Features
Read full description

EchoLing is made for people who already save useful English from real life. See a word, phrase, or sentence in a conversation, book, video, class, meeting, or anywhere else? Save it before the moment passes. EchoLing keeps everything you collect in one place, along with the context that made it worth saving. Then it does a little more with what you’ve already chosen to keep. AI-generated questions help you revisit saved expressions without having to make study cards yourself. Home Screen widgets quietly bring old expressions back into view, including things you saved weeks or months ago. And when you need something again, search your collection and find it. No streaks. No daily goals. No pressure to finish a deck. Just the English you chose to keepβ€”building into a collection that stays useful over time.
