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?

Bedtime widget is useless. If I wanted to know the time of the next alarm I'd use that widget instead. The bedtime widget is the only reason this app was recommended to me and it doesn't actually show the countdown Opening the app shows the bedtime countdown next to the alarm, so it's there, but I want the widget to do what it's name says. Also couldn't dismiss the tracking requests. Only option is to accept or just pretend it's not there. Uninstalled, the search continues

Hello Ryan, the bedtime widget shows a countdown till your bedtime. After bedtime, it shows the alarm time. What should the widget show after bedtime to make it less useless for you? The tracking can start automatically or manually (depending on your settings). What was the tracking request, that was not possible to dismiss?

Very customisable app. I only use it for alarms and sleep recording but there is much more available. I like the alarms as you can Skip Next with one click as opposed to remembering to reset your alarm after a bank holiday for instance. The Sleep Monitor is interesting even though mine never registers when I wake in the night for a pee no matter how close it is to my pillow. It's useful to be able to look back over bed times & sleep durations to assess how much sleep you need though.
