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.

** CAN YOU FIX ALL UR APPS!!!!!!!! We seem to have an issue with all the apps, since the update to Android 14 nothing is working. This is on the older Chromecast with Google tv devices only, the message reads: “ failed to load local host/***.*.* (port 55555) from ***.*.*.* (port 5000ms: disconnection failed ECONNREFUSED (connection failed ) IF U DONT FIX THEM REFUND EVERYONE ON ALL APPS. THIS IS UNACCEPTABLE.
