Accessibility Service

The accessibility service is necessary for a series of alarm tasks called CAPTCHA. Completing tasks such as sheep counting, doing math, or scanning a barcode on your toothpaste will ensure you get up on time and are fully awake.
The accessibility Service prevents you from cheating the CAPTCHA tasks by force-stopping the app or turning off the device before completing them. No personal information is collected.

Device Admin

This app may also use the Device Administrator permission to prevent you from cheating CAPTCHA tasks (see above) by uninstalling the app.

Health Disclaimer

Sleep as Android is not intended for medical use, but rather to improve general fitness and well-being, especially in terms of better sleep. Any oxygen saturation tracking is done with compatible oximeter devices such as the TicWatch, BerryMed oximeters... more at https://sleep.urbandroid.org/docs/devices/wearables.html

Been using sleep as android for several years now and never would I get rid of it or use another service. That's not to say perfect, but the support team is fabulous & quick, if they can't fix the issue, they will eventually! OR, your devices are simply too old which is what my issue has been b4! W/ my phone and my watch. Now it actually tracks all night long! Great app, great features, accessories, etc! These developers are some of the best people I don't know! 💜 😅 Thanks! ✌️

Hello Jamie, if the tracking stops during the night, the app is probably killed by one of Samsung's "optimizations". Please, visit https://dontkillmyapp.com/ guide and disable these optimizations for the Sleep app. The DND usually does not apply to alarms, only calls and notifications. Could you please contact support@urbandroid.org?

I've been using Sleep as Android for over a decade now. No other alarm app comes close. As a heavy sleeper, the CAPTCHA options to turn off an alarm are invaluable. Mine is set up so I have to scan an NFC tag in my bathroom before I can dismiss an alarm, forcing me to get out of bed. Otherwise I can dismiss an alarm and never even remember. Love this app!

Catching the Sleep as Android yearly premium sale was an absolute steal! For just a few bucks, you unlock an insane amount of features like smart alarms, cloud backups, and deep sleep tracking without even needing a wearable. It is inexpensive, incredibly reliable, and a must-have deal that completely upgrades your nightly routine. I use it every single day and it is worth every penny. Highly recommended!
