features
Everything a food diary needs, nothing it doesn't
Personal food library
Save the foods you actually eat with their macros once, then log them in two taps. Your own shortlist, not a scroll through a global database.
Open Food Facts search + barcode scan
Look up packaged products by name or point the camera at a barcode — calories and macros fill themselves in from Open Food Facts.
TDEE goal calculator
A short wizard estimates your daily energy budget and splits it into protein, fat and carb targets. Tweak any number if you know better.
AI logging via the Claude connector (MCP)
Connect Calsheet to Claude and log by chatting: "two eggs and a slice of toast for breakfast" becomes a proper diary entry with macros.
JSON backup & restore
One tap exports your whole diary, food library and settings to a JSON file; restore it on any device. Your data is never locked in.
how-it-works
How it works
- Set your goal
Answer a few questions in the TDEE wizard — it turns them into a daily calorie budget with macro targets.
- Log your meals
Search Open Food Facts, scan a barcode, pick from your food library, or quick-add plain calories.
- See totals & stats
Today shows what is left of the budget; 30-day stats show whether the week actually went to plan.
