This would be handy for when you are fishing offshore. It always seems that the fish come on the bite when you go to have something to eat or want to relieve yourself. All the best, Colin

An enterprising freelance software developer in the US has come up with an ingenious solution to that wee problem of when to dash to the loo when you're at the movies.

RunPee.com, created by Dan Florio (aka polyGeek) tells you the best time to go.

"Every movie has a few minutes you can miss and not be lost when you sit back down. No more guessing when to run and pee!" the site says.

RunPee.com "reviews" are posted by users.

A recent example, Star Trek: "RunPee approximately 50 minutes into the movie when ... Capt Pike leaves the bridge on his way to Nero's ship and says, 'Chekov, you have the con'."

The site also tells you how long you have before you need to be back in your seat.

When you get home, you can click on a link on the site to tell you what you missed while you were away.
