Scan it. Track it. Grind on.
Point your camera at a barcode or a nutrition label — The Protein Grind reads the macros, tracks your day against your targets, and tells you when to restock. Free, installable, and works offline.
Features
Everything you need to track what you eat
From the supermarket shelf to your daily total — in a few taps.
Barcode scanning
Scan with your phone camera (works in iOS Safari), or type a barcode by hand. Names, brands and nutrition come straight from Open Food Facts.
AI label reading
Snap a nutrition label and a vision model reads the per-100 g values for you — in any language. Prefer free and on-device? Switch to OCR in one tap.
Calorie & macro targets
Set a quick fitness profile and see your day vs. target — calories plus protein, carbs and fat, with sugar and salt limits.
Pantry forecasting
Track what's at home and tap “Use 1” as you go. The app learns your pace and flags what to restock before you run out.
My Foods & custom items
Everything you scan is saved to a searchable list, and you can add homemade meals or anything not in the database — with an estimated Nutri-Score.
Optional cloud sync
Sign in with a magic link to sync foods, favorites, pantry and journal across devices. No account? Everything stays on your device.
Daily journal
Log by the gram, the piece or the pack. Totals scale to the portion and reset at your local midnight.
Installable & offline
Add it to your home screen as a PWA. The interface is precached, so it opens instantly even without a connection.
How it works

Point at a barcode, or snap the nutrition label for anything not in the database.
