Everything you enter stays on your device – the app never connects to a server. IN YOUR LANGUAGE Tauschbuch speaks English, German, Italian, French, Dutch and Spanish – automatically matching your system language. WHO IS IT FOR? For everyone who trades patches regularly and keeps wondering: who have I already sent to? Who do I still expect something from? And what was that address again? Tauschbuch answers all of it at a glance. Questions, found a bug or have an idea? Reach out via the contact button in the app – every bit of feedback makes Tauschbuch better.
