This is the app called Franco Kernel Manager, one of the best kernel managers that are out there… Even when it was outdated (which I think that’s the cause it got booted from the PlayStore?).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!
Couldn’t agree more on it being a bad justification for piracy
Though if you bought it and the license check stops working later I’m not even sure I’d call patching it to work without the check piracy, it’s simply fixing something you own
Yeah you’re going to use the same tools but to me I don’t see it as piracy but simply a right to repair thing
