Know your debt.
Plan your recovery.

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. Your health data never leaves your device.

02

Set your goal

Set your sleep target and a wake time for each day of the week. Takes 30 seconds. Adjust any time in settings.

03

See your debt

Your deficit is calculated over a rolling 14-day window. Naps and manual entries count. Days without data are skipped, never counted as zero.

04

Follow the plan

A 7-day calendar shows the bedtime to hit each night to gradually clear your debt. Mark rest days, and let the bedtime reminder move earlier while you are in debt.

Features

Everything you need.
Nothing you don't.

Sleep Debt Balance
14-day rolling debt calculation from your Apple Health sleep. Naps are credited (capped per day), and manual entries always win over automatic data.
Free
Calendar Recovery Plan
7-day calendar with nightly bedtime targets and a debt-zero date. Per-weekday wake times and rest days. The first 2 days are free.
Premium
History & Trend Charts
7, 14, and 30-day views of sleep duration and naps for everyone. Premium adds Deep / Core / REM stage breakdowns and previous-period comparison.
Free + Premium
Heart Rate & HRV
Nightly heart rate and HRV trends from Apple Watch, with period averages, in the History tab.
Premium
Widgets & Apple Watch
Debt level, recovery progress, and tonight's bedtime on your Home Screen, Lock Screen, and Apple Watch complications. Medium widget is Premium.
Free (small + lock screen + Watch)
Morning Check-In
Optional, about 10 seconds: rate quality, restedness, and energy, then tag last night's factors — caffeine, alcohol, exercise, stress, late meal, screens, travel, sick.
Free · opt-in
Tag Insights
Compare tagged and untagged mornings: restedness, sleep duration, and deep-sleep share. See how caffeine or a late meal actually changes your sleep.
Premium
Summaries & Reminders
Morning summary, weekly summary, and milestone celebrations. The bedtime reminder shifts earlier while you carry debt. On iOS 26, the morning insight is generated on-device.
