SuperFreezZ

SuperFreezZ is a useful task manager app which will completely stop all background activities of other apps that deserve to be frozen (untrusted, rarely used and annoying apps).

Features:

• Optionally works without accessibility service as this slows down the device
• Can freeze only apps not used for a week (can be configured)
• Choose a white list (freeze all by standard) or a black list (do not freeze anything by standard)
• Can freeze apps when the screen goes off
• Options to freeze system apps and even SuperFreezZ itself
• Completely open source and free software
