Toilet Finder App Finds You Nearest Toilet During Emergency Situations

The app's been made by Tran Diep Bang, a 17 year old guy who's not even graduated yet. He's been testing the app for the past few months and has released English & Vietnamese version on Android App store (download links below).
We like the idea and think it's incredibly useful. In fact, in countries like India - the app would be even more useful. We hope one of our CEans will take a lead and code this app. One addition we'd like to see on this app is the 'review system' - so that people can rank or rate the toilets.
Let's start collecting a list of features this app can have. Looking forward to your innovative responses through comments below.
