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

Great app. Excellent for heavy sleepers. After using the free version I loved it so much I bought the app. I've used it for the last 3 years. The captcha is great for heavy sleepers. I used to set multiple alarms and was still late. The added features don't let the alarm turn off until you complete the task. It's amazing. Worth every penny and then some.

Really like the app, but hate the sleep notification. My phone will beep/vibrate excessively, and selecting stop doesn't always work. I'm forced to select stop repeatedly in notifications until it's accepted, but then it returns minutes later for more of the same. Literally, I had to turn off my notifications one night because I could not stop the sleep notification. Otherwise, good app but please fix the notifications issue.

Hello John, could you please send us you log (ideally right away after the notification misbehave - Report a bug from Left menu)? We would like to find the reason and fix it. Many thanks and big sorry for the troubles.

Loved the app, but when I bought the unlocked version back in 2019 I remember it including the extra lullabys as well. Now those have been stripped out and added to another add-on you have to buy. Shady practices to remove something people already paid for and try to get them to buy it again... I used to have access to bunch of the other lullabies, like fan (my favorite) and pink and brown noise, but now I just have access to the base 10 that come with it.

Hello Charles,nothing has changed in the paid vs. free content in the past 10 years,the Lullaby addon has been paid(and not a part of Sleep main app) since 2013. If you had the Lullaby addon purchased in the past - just install the Lullaby addon from Play Store.When you purchase premium version of Sleep as Android you get several lullabies for free
