I use this app fairly regularly to locate public toilets (I walk 15-20 km daily in random directions after getting down a random bus stop in my city) and have contributed some locations as well.

I use the app "flush" for this, and it works pretty well.

Does it source data from OSM? The app store page doesn't make clear what the data source is.
