Crashes and Freezes constantly – HP Reveal Review

This app continues to freeze and crash. I would love for it to get fixed and updated so this does not happen. I am trying to use it with students and it is becoming a real problem. Please fix this! When I try to go to App Support, an error message shows. How can I get help with this app? Please help ASAP!
