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

Can't even open it. Crashes immediately. Reports are inaccessible (only option shown is to send an email, but says "unable to add attachment"), so I don't even know why. I suppose it's due to root detection? If that's the case, that's ridiculous. All other apps, including wallet, banking etc. work. This is just a glorified alarm... Why would it need such aggressive root detection?

Hello Rosario, if the app cannot even be opened, it is highly probably corrupted installation. Could you please send us more details to support@urbandroid.org? We do not have any other similar reports. How long has this been happening for you? How long have you been using the app (approximately)?

The OG of all Sleep Trackers, "Sleep As Android" is one of the first Android apps in that genre I remember. I feel like it has been around forever, and it shows: Solid, feature-rich design, surprisingly up to date with adaptive frameworks. It's become my favorite alarm clock by far. And when I'm not using my daylight therapeutic lamp, or when I'm travelling, it's my only alarm clock.... Huge respect to one of the only remaining - original - old school Android apps. That's the way I like my tech!

I've been using this app a lot as my alarm, as it offers more than the default clock and i can also make it ring only through my headphones. It works well and is fairly intuitive. Though in recent times the Ads have been ruining it for me, as they will always play with Volume on first. I usually don't mind Ads as the app is great even for free, but setting up an alarm late at night just for some Ad to play full Volume and jumpscare me is the biggest problem I have with it.

Hello Vic, we only show interstitial ads after a long time without any purchase, but as per your report and a new policy, we won't be showing them if the app is in Alarm ONLY mode. Would that address the issue for you? Please let us know at support@urbandroid.org. Thank you.
