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

have been using sleep as android for almost 10 years if not longer. it has been a great app. I have had my share of minor issues, almost all related to the learning curve, which is acceptable when you want something custom and when there are many options like there are here. in the last month since I have switch phones, it has become entirely unreliable. I have had 1 good week WHERE THE ALARM MADE SOUND. I thought I finally resolved the issue and chalked it up to my own mistake. It was not.

Hello John, could you please send the application logs by using the Left ≡ menu → (?) Support → Report a bug? Does the alarm work, if you set it in the next minute? Are the optimizations disabled for the app?

Shows you your movement patterns but as soon as you click stop and save you can never see this again. Also the app thinks my sleep duration was 5 hours, but at absolute most I had 2 hours sleep. The rest was being thoroughly uncomfortable and unable to sleep and the movement chart showed this, but the others do not. Not a generous review, but that's what happens when I have 2 ,hours of sleep.

Hello Ryan, the behavior of the app after saving the tracking depends on your configuration of Morning screen. All the graphs are also available in the list of graphs (Left ≡ menu → Graphs), and you can see your last graph on the Graph card on the main screen. You can increase awake sensitivity in Settings → Sleep tracking → Awake detection.

I actually love this app so much: It records my sleep, let's me listen back to every sound and the alarm verification is so smart. A notification appears a short while after you've dismissed your alarm. If you don't click onto the notification then the alarm will play again. You can turn this feature on/off. I prefer it since I always turn my alarms off and fall back asleep.
