Lemnly is the calm way to learn a language: read real stories and articles, tap any word for an instant translation, and every word you look up becomes a flashcard you'll actually remember. No leagues. No hearts. No streak-guilt. Just reading β and vocabulary that sticks. HOW IT WORKS β’ Read graded short stories (A1βB2), classic books, or import any web article. β’ Tap a word for an instant translation, part of speech, and example β plus a one-tap grammar explanation. β’ Every word you collect flows into smart spaced-repetition review (FSRS) that schedules to your memory, not to a streak. β’ Watch your reading vocabulary β and your estimated CEFR level β grow. WHY LEMNLY β’ Calm and beautiful, built for your phone first. β’ The whole read β look-up β remember loop in one app. β’ Honest coaching from Bodhi β real competence over fake motivation.
