Reviewers mostly see ELSA as a useful pronunciation practice app that works best with regular use: they praise its instant feedback, short lessons, fun exercises, and the confidence gains that come from daily practice, with several saying it suits intermediate or advanced learners more than beginners. The main complaints are about usability rather than the core idea, especially a frustrating onboarding flow, a dated or confusing interface, and occasional speech-recognition or microphone bugs. A few users also want deeper, more realistic analysis and less inflated scoring.
