Can anybody tell me what APK this is?…
If you highlight the app, use menu button, select uninstall … It will ask you, "are you sure you want to uninstall “name of app”. Then you’ll know what it is, select yes uninstall or cancel.
you have an account and subscription? Perhaps check your emails, or do a ‘lost password’ request and they will email you. 
Sorry… That isn’t my photo, or my screen, I just want to know what it is as an alternative to Cinema
