Tauschbuch – Patch Trading Log

PatchAppStudio

About this app

Tauschbuch is your companion for patch trading. Keep track of all your trading partners and open trades – no more paper notes, note apps or endless scrolling through chats. Built by a collector for collectors.

FEATURES

• Manage trading partners with address, country and 12 categories – with search, filters and sorting
• Open trades split into "sent" and "expected", with colour markers and reminders
• Shipment tracking: tap the number to open the tracking page (DHL, Post, Hermes), or share number and link
• Exchange contacts via QR code – fully offline, perfect for collector meet-ups
• Import contact lists from Excel, CSV and TXT, with duplicate warning
• Patch gallery with all trade photos and statistics on your trades
• Label printing plus PDF export of contact list and trade history
• Backup & restore as a JSON file, automatic daily backup
• App lock via fingerprint, home-screen widget and 10 colour themes

YOUR DATA BELONGS TO YOU

Tauschbuch works 100% offline: no sign-up, no ads, no tracking. 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.
