I really like this app of course you can go in and individually close all the apps but this is more convenient. this app allows me to keep my my Android box running smoothly and I really don't have to worry about it .

Does work good. I suspected apps were running in the background of my ONN 4K Pro but was surprised to see how many using this app. One thing that appears to be missing which would be good to add is an automated kill apps function. So you don't have to go into the app every time.

Great app. It works. But once you close app with this app, the permissions will be set back to default, so you have to re-enable it. For example, I close app mouse toggle with this app and startup up again; and the permissions in accessibility was turn off and for some reason keep switching off even when I enable it. It was until I clear app data then it began to work again.

You can now use the new whitelist feature so apps like Mouse toggle / VPN etc will not be terminated by my app. Appreciate your support.
