SuperFreezZ is an Android app that makes it possible to entirely freeze all background activities of an app.

Any contributions are welcome.

SuperFreezZ is not yet another task manager promising to delete 10GB of data per month or making your device 2x as fast. This is impossible. You should freeze only
  • apps that you do not trust (and do not want to run in background) and
  • apps that you use very few.

If you freeze apps that you use daily, the battery of your device will drain faster and these apps will take longer to load. You should take the name seriously: SuperFreezZ will super freeze your apps, and it is not that easy to defrost them.

Download


Features:
  • Optionally works without accessibility service as this slows down the device

If you have a problem or a question or an idea or whatever, just open an issue on GitLab!

If you would like to help, have a look at the issues or think about what could be improved and open an issue for it. Please tell me what you are going to do to avoid that I also implement the same thing at the same time :)

Donate
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.
Also, I will upload it to the Play Store when I earned €25 through donations (because uploading to the Play Store costs that much)



Q/A:

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

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

I built and installed the app on my phone, but I couldn't get it to work. Can you please let me know how does it work? After some guiding pages, it reaches to a page with yes and no question. after selecting each of them, it shows a circle progress above the page and does nothing.
I liked the idea about the app so I'm very excited to get it to work
Thanks

Sorry, I didn't see your post, I thought that I'd get a notification when someone posts something here...
Anyway,
it shows a circle progress above the page and does nothing.
Doesn't it say "ALL APPS" anywhere? Quite strange...
What Android version are you using?
Can you send me a log excerpt (
Code:
adb logcat
) or even traces of the running stacks?
What happens when you wait 2 minutes?

The app should run in the background and automaticly freeze pre-selected apps just like Greenify does, overwise it's not much useful to me.

Been using this app for a week and like it alot. Especially as it seems to be one of the few open source options.

Only thing I miss in this is the ability to freeze system processes or the bloatware apps coming with the phone. Many of them are possible to freeze manually, but unfortunately they dont show up in SuperFreezZ.

Then there is the problem with restarting apps. As dimqua mentioned there is a need for autofreeze.

Good point, I will add it when I implement settings: https://gitlab.com/SuperFreezZ/SuperFreezZ/issues/8

And see https://gitlab.com/SuperFreezZ/SuperFreezZ/issues/15.

Hello,

I am really interested in switching from Greenify to SuperFreezZ, but am not entirely clear as to what the differences between the 2 apps are (if any).

What difference is there between freezing an app and hibernating it (which is what Greenify does, right?)? Why would it be a problem to unfreeze an app once it has been frozen, and does this process differ from what Greenify does with apps that have been hibernated?

There is no difference between freezing and hibernating.

And neither SF (SuperFreezZ) nor Greenify have anything to do with unfreezing/de-hibernating, the Android system does this from itself when you start a frozen/hibernated app. It is a problem because you will have to wait some more seconds until the app is loaded and the process also consumes some energy. And it does not differ from using Greenify at all, except for the fact that the developer of Greenify doesn't warn you.

So - actually you will see what the main differences between Greenify and SF are when using them. There are almost no "hidden" differences.

I implemented both of these features, you will have to look for them in the settings though. This is because they are rather for advanced users (that is, those who have a look at the settings).

Can you explain if it is useful on android pie or just redondant?
It depends. SF can completely prevent apps from running in the background.

Newer Android versions (like, Pie) let the apps run in the background fewer and fewer when they are not used, to save battery. SF can make SURE that apps do not run in the background at all. From https://gitlab.com/SuperFreezZ/SuperFreezZ:
  • Get back control over what runs on your phone (this did not change)
  • Enhance battery life and reduce mobile data usage by freezing rarely used apps (hint: the system will also let them run in the background only a little, even without SF).
  • Especially useful while you are on a tour, where you need only some apps but a long battery life
If you want to be really sure, you will have to test whether using SF saves battery yourself on your particular phone with your kind of using it.

Update: Apart, apps cannot use the camera or get your current location or use the device sensors while they are frozen.

Update 2: Also see https://www.xda-developers.com/superfreezz-freeze-background-apps/

It depends. It seems not to make sense to just duplicate this functionality on the first sight, but: Is there any reason why you would prefer SF over Drowser?
First of all, thank you for this cool foss greenify alternative.

I don't think you should worry much about copying that since "am force-stop" is first result when searching "kill android app command" and the accessability thing seems like a more complicated hacky workarround. Having this as an option for rooted devices would be helpful, especially for killing apps while locking the screen as I could not get that feature to work reliably so Im left with freeze shortcut. I like this freezZer more because I find default delayed freezing the most convenient way to save some wattbytes having way more installed apps than I'd like to admit. (Seriously, why would someone need to have an app that calculates dew point? No idea but it prooved itself that one time and it's only 127kB!)

Intelligent feature could maybe be improved by logging usage and delaying freezZing more (in defined bounds) the more frequently given app is used, but this may be a hustle to implement.
