I hate seeing the bright phone screen in the middle of watching a film. [I have no idea if cinemas have a formal policy on that, though] That said, the app had a "low key" design so it doesn't shine bright in the theater. ( Theoretically anyway). When the movie starts you start the timer, and put the phone in your pocket. The the phone vibrates when a pee-time comes up. You don't have to take out your phone [until you're in the bathroom and want to read about what you're missing].
