DotSleep - Sleep Debt Log
Fatigue Tracker & Bedtime
Free · In‑App Purchases
DotSleep helps you understand your real energy state and make better sleep decisions — not just by counting hours, but by tracking your cumulative sleep debt, fatigue score, and nightly recovery quality.
Fatigue Score, Sleep Debt, and Sleep Score
DotSleep uses a sleep debt based fatigue algorithm to estimate your current fatigue level, calculate your sleep debt balance, and show a Sleep Score that explains how well each night supports recovery.
Personalized Bedtime Suggestion
Based on your fatigue level, sleep debt, target wake time, and sleep latency, DotSleep gives you a personalized bedtime suggestion each night so you can recover proactively.
