OhSht is built to answer one question fast: where's the nearest decent restroom. Here's the whole flow.
There's no welcome form, no password, no username to invent. OhSht opens straight to the map. If you allow location access, it centers on you; if not, it falls back to a default area and you search manually.
Pins are color-coded by rating — red to green — so you can tell what's worth the walk without opening a single listing. Filter by "Open now" or "Accessible" when it matters.
Tap a pin for hours, distance, accessibility, and reviews scored on cleanliness, privacy, and supplies — the specifics a general map app never shows.
One tap hands off to your phone's own navigation. Afterward, you can leave an anonymous review — rating, quick tags, and an optional comment — to help the next person.
