RunPee, that great website that tells you precisely the best time to run and pee during a movie so you don't miss anything good, has taken the next step and released an iPhone app for quick reference.

The RunPee app features a countdown that lists all of the most opportune times to dash away, and like the site, it'll tell you what happened during your pee break. We're a little bit iffy on people constantly whipping out their iPhones to check anything during a movie, but hopefully this won't lead to any extra film-watching rudeness. The app is available now (link will open iTunes) for $1. [Mashable via Lifehacker]
