Needs improvement! I would love to use this app on friends phones as a prank but the ad and the fact that you can't do anything while the app is running ruins it. I know apps can do screen overlays because I use a screen tenting app. If you could get the app ad free and not interfere with the functionality of the users phone and could also make the finger prints bigger (life size) then I would rate this app 5 stars and I would recommend it to my friends.
Fingerprint on screen The best app ever
lame do not get it its lame
Fingerprint Is the best app
Love it Si esta vuena
