Sleep Debt Tracker Calculator

About this app

Track your sleep debt and see exactly how many hours of rest you owe. Log last night, and the app turns every short night into one running number — plus the plan to pay it back. Most sleep apps only show you last night. SleepDebt keeps a rolling 14-day balance: every hour under your personal sleep need pours into a visual jar, and every long night drains it. Instead of a vague "you slept 6h", you get an answer to the real question — how far behind am I, and how do I get even? No account, no sign-in, no wearable required. Set your nightly need, log bedtime and wake time in seconds, and start tonight. WHAT YOU GET - One clear number for how much sleep you owe, updated every night - Tonight's target bedtime, adjusted to chip away at your debt - A recovery plan that says how many nights and how long to sleep to reach even - A 14-day debt curve and sleep-duration chart so you can see the pattern, not guess - Deeper insights: sleep consistency, day streak, best and worst nights, average quality - A bedtime reminder at the hour you choose, so the wind-down actually happens PERFECT FOR - Shift workers and on-call staff whose schedule keeps moving - New parents counting the hours lost to night wakings - Students and night owls trying to bounce back after a run of late nights - Anyone who feels tired all day and wants to know why, in numbers WHY NOT JUST USE A SLEEP TRACKER OR A NOTES APP? A sleep tracker tells you last night's total and stops there. A notes app never adds anything up. Neither one carries the shortfall forward, and that carry-forward is the whole point of sleep debt — miss an hour on Monday and you're still down that hour on Friday unless you repay it. SleepDebt does the running math, keeps a 14-day balance, and turns it into a bedtime you can actually hit tonight. PRIVACY Every night you log stays on your device. No accounts, no ads, no tracking, nothing sent anywhere. FULL ACCESS Logging your nights, your sleep debt total, tonight's target bedtime, bedtime reminders and the Learn library are free. Full access unlocks the 14-day debt trend and duration charts, your personal recovery plan, and deeper insights (consistency, best and worst nights, debt patterns). Choose a weekly subscription, a yearly subscription, or a one-time lifetime unlock — the exact price is shown before you buy, and you can restore a previous purchase any time. This app is a wellness and self-tracking tool to help you understand your rest. It does not diagnose, treat, or replace professional medical care. Log last night's bedtime and wake time right now — you'll see your sleep debt and tonight's bedtime in under a minute.
