The app for all non-Android devices
Since Apple censors gay saunas, you can unfortunately not get and install our app as an iPhone user.
However, a WEB version with few restrictions is available. Available at metropol-sauna.appyourself.net
The WEB version works (including the stamp card) on all mobile operating systems.
On the PC: Simply scan the QR code with your phone and save the page you have opened as a bookmark. By mobile: touch the QR code.
