AI-powered nutrition coach
NutriOS recognises every dish in the photo one by one, estimates the portion in grams and pulls calories from a verified database of 212,747 foods instead of guessing. All you do is take the photo.
Try it
In the app you take the photo; AI turns every dish on the plate into its own item and pulls the calories from the database. See the same flow with three sample plates below.

Photo recognition is in Premium; barcode and search are free.

Your goal
Pick your goal; in a few questions we work out your daily calories, macros and goal date. The same formula the app uses.
01 · AI Camera Premium
The in-app camera opens with an alignment frame; everything outside the frame is cropped, so only the plate reaches the AI. The model reads every dish on the plate as a separate item and estimates its portion in grams.
The AI gives the name and the portion of the dish. Calories and macros are pulled from the database. For the rare item with no match an AI estimate is used, and the card says so plainly with an AI estimate tag.
If there are two bagels in the photo the item is not duplicated, the count is multiplied by the grams. If a whole product is visible, no half portion is guessed; the full weight is written.
If an allergen from your profile shows up on the plate, the item is not dropped from the list, a warning is added on top of it. An empty allergen list does not mean “allergen free”, it means “none detected”, and the app writes that out too.
Every item has a “not this one?” picker next to it: it searches all 212,747 foods and keeps the grams you entered when you pick another.
02 · AI Meal Plan Premium
Your target calories, diet style, meal count and the allergens in your profile are read; the AI builds a week of meals. Tap a meal and its recipe, ingredients and method included, is written right there and then.
Your daily calorie target comes from your profile. You pick your diet style and how many meals you eat a day; your allergies are already saved in your profile, no need to type them again.
The target calories are split across the day and the meals. The day’s total is shown next to the target: 2,222 kcal against a 2,217 kcal goal in this example. The same choices are never placed on consecutive days.
Ingredients come in grams, the method step by step. The moment you say “I ate this”, calories and macros go into the daily total; you never write it twice.
Recipe nutrition values are estimates produced for that recipe; they do not come from the verified data set. The app states this under the recipe too.
03 · Personal AI Premium
The AI reads your remaining calories, your macro gap, your goal and your diet style; it writes what it suggests and why it suggests it. Every meal it picks comes from the verified food database; it is not a made-up list of dishes.
✦ AI“While your energy is high I leaned towards options that keep you fuller and watch the fat balance, so your weight-loss goal is supported with protein first. Within the remaining 1,717 kcal you can focus on closing the protein gap in particular.”
A real rationale generated inside the app
Once your daily target is met the suggestion card closes itself. When you go over, the excess is written in red and the percentage is not clipped. You see the real state.
There is a thumb next to every suggestion. What you dislike never comes back; what you like moves to the front.
The app writes this under every AI card. Suggestions are nutritional support; if you have a chronic condition, talk to your doctor.
04 · Learning
Nutrition knowledge does not sit in the app as a list. 546 knowledge cards and 546 “common myths” are locked behind step thresholds: each threshold opens one card and one myth. Walking is the key to learning.
Hover a card to flip it over. Tap a card to flip it over.
The myth: bananas, grapes and figs are so sugary that they are off limits while losing weight.
The truth: no fruit is banned; what matters is total calories and portion size. These fruits carry potassium, fibre and antioxidants.
The myth: desserts and drinks labelled sugar-free can be consumed freely.
The truth: these products can still hold fat, starch, sweeteners and calories. “Sugar-free” does not mean “low calorie”.
The myth: olive oil breaks down when frying and turns carcinogenic.
The truth: the smoke point of extra virgin olive oil is high enough for home frying and it stays stable; its antioxidants tolerate heat.
It is needed for blood clotting and bone health. The richest sources are dark leafy greens: spinach, kale, broccoli.
The WHO recommends keeping total fat below 30% of daily energy, saturated fat below 10% and trans fat below 1%.
Yes. Soy is one of the rare plant sources of complete protein, holding all essential amino acids; it is eaten as tofu, edamame and soy milk.
What the cards taught you turns into a small question the next day. It takes less than a minute.
Which one is a complete protein source?
05 · In the box
Your weight × 0.033 L is the baseline; gender, season and activity level are added on top. The app shows the calculation openly; it does not hand you “some number” of litres. 200, 250, 330 and 500 ml go in with a single tap.
Scan a packaged product and its card appears at once. Barcode scanning is free; the catalogue lives on our own server, no outside service is asked.
Turkish cuisine is its own set. Fibre and glycaemic index included; search forgives typos.
The score is calculated deterministically; the AI only writes the commentary. Weight history and your weakest area arrive together.
Change your phone and the log stays. What you write offline queues up and flows once you reconnect.
A curated dictionary. “Gluten-free oats” does not trip the gluten filter, and a partial word match never raises a false alarm. An empty list means “none detected”, not “allergen free”.
At 100% it says “target complete”, past it the excess is in red. Once the target is met the suggestion card closes itself.
Every screen feeds from a single palette and follows the system theme. Interface and notifications are in Turkish and English.
Barcodes, water, steps and knowledge cards are free. Log your first plate tonight.

Classic counters make you search every bite by hand; scanners that rely on AI alone guess the calories too. NutriOS sits between them: AI recognises the dish, the number comes from a database.
| Feature | NutriOS | Classic counters | AI-only scanners |
|---|---|---|---|
| How is a meal logged? | Photo, barcode or search | Mostly manual search | Photo |
| Where do calories come from? | The database; estimates are labelled | Entries typed by users | The model’s estimate |
| Turkish & Mediterranean food | A separate cluster of 39,300 entries | Entry quality varies | Often trained on Western dishes |
| Barcode scanning | Free | Only in the paid tier of some | With a subscription |
| Usable without paying? | Yes, core tracking is free | Yes, limited | Most show a paywall after setup |
A comparison of general approaches; apps can change their features.
