Hallo German Coach

Hallo German Coach helps learners practice German they may actually need in Germany. Instead of staying at vocabulary memorization, it organizes real-life conversation situations such as housing, work, doctors, pharmacies, public offices, shopping, restaurants, transport, travel, and urgent help. Learners can listen, speak aloud, compare speech-recognition results, save important words and sentences, review them with spaced repetition, and optionally use their own AI API key to create custom conversation scenarios or feedback for personal situations.

Practice real-life German conversations and add custom AI scenarios.
