SwimZH answers one question: where can I go swimming in Zürich — right now, or on a day you pick?
Every public pool in the city in one list, sorted by how far away it is: the indoor Hallenbäder, the outdoor Freibäder, and the lake Seebäder.
WORKS WITH NO SIGNAL
The whole timetable ships inside the app. Opening hours, prices, lane plans and pool sizes are answered instantly and offline — in a changing room, in a tram tunnel, on a plan-the-week evening. The app refreshes its data quietly in the background when it can.
ANY DAY, NOT JUST TODAY
Swipe the day strip forward. School terms and public holidays are already built in, so a Wednesday in the autumn break shows the hours that genuinely apply that day, not the usual ones.
FILTERS THAT MATCH REAL SESSIONS
Women-only hours, men-only hours and age limits are part of a pool's schedule, not a footnote under it. Say who is swimming and the list narrows to sessions you can actually attend.
LANES, NOT GUESSES
Where the city publishes a Belegungsplan, you can see which lanes a club has reserved and which are left for the public.
HONEST ABOUT WHAT IT DOESN'T KNOW
A pool with no published timetable is shown as "schedule unknown" — never as "closed". A water temperature that could not be read says so, rather than showing you this morning's number from three weeks ago.
LIVE WATER TEMPERATURE
Open a pool and, where the city publishes one, you get the current reading together with the time it was taken.
FIVE LANGUAGES
English, German, French, Italian and Polish — with Swiss date and number formats, not approximations of them.
PRIVATE BY DESIGN
No account. No analytics. No advertising. No tracking. Your location is used to measure distance and to place you on the map, and it never leaves your phone.
Pool data comes from the City of Zürich's published pool pages and its open geodata. SwimZH is an independent app and is not affiliated with or endorsed by the City of Zürich.
