How it works

Three things. That's it.

No spreadsheets. No guilt. Just a small ritual you can keep.

01

Scan it

Snap your plate. YUMI reads what's on it and counts the calories — no menus, no math.

02

Speak it

Or just talk. "Two eggs and a flat white" — YUMI logs it, splits the macros, done.

03

Track it

Snap it, say it, or log it — YUMI will take care of the rest.
