Units You Can Log In
g · kg · ml · l · tsp · tbsp · cup · oz · lb · fl oz · gal · pinch · small/medium/large serving
The dropdown shows the gram equivalent next to each unit for the specific food you’re logging, e.g. “cup(142g)”.
Good to Know
- All your data stays on your device — nothing is stored on a server Eatalyze controls.
- You need your own free Gemini API key from ai.google.dev to use AI features.
- If AI is temporarily unavailable, you can keep logging normally — everything catches up automatically once it’s back.
- Dates in the future can’t be selected — there’s no data to show yet.
