What is new in Fettle. Newest first. Fettle is free and updated often.

10 July 2026 — Premium-grade features, still free

Sleep tracking. Log your hours and how you slept, and watch the trend on the Progress tab.
Custom macro split. Set your own protein, carbs and fat percentages, not just the presets.
Serving quantities. Log "2 slices" or "1 medium egg", not only raw grams.
Micronutrients. Fibre, sugars, saturated fat and salt now show for foods and as a daily total, pulled from Open Food Facts.
Scan a nutrition label (beta). Point your camera at the label on the back of a pack and Fettle reads the per-100g values for you to confirm.
Water tracking and quick add calories for when you do not have the food to hand.
Better food search. Branded UK supermarket items surface reliably now, even when the food database is having a wobble.
19 plain-English guides to calories and macros, at /guides.

Free calorie and macro tracker: a day diary with a calorie ring and macro bars, UK supermarket food search, barcode scanning, personalised daily targets, a weight trend, and a JSON backup. No account, no ads, and your data stays on your device.

End-to-end encrypted sync across your phone and laptop, with no account. Your data is scrambled on the device first, so only you can read it.
