Tauschbuch – The app for patch traders

What is Tauschbuch?

If you trade patches regularly, you know the problem: who have I already sent to? Who do I still expect something from? And what was that address again? Tauschbuch replaces paper notes, note apps and endless chat scrolling with one tidy app – built by a collector for collectors.
