GNU Taler (Taxable Anonymous Libre Electronic Reserves) is a privacy-preserving electronic instant payment system that is fully free software. It uses electronic coins stored in wallets on customer’s device. Coins are like cash. Users can use Taler to pay in existing currencies (i.e. EUR, USD, BTC), or use it to for instance create new regional currencies. The Taler wallet is currently available as a browser-based WebExtension and as Android app, but not yet as iOS app. This project will develop a user-friendly and accessible iOS wallet app for the GNU Taler payment system. With the iOS Taler wallet app, users will be able to make payments with their iPhone — similar to how they would use proprietary payments systems like Apple Pay.
