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.
The right tool Recommended
3c system tuner Awesome app!
Used to be great Fails to disable some user app start ups. Becoming less useful as time goes on
Not clear what you might be paying for App does not seem useful without paying something to get features. Yet the 2.79 to pay for ad removal does not promise to add features. I didn't want to risk it. Moving forwards, the app as presented seems almost entirely useless. This is honestly how it looks.
