One of the best apps to find public restrooms is one known as Flush. The app is free, and it has over 200,000 bathrooms in its database. However, bear in mind that it works best depending on which country you’re in. SitOrSquat, Where Is Public Toilet, Got to Go, and Toilet Finder are some of the other good Mobile apps you can install and use on your iPhone or Android Phone to find public toilets near you.
