Freezes up phone completely

Freezing up the screen and the phone where you have to turn off the phone and turn it back on for your iPhone to work. I have an I phone 6S. Had to uninstall & reinstall to many times to count - emailed Perk and problem still remained - freezes up after commercials too. If there was a lower then 1 star to rate this app - that what I would rate it
