Edit: Excellent. Now i don't have wait for my homescreen to reload icons, after exiting a heavy app like clash royale. It stopped working after a day or two. I think this app wants me to buy pro. Too bad, uninstalling.
Do not buy. This app seems to work fine, but when I had to reset my phone I could only install the unpaid version. You're supposed to get a license key by email, which I never received. App creator won't respond to emails, I've tried to contact him 5 or 6 times with no response.
Other applications or none at all do better than this garbage. It had the opposite effect and caused me to loose a multiplayer gaming tournament.
Location permission, contacts permission... Really? Also the app freezes at loading, nothing happens, even with root perm. (7.1.1)
It really works: I locked four applications I do need to keep running and there they stay. No root!
This app does nothing. Apps still get closed including this one
