Accessibility Service

The app features a series of alarm tasks called CAPCTHA which make sure you do not oversleep. Completing tasks like sheep counting, math equations or scanning a bar-code on your toothpaste will make sure you are fully awake and ready for your morning.

To make sure you won\'t sleep through your duties the app may use an Accessibility Service to prevent you from force stopping the app or turning off the device (cheating) before completing the alarm tasks (CAPTCHA). No private information are collected.

Device Admin

This app may use the Device Administrator permission.
The reason is effective CAPTCHA (a feature to make sure you wake up in the morning) so you cannot avoid alarms by uninstalling the app during an alarm.

Health disclaimer

Sleep as Android is not intended for medical use, but instead to improve general fitness and well-being especially in terms of better sleep. Any oxygen saturation tracking is performed with compatible oximeter devices such as the TicWatch 3 Pro, BerryMed oximeters... more at

Prior versions and newer versions available via the What's New release notes link. Customer service is very responsive. A+. All prefs and data backup to Google account plus you can export. But what you pay for today, can change tomorrow. It's a Play Store app so it can revert back to trial version which is annoying but fixable. I paid for Sleep as Android years ago because I thought it is pretty good for tracking sleep quantity and quality. They've expanded it and it's complicated looking now.

I got this specifically for the headphone output feature only. The issue is if you put it on gradual increase for a minute or more, whatever you are playing in the background immediatly goes max volume, so it's pointless, jarring deafening. I've been using the "use phone volume" and it works fine, but sometimes too quiet. Guess Ill have to try out other alarms. Too bad, because the other features are nice.

The app has great data but it's not intuitive. It shows you data and graphs when it comes to deep sleep, REM, light sleep and a bunch of other stuff including sleep efficiency. There's no benchmarks though so it's not easy to see how well you're sleeping compared to the average. Fitbit and Samsung have much more intuitive interfaces and you don't have to dive into a bunch of FAQs to figure it out. The smart awake alarm clock is also not available to set on the watch and only the app.

Hello Michael, there is a whole section dedicated to comparing your data with the community (your region, worldwide, or any country) - Left ≡ menu → Stats. The smart alarm works on the wearable the same way - you just need to configure the integration with the wearable and set a smart period for your alarms. More details at
