How do i get the gamepress IV checker app

Hi guys !
These last months i've been checking posts on gamepress daily and i have consistently seen people talking about or posting screenshots with what seems to be a pogo appraisal app, which some refered to as the gamepress app. Now i really am not fond of tier apps (im basically just afraid of getting some sort of ban after spending so much time playing) but it seems like a lot of u guys have it and use it, and i've yet to see anything bad said about it so...
Y'all got any link to it ? ^^ I'm unable to find it on the playstore and the "Gamepress app" doesnt seem to do quite what i've been seeing on screenshots.
