"App idea 1: ShitAdvisor - have you ever been in a new city or town and needed to take a number 2. “ShitAdvisor” or “wherewee” is an app that like TripAdvisor or Yelp that rates free to use toilets with photos, reviews, maps and a Score out of 5 stars. It’s a novelty app but with a real use case. “The toilet in 5 guys is great you can just walk in and use it, the staff don’t really care. 5 stars”"
