Thai and Malay. Every recipe on this site is published in all 11.
FitZen runs on iPhone (App Store) and Android phones (Google Play). Photo analysis, RoboFit and other AI features need an internet connection. On iPhone, steps can be synced from Apple Health; step sync is not available on Android.
No. FitZen logs food from a photo of the meal or by manual entry. For packaged food you can photograph the nutrition label and ask RoboFit about it.
