We just released a set of sample TapToTalk albums in German. These are in TapToTalk Designer in the Deutsch-Kind category, and can be used as a starting point for German language albums. You can try these albums using the TapToTalk Web App.
With TapToTalk Designer, you can create TapToTalk albums in any language. TapToTalk is currently used in over 40 countries, in over 20 languages.
Special thanks to Michaela Schaenke for her suggestions for improving our translations.
