There's nothing worse than being out and about in the city, when a sudden and desperate urge to pee strikes. It's hard to remain calm, and the more you panic about where the nearest restroom is, the more you have to go.
This is a particular issue when you're traveling. You're smack dab in the thick of things and the place is heaving with people all vying to get between you and taking a leak. If you can't think where the nearest McDonald's is, or you just don't want to slum it, then Airpnp is the luxury loo locator of your dreams.
Unsurprisingly similar in concept to Airbnb, all you'll need to do is enter your location on Airpnp to instantly see a plethora of private and public potties in your area. Some are free (like those in a local cafe or store, for example), while some are in private homes that charge a fee.
