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 Even when it was outdated (which I think that's the cause it got booted from the PlayStore?).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!
Luckypatchers.com is the real one.
Also you should avoid pureapk, it has malware.
I recommend sticking to apkmirror if the application is available there.

uBlock filters – Badware risks
The warnings pop up and hitting proceed shows scammy fake virus scans and such. To make it clear, it's not luckypatchers itself, but the dodgy full screen ads on load.
Lucky Patcher is Android only.
Also, you should really consider getting an adblocker because the entire web is covered with malvertisements.
Even YouTube has scam ads & malvertisements.
Thank you, and yes pureapk is a trash site.
