SuperFreezZ

Entirely freeze all background activities of apps.
Android app (beta) making it possible to entirely freeze all background activities of any app.

Greenify can also do this, but it is not Open Source.

All contributions are welcome.

SuperFreezZ is not yet another task manager promising to delete 10 GB of data per month or making your device 2x as fast. This is impossible.

Examples for apps that deserve to be frozen:
- Untrusted apps (that you do not want to run in the background)
- Apps used very few
- Annoying apps


Freezing daily used apps drains your battery a little faster. Also, these apps will take longer to start when you use them the next time.

SuperFreezZ will super freeze your apps, it takes some seconds to defrost them.

Greenify has the same disadvantages, except that the author of Greenify does not warn you about it.


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

Q/A:

Q: What is the difference between hibernating and freezing?
A: There is none at all. If you hibernate an app with Greenify it will even be shown as frozen in SuperFreezZ and the other way round.

Q: But the correct spelling would be "SuperFreeze"!
A: I know.

Q: Do you have any intentions to sell freezers?
A: No.
