Calories
Per ingredient and for the whole dish.
Feature · Chat calorie tracking
Type instead of scrolling through databases. You write your meal like a quick text message, and Weekfuel turns it into an entry with calories, protein, carbs and fat.

In short
With chat calorie tracking you simply type what you ate into Weekfuel, for example “chicken with rice”. An AI breaks the text down into individual ingredients, estimates the amounts and calculates calories, protein, carbs and fat. You check the result, adjust it if needed and add it to your day with one tap.

“Chicken with rice” can be 400 or 900 kcal. It depends on how much rice is on the plate and whether the chicken was fried in oil. That's why Weekfuel lists every ingredient with its amount. You see at once where the calories come from and fix exactly what's wrong instead of re-entering the whole meal.
Per ingredient and for the whole dish.
Your macros feed into your daily and weekly totals.
Change amounts, remove ingredients or add details by message.
For packaged products the barcode is often quicker: scan the pack and the name and nutrition values come from the free food database Open Food Facts. No AI needed.
Only the text of your message is sent to an AI service for the estimate. Weekfuel does not send photos. Depending on load, models from Alibaba Cloud (Qwen) or Anthropic (Claude Haiku) are used. The AI service never gets your name, your weight or any Apple Health data. The finished meal is saved only on your iPhone. Details are in the app privacy policy.
As accurate as your description. With amount and cooking method the estimate is usually close; with “a plate of pasta” the AI has to guess. Treat the result as a solid starting point and correct what you know better.
No, Weekfuel works with text. A short message is quick to write, and you can add amounts or cooking method right away. For packaged food there's the barcode scanner.
It knows a wide range of cuisines, from tacos to carbonara. For very local dishes, give the listed ingredients a quick check.
The meal is then stored only on your iPhone. The text goes to the AI service for the estimate. What is processed there and for how long is described in the app privacy policy.
