Where I live (Zurich, Switzerland) it's not uncommon for shops/restaurants to open up their toilets to non-guests during busy events downtown, for a small charge. Most people don't mind paying a few bucks to use a clean toilet instead of the mobile ones provided by the city for free, which usually start smelling really bad only after a couple of hours.

I doubt I would use an app just for that though...

Z�rich also has 99 public toilets which are cleaned twice a day. Some are also staffed.
