Log food and macros

Track enough to learn something, without becoming a barcode monk.

Add what you ate

Open Nutrition, choose a meal, then search, scan, or reuse a recent food. Select the serving that matches what you ate and adjust the quantity.

Check the label when packaged-food data looks wrong. Products change, serving sizes vary, and databases are not immune to nonsense.

Add food screen with a search bar, AI photo scan, barcode scan, quick add, and custom food options.Food search results for banana showing calories, protein, carbs, and fat for each result.
Search, scan a barcode, snap a photo, or quick-add plain macros. Every result shows its macros before you log it.

Use the daily totals

Your daily view shows calories and macros against your targets. Treat the targets as guidance across time, not a pass-or-fail exam at midnight.

Consistency matters more than manufacturing perfect numbers from rough portions. Log honestly, notice patterns, and adjust when the trend calls for it.
