Ratings and reviews

Really like this app. For whatever reason it's been difficult finding something the properly stops video playback and not just music/sound. Works very well and was easy to use. Has a bunch of neat options to customize like gradually decreasing volume, a 'snooze' button to add more time, turn off bluetooth/wifi/data, etc. Used it a couple times and paid for the full version pretty quickly. Free version worked well too, ads weren't obnoxious at all. Well worth the couple bucks for me.

This app is pretty great, I've used it for quite a while and it's really useful. Easy to use and I like that you can set it to auto open your chosen app/s. There is one flaw - I use dark mode and tend to use this app late at night. I don't mind adverts but the initial advert is bright white and blasts my eyes - if possible a dark mode advert would be helpful!

It's a very helpful sleep timer for apps that dont already have a preset one. I use it often for netflix or YouTube to turn my phone off after 45 minutes so it doesn't run all night. It helps a lot for the Samsung health app to accurately track my sleep. I haven't had any issues with the app so far and I've been using it for a little over a month.
