The app offers a pretty bad pronunciation where the voice talent swallows part of the words. Im a German native and I would probably speak this way with my peers but I dont want my kids to learn their first German words from this app.
Example:
The word "Brezel" is pronounced "Brezl" in this app. Wrong!
The word "Erbsen" is pronounced "Erbsn" in this app. Wrong!
I could go on and on.
Another thing that really bothers me that all the words are missing articles. In order to learn a language like German, ones got to really know them.
