When it comes down to it, most people would rather wait to use a private toilet over taking a chance on a public facility, but the 'Poop Pal' app helps raise the level of confidence that people have about toilets nearby. The app uses crowdsourced data to keep an updated log of cleanliness in public bathrooms around users' cities.
For people on home turf, public toilets aren't all that necessary. However, travelers are virtually guaranteed to have to use public toilets, which leaves them vulnerable to unfortunately unhygienic situations. With Poop Pal, it's easy to find the cleanest public toilets in any given area, making trips to the bathroom a little less harrowing of an experience.
