Ever been in a situation where you really had to go but didn’t know where? A good friend of mine is notorious for always having this problem, and he’s earned the name “Whiz Master” as a result.

So leave it to Charmin to sponsor the app called Sit or Squat, which combines geolocation technology and a database of public bathrooms to help you find a bathroom no matter where you are. And for new parents out there – it even has a function that allows you to search specifically for bathrooms with changing tables, which I know can be super important to families on the go.

The most interesting feature of this app is that it allows users to post star ratings, photos and comments. Similar to Yelp, it also provides more info about the bathroom, including its hours, amenities (like seat covers and handicap access) and even contact information. And if you discover a bathroom or have a well-kept secret you want to share, it allows you to add to the database too!

One caveat: the app essentially lists any place (a restaurant, coffee shop, bar, museum) that has a bathroom inside it, so it’s not always going to give you an option where it would be appropriate to just walk in and use the toilet without going unnoticed. But, if you gotta go, you gotta go.
