What users praise

  • • Voice-first practice removes the anxiety of finding a real conversation partner
  • • Named tutors (Tama, Raven, Skye, Noah) with mild differentiation help personalise the sessions
  • • Real-time corrections land inside the conversation without stopping the flow
  • • Cross-session context memory means later dialogues start warmer than the first

What frustrates them

  • • Level placement fails beginners — lowest level too simple, next level too advanced
  • • Tutor quality is inconsistent: one user's Dutch was misidentified as Frisian
  • • AI sometimes substitutes what it expected you said instead of registering your actual speech
  • • European Portuguese users can't get the app to stop using Brazilian Portuguese
