How it works

Three taps a day — and a few clever things under the hood.

1. Photograph or say it. A photo of the plate, a voice message or a few words: “a sandwich with butter and coffee with milk”. You can also just send a photo to the Telegram bot. Packaged food has a barcode, restaurants have a menu photo.
2. Hroomy figures it out. It recognizes the dish, the ingredients and the portion, then counts calories, protein, fat, carbs, fiber and micronutrients (iron, calcium, vitamins D, B12 and C, omega-3, magnesium, zinc).
3. Get simple advice. Not “+30 g protein” but “add 2 eggs or 100 g cottage cheese”. The advice takes into account your allergies, eating style, what you have at home, cooking time and budget.

Where the numbers come from

AI (the Claude model from Anthropic) recognizes the dish and its ingredients, but numbers come from food databases: USDA FoodData Central and Open Food Facts. This is more accurate than asking AI to “guess the calories”.

• If most ingredients are found, the numbers come from the database and are marked “from the food database”.
• If the match is approximate (for example “chicken” instead of “chicken breast”) we lower our confidence and say it is an approximation.
• Oil, butter, sauces and sugar carry many calories in a small portion, so without an exact match we do not pretend to be precise and keep the AI estimate with a note.
• If there is no data about a micronutrient we say “not known yet” instead of counting it as zero.

How advice is made

The “right now” advice is calculated by a deterministic algorithm (no AI, so it is free and instant):

1. We look at what is missing today — but only when the data is reliable enough. If most entries are rough estimates we do not announce “deficits” but recommend variety.
2. We filter out everything that does not suit you: allergies, eating style, “I don’t eat”.
3. We try simple food combinations and pick the best one: what covers the need, what you already have at home, inexpensive, quick, new today, not eaten just now.
4. We show one option and the “Another option” button shows the next. You can answer “Did it help?” and Hroomy will stop suggesting what does not suit you.

A week without guilt

Once a few days have accumulated, “Your week” shows your eating rhythm: averages over complete days, what repeats, one small change. A day counts as complete when you marked it “That’s everything I ate today” — so a skipped lunch does not become “normal”.

What happens to your data

• A photo is passed to the AI only for the time of recognition and is not stored by us — only the analysis result remains.
• Your name and email are not sent to the AI.
• Everything can be downloaded as one file or deleted together with your account.
