The Next Big Thing

From my own experience, when out of the house, work, school etc,  it is very difficult to find a restroom which will accommodate someone who is not a paying costumer or just isn't open to public. The application would alert people of the nearest open restroom facilities, depending on their location, along with the amenities it offers such as handicapped accessible, number of stalls, unisex restrooms, to name a few. For instance Starbucks is open for all to use, the user will be notified of said location, so that they  can do their business in peace. Similar to the way Yelp works, the reviewer can offer comments and offer a score of the facility based of cleanliness, accessibility, among other attributes.
