This app tells you when to hit the toilets during long films

Rumble / Weird Science — ‘Avengers Endgame’ opened this weekend to a record number of people to their local theater.
At three hours and two minutes, ‘Endgame’ may not so great for your bladder if you had a soda.
Lifehacker suggests that if you’re planning to go see the film, before you go, download the app Runpee.
Runpee has been around for years and works for a number of popular films.
With the app, you set when the movie starts and it will vibrate when you have time to pop out.
