Yiko: Practice the Sentence You Actually Need to Say

Why it surfaced

Its premise is unusually concrete: rehearse the sentence you failed to say in a meeting, rather than follow someone else’s course syllabus. The Android beta uses your own API key, stores sentences and recordings locally, and explicitly says it has no accounts or server.

Yiko turns your Chinese sentences into natural English or Cantonese, then lets you practise saying them aloud on your phone.
