How it works

Four steps.
One honest score.

No guesswork. Just your real sleep data, a precise debt calculation, and a nightly plan to get out of the red.

01

Connect Health

Grant read-only access to your Apple Health sleep data. One-time setup. Nothing ever leaves your device.

02

Set your goal

Set your sleep target and typical wake time. Takes 30 seconds. Adjust any time in settings.

03

See your debt

Your deficit is calculated over a rolling 14-day window. Apple Watch users get quality-weighted scoring using Deep, REM, and HRV data.

04

Follow the plan

A 7-day calendar shows the exact bedtime to hit each night to gradually clear your debt — with weekend catch-up support.
