The beauty of this app is in its name. Sure, there are a few apps that will help you locate the nearest restroom. But if you’ve traveled through certain countries, you know that a Western toilet is still only really common in the West.

SitOrSquat also provides information on changing tables, handicapped facilities, and a little bit of humorous bathroom reading.
Everyone is encouraged to enter any new public restrooms they stumble across to the system; it’s all about helping each other out.
