What users praise
- • Gets shy learners speaking out loud without the pressure of a human partner
- • 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
