A package already knows its numbers, so there is nothing to guess: the barcode is looked up in the open food database, and the only thing left to say is how much of it you ate. This path costs no recognition — it is a lookup, not a guess.
Before you start
You need the chat with the bot and a package with a readable barcode. Wipe the film, hold the code flat and fill the frame with it: a bent code on a soft bag is the one that does not read.
Step by step
- Open the chat with the bot in Telegram.
- Photograph the barcode on the package and send the picture.
- The bot names the product it found and asks how much.
- Tap an amount. The whole package is one button when the package weight is known; the rest are the usual portions.
- Or type the amount instead — a bare number in the next few minutes counts as grams of that product.
The entry lands in today, in the meal that fits the time of day, with the numbers from the database for the amount you chose.
If the product is not found
Not every package is in the open database, and an own-brand one often is not. Then the photo goes the ordinary way: send a picture of the food itself, or say it in words — «yoghurt, 150 g» — and correct the numbers from the label if they differ.
What the label does not say
The database holds what the package prints: per 100 g, and sometimes per portion. A product sold by the piece has a weight you have to add yourself, and a package you did not finish is the amount you ate, not the amount printed on it.
