Readable is a new app for graded readers and daily news. Learners can read as much as they wish for free (with ads and machine-generated audio) or through a paid subscription (no ads; human audio). Intended for fluency practice and reading for pleasure, readers do not feature quizzes or exercises, although learners can store vocabulary for future self-study.
