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!

Actually the best auto off app I honestly use this every night to have my phone shut off by itself. You set a timer for when you want the phone to shut off, and then you can do whatever you want on the phone, and it'll shut off when it's supposed to. Has settings to adjust what you want the phone to do (shut off, turn off wifi, mute, etc) Super simple ui, and just all around a good app. Does what it's supposed to
