SleepDebt connects with your Fitbit to analyze your sleep data and debt. Set what time you want to wake up and how many hours of sleep you are aiming for per night, and the site will let you know what time you should go to sleep. Each night, it helps you catch up on your sleep, until you clear your sleep debt. We encourage you not to try to catch up all at once, so the site will only recommend 30% of your sleep debt at a time. Catch up on your sleep finally!
