Freeze annoying apps

How to install

Get it on F-Droid


Android app to completely stop all background activities of other apps.

Enhance battery life and reduce mobile data usage by freezing rarely used apps
Get back control over what runs on your phone
Especially useful while you are on a tour where you need only some apps but a long battery life

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

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.

Instead, SuperFreezZ is honest about its disadvantages: Freezing daily used apps probably 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 about 1-3 seconds to un-freeze them. Greenify has the same disadvantages, except that the author of Greenify does not warn you about it. So: Just do not overdo it, and SuperFreezZ will be super useful.

Examples for apps that deserve to be frozen:


Optionally works without accessibility service as this slows down the device
Can freeze only apps not used for a week (can be configured)
Options to freeze system apps and even SuperFreezZ itself
Can freeze apps when the screen goes off
Completely open source and free software (GPLv3-or-later)

If you would like to help with developing, have a look at the issues, or think of something that could be improved, and open an issue for it.

Please tell me what you are going to do, to avoid implementing the same thing at the same time :-)



Developing SuperFreezZ is and was a lot of effort, which I did in my free time. Please donate to show me your support and to boost development.

Contributors and saying thanks

  • Hocuri - Hi. I am the main developer of SuperFreezZ. I started SuperFreezZ in 2018 by forking ApkExtractor. I chose ApkExtractor because it already provided a list of installed apps and SuperFreezZ was my first project, so that I was glad about not having to start from Scratch.

    Currently, I spend most of my programming time contributing to DeltaChat. It's a privacy-focused email client that looks like WhatsApp or Telegram. This means that you can chat with anyone who has an email address, with the benefits of a messenger (especially being easy-to-use). Check it out!

  • Robin Naumann made the nice intro you see when you start the app the first time.

  • Dark and oF2pks contributed some bug fixes. Also, Dark developed the "Sort by user/system" feature and oF2pks helped with the "Freeze apps using root" feature.
