The app is called (are you ready for this?) RunPee. It was developed because, as their web site states, movie theaters don't have pause buttons. From their web site:
The RunPee app is primarily here to help you enjoy your movie going experience by telling you the best times to Run and Pee without missing anything important. The RunPee family – Dan, Mom and Sis – see each wide release movie that comes out on opening day. We watch for 3-5 minute spans in the movie where nothing really exciting, or funny, or important happens. (Obviously this can be next to impossible for really good movies but we do our best. )
We start looking for peetimes about 30 minutes into the movie and we stop when there’s only 20-30 minutes left in the movie. For short movies of about 90 minutes there may only be one peetime. But for movies over 2 hours there may be 2-3 peetimes.
Each peetime has a synopses of what happens. So if you do need to run and pee then you’ll be able to come back to the theater knowing exactly what happened while you were taking care of business.How cool is that?!!? We all know there are spots of boredom in most movies and this app will suggest when those are coming so you can...run and pee! The app sends a vibration to your smart phone to alert you while not bothering your neighbors.
Head to their web page to, if nothing else, watch what happens to the heading on the page; pretty cute. You'll find it at RunPee.com.
