What do you do when you need to run to the loo during a film

I am so excited about the new app I found to help me catch the important parts of the movies I go to see. Isn't it just the worst when you are at the movies and you find yourself needing to run out to the loo? RunPee tells you the best times during each film for you to run out. You input the movie you are at and press the timer button after the previews finish and the film begins. Your phone with vibrate a few minutes before each of your ideal breaks! How simple! Enjoy!
