Well, I see a lot of bad reviews here, so Im gonna chime in.
Reason why I gave it such a high rating is because it has literally saved me from peeing my pants. I had to pee so bad, and I was in an industrial area where its anyones guess as to which direction led to a place with a washroom.
I was literally going to pull over and just pee on the side of the road, but I managed to hold it in.
Now, this app would have gotten 5 stars if it only wasnt so buggy. It crashes, and freezes, and when I try to add pictures it glitches out. Also, I just tried to recently add a washroom and it wouldnt let me, saying something about having to go to the website to upgrade my account or something like that. And when I go to the website on my phone, it says "too many redirects," so I cant even go to the website! I would give this app 1 star for all of this, but it HAS saved me from having to pee my pants. So, the best I can give it is 3 stars.
