How it works

From a plate to a clear picture in four steps.

01 / Capture

Log it the way you remember it.

Type a few words, say it out loud, snap the plate, or scan a barcode. Portions like katori, roti, or glass are understood.

02 / Review

See what’s inside, then fix anything.

Every meal opens into items with protein, carbs, and fat. Values are estimates, so editing an item or portion is one tap away.

03 / Progress

Know where your day stands.

A calorie ring, macro bars against WHO ranges, and a streak that rewards showing up — never restriction.

How Luna is different

Honest numbers. Kind design.

Tracking food should inform you, not judge you.

Estimates you can correct

Nutrition values are estimates, and Luna says so. Adjust items, portions, or macros in a tap.

Evidence over trends

Default ranges follow WHO population guidelines, with the reminder that needs vary.

No shame, ever

No “bad foods”, no cheat days. Streaks reward showing up, not restriction.
