This is the app called Franco Kernel Manager, one of the best kernel managers that are out there… Even when it was outdated (which I think that’s the cause it got booted from the PlayStore?).
I used it to check the process of my phone and monitor the active and idle drain mostly, I paid for it a long time ago, but now it just fails to check the licence and it doesn’t let me use it fully… I think there must be a cracked APK over there…
EDIT:
Fortunately the app is back in the store and hopefully that update version comes soon enough!
and big tech mass surveillance isn’t a problem?
… You’re suggesting pirating a small dev’s app…to protest surveillance by the app store owner?
That’s not how it works. If you don’t like the policies of the store, then ask the dev to put it on another store. If they refuse, don’t use their product because they suck.
Choosing to limit your product to a shitty store is a developer choice. That gives you the right to not use their product, not the right to steal it. Otherwise, pay for it and then install a cracked version to remove the surveillance or whatever
