The app even has user ratings, so you'll know if you're going to be walking into a vomit-soaked hole in the wall with nothing more than a horse trough to piss in. You can also add places yourself, so if you've been looking for a way to invite dozens of urine-filled strangers to your home, here's your chance. It's like Yelp, Google Maps, and OKCupid rolled into one!

Wait, the nearest toilet is in Taiwan? Fuck that, we're holding it.
The "free" in the name comes from the fact that the app was originally developed for drinkers in Europe, where a terrible device known as the "pay toilet" exists. However, it's also handy for Americans, as even our Bill of Rights does not guarantee that a business will let you, a random drunken lout, whiz there just because they happen to have a toilet. Not yet, anyway.
