What users praise

  • • Unlimited low-stakes conversation reps at roughly $8/month beats private-tutor pricing
  • • Tutors remember prior mistakes, so later sessions feel warmer than the first
  • • Cross-session memory and adaptive study plan personalise practice over time

What frustrates them

  • • Mispronounces French 'est' and reads Japanese kanji and kana incorrectly
  • • Can't hold a dialect line — European Portuguese kept reverting to Brazilian
  • • Beginner course described as unintuitive and already too advanced for zero-level
  • • Push-to-talk listener mishears, and the app ships with no onboarding instructions
