Sleep Debt Log & Recovery Jar

Know your sleep debt at a glance — 3-day free trial of SleepDebt Premium unlocks everything.

SleepDebt is a clean, ad-free sleep tracker for iPhone — built for people who keep telling themselves "I'll catch up on sleep this weekend" and never do.

Most nights you sleep a little less than you need. SleepDebt adds up that shortfall so you can finally see it. Set your nightly target, log when you went to bed and woke up, and watch your sleep debt fill an animated jar. The more debt you carry, the fuller and redder the jar gets. Catch up on rest and watch it drain back down.

Key features:

• Animated debt jar — your accumulated sleep deficit, visualised. It fills as debt grows and drains as you catch up, shifting from green to orange to red.

• One-tap nightly logging — set bedtime, wake time, and a 1–5 star quality rating in seconds.

• 14-day debt calculation — your rolling sleep balance versus your target, shown as a clear surplus or deficit.

• Sleep target you control — adjust your nightly goal anywhere from 5 to 12 hours.

• Stats at a glance — weekly average per night and a consecutive-day logging streak.

• History tab — a bar chart with your target line plus a night-by-night list showing how each night landed against your goal.

• 100% local — built on SwiftData. No account, no network, no analytics, no ads. Your sleep data never leaves your device.

Privacy by design: SleepDebt collects nothing. No tracking, no ads, no account, no servers. All data stays on your iPhone.

SleepDebt is for you if: • You suspect you're running on a sleep deficit but have never quantified it. • You want a dead-simple sleep log, not a clinical sleep lab. • You care about a beautiful, focused app that respects your time and your data.

PREMIUM Unlock everything with a 3-day free trial, then an affordable subscription — cancel anytime. No ads, no tracking; your data stays on your device.
