Fuel is a free AI calorie and macro tracker. Instead of searching a food database, you type what you ate in plain English — for example 'two eggs and toast with butter' — and Fuel's AI extracts the calories, protein, carbs, and fat automatically.

How does AI calorie tracking work?

Fuel uses an AI language model to parse your plain-English meal description into individual food items. It estimates portion sizes and macronutrients based on that description, then adds structured entries to your daily diary. You can review and edit any entry.

Yes. Fuel's core features — food logging, calorie and macro tracking, daily diary, history, and daily diary reviews — are completely free. A paid Fuel Plus subscription unlocks meal planning, wearable activity sync, and higher usage limits.

Does Fuel work in the UK?

Yes. Fuel is primarily designed for users in the United Kingdom and uses British English throughout. It's available as a web app at fuelapp.uk and as an Android app.

Can I track macros as well as calories?

Yes. Fuel tracks protein, carbohydrates, and fat alongside total calories. You can set custom daily targets for each macro and see running totals throughout the day.

Does Fuel sync with Fitbit or Strava?

Yes, with a Fuel Plus subscription. Fuel supports activity sync with Fitbit, Strava, Oura, and Whoop to automatically import step counts and activity calories.

How accurate is AI food logging?

AI estimates are close approximations based on typical serving sizes and nutritional data. They are accurate enough for everyday habit tracking and are comparable to manual database lookups. All entries can be edited if you know the exact values.

How is Fuel different from MyFitnessPal?

Fuel uses AI to understand natural-language descriptions of meals — you don't need to search a database or scan a barcode for every ingredient. This makes logging faster and more conversational, especially for home-cooked meals and mixed dishes.
