iPhone/iPod touch only: Remember previously mentioned RunPee.com, the ingenious website that tells you when to head out for a bathroom break during a movie so you don't miss any good parts? Now the site has released its first mobile version for iPhone users.
Built on the same premise as the website, RunPee's iPhone app tells you the most opportune times to head out for a bathroom break (e.g., @ 35 mins.). Like the site, RunPee Mobile also lets you know how long each "PeeTime" lasts, and what happened while you were away.
The application also has a built-in timer (which you can start at the beginning of the movie) that will keep track of all RunPee times so you can decide whether to go then or, well, hold it until the next designated break time. It will also tell you which movies have extra scenes after the credits.
The creators are also working on more features that will be rolling out "every few weeks", including a friendly vibrate reminder to alert you a few minutes before a RunPee time.
RunPee Mobile's iPhone application is compatible with the iPhone (O.S. 2.2.1 or later) and iPod Touch, and costs 99 US cents.
