I have found this app really useful and very feature rich. I use it to turn YouTube off so that videos aren't playing when I'm asleep. There are lots of options to turn app on at certain times or when certain apps are opened, etc. Yes, there is an ad when you open it, but that is it other than an unobtrusive banner ad. To get access to all the features and remove the ads, I found the cost to be very reasonable. Here's hoping that the developer keeps the app updated and usable for a long time.

It works, every time, and it is easy to set. Fit for purpose is the highest measure of quality.

The best sleep timer on Google Play, it does what it's supposed to do, and the app has a lot of features. 10/10
★★☆☆☆Robert Stang· Mar 24, 2024
Worked great for turning off the screen and media on a timer but recently has not been working correctly. Screen turns off but sound continues well past the timer even with close app settings enabled, YouTube and Netflix both lower volume then go back to full volume and keep playing with screen off. They only stop playing when the app "are yours till there" pauses the play. Ads causing a shift in Windows and menus became annoying as well.

Ads are weak AF. Shame on Android for not including a free sleep timer for audio.

It doesn't turn off Bluetooth anymore! I literally paid for premium because I loved the app so much, it was perfect otherwise. Now it can't turn off Bluetooth which is very annoying.
★☆☆☆☆Emily Mozdzen· Feb 16, 2026
I've been using this app daily for years, but the ads are getting to be too much that I will be deleting it and using another app. I listen to shows to fall asleep and use this to shut them offhand the last thing I want in the middle of the night is to sit through a bright 10-second ad before I can access the timer. No, thanks.
