Also built here: Shit Go Where
I built Shit Go Where on my own, on free tiers. It finds the nearest clean toilet, and I need to go walks you to the closest good one. On Telegram, send @ShitGoWhereBot (opens in a new tab) your location for the three nearest.
Check-ins keep the map honest, and every toilet carries a trust tier, so open data never passes for a toilet somebody visited. How tiers work
Right now the map holds 1,052 toilets across 50 planning areas, 160 of them surveyed in person, and answers for 183 MRT and LRT stations.
