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 Even when it was outdated (which I think that's the cause it got booted from the PlayStore?).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!
Yeah, exactly. It's the same reason I have little hesitance pirating a game I already have when the platform I have it on doesn't support mods (looking at you, Xbox game pass)
In this regard it's about the ability to pirate, which always comes down to the classic "it's a service issue."
The need for pirating this software wouldn't exist if the license check wasn't broken, but since it is, it's now the only way to access it regardless of your ownership or not.
Back in the day I would often "pirate" games I owned on a CD because ot was faster than finding said CD.
Or when I lived in a place with shit internet and I had games that needed an online handshake to play, I basically pirated every game that needed that check because I wouldn't be able to play otherwise
And they usually ran better too, funny that
