Seeing zero referenced arrays in the detailed data output warms my heart. Looks like no one likes the middle stall. At current employer, no one uses the first stall because the flush mechanism is partially broken and no one is motivated enough to figure out how to get it fixed. A maint dude could find this data useful to find problems requiring repair.
I will admit that looking at the headline I initially thought this was a geolocation app for urban bathrooms. To discourage the homeless most local retail establishments either supposedly don't have a bathroom or you need to explain to the front desk why you need a key and they need to think your appearance is adequate, or you need to buy something to be allowed entrance into the area at the back of which are the restrooms. This could be useful. Where I live and shop is 20 miles away in a much nicer area, but where I work, if you're out for a walk at lunch time, and you have to go, you pretty much have to use an alley just like the homeless, so an app like this to find the nearest free toilet (free as in don't need reservations and seating at the restaurant, or rented office space, etc) would be occasionally convenient.
