Glossika

Glossika trains fluency through sentence-based repetition. Rather than isolated word lists, it drills you on thousands of authentic language pairs, helping your ear catch native rhythm and intonation. The audio-first approach works particularly well for learners wanting to speak naturally.

It covers more than 60 languages, from widely studied ones to less common ones. Free versions let you try the method; premium open up the full audio library and spaced repetition tracking.
