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

I've been using this for over 10 years now and still love it. My only issue is that an update or two ago, it became much more difficult to edit a playlist made of music on my phone. One of my music files in a 12 song playlist is broken, and I can't just edit it to remove it. EDIT: No, using the File icon under Playlist will only let me choose 1 song, even if I long-press to try to choose multiple, and then shows it under Song not Playlist.

Hello Nina, we support Android playlists, if you have the playlist created in m3u format, you can pick it as the ringtone.

Sleep as Android is one of the best paid-for options out there. Free trial to test, trends, options, multiple ways to track sleep even without having the phone nearby, and so on. The free version allows sleep tracking, but no trends, however (Sleep Tracker by Leap Fitness has trends for free, and Sleep Calculator). That being said, I don't completely trust the accuracy of any app that doesn't connect to heart rate and oxygen sensors. Also, it failed to pick up some noises, like me test talking.

Hello Josiah, the SpO2 and HR data depends on the wearable - not all wearables allow reading SpO2. Which wearable exactly do you have? If you have troubles with sound recording, please use the Left ≡ menu → (?) Support → Report a bug, and send us your application logs. Thank you.

Used to be a better app. I like to fall asleep to a podcast, and now the app will record that sound in its entirety as "sleep noise". Also the sleep tracking screen doesn't come up when I unlock my phone in the morning, so I forget it's even running. I wish this formerly excellent app would become excellent again. I even sprung for the paid version, it used to be so good. Would not pay for the app in its current state.

Hello Reecy, there were no changes in the sound recording for over a year - how long have you been having this issue? Could you please use the Left ≡ menu → (?) Support → Report a bug? Only alarm screens are eligible for Lockscreens on newer Android versions. Do you use automatic tracking, so the app can automatically end the tracking for you?
