I just don't really like anything that puts so many 100+ (duplicated) files and folders on your device. They should probably be shared and explained such as 'Permissions' are. Uninstalled.
Packed with features but kills the phone on reboot I understand that the developer needs money, but to charge your customers for the option to turn off a forced cleanup on reboot that makes the phone unusable for 15 minutes is an inconvenience, to say the least. The app is as good as ever apart from that.
This is literally the number 1 tuning app for Android, particularly as a rooted user. Remove ads from apps, hack out wakelocks, disable specific app sub-services.. it's fantastic. The only things I wish it had was the option to view startup events by category like the other app on the Play Store called "AutoStarts" and the ability to filter in the App config tool based on a component being checked\unchecked.
Allows you to turn up and force cpus and gpus to max power at all time wich helps with but is dangerouse
