Common questions about the app
A product is not found
Grammo uses the open Open Food Facts product database. If an item is missing, add it manually — the per-100 g values from the packaging are enough.
Setting up widgets
Press and hold the lock or home screen, choose "Edit" → "Add widget" and pick Grammo. While logging, the Live Activity also shows your rings in the Dynamic Island.
What is in Grammo Pro?
Real energy expenditure from your own logs and weight trends, progress projection, weekly, monthly and quarterly reports, plus CSV export.

Where is my data stored?
