Your personal speaking coach. Talk a little every day, and the cat keeps track.
A few things so your tutors know who they are talking to.
Cards you saved come back on a spaced schedule. Tap a card to flip it and hear it; then grade it: Again if you missed it, Good if you knew it, Easy if it was effortless. Use "Listen and answer" to train your ear.
Everything you have learned, by exam level. Practice a level to review all of it, not only what is due.
Build a deck for your level. Items are skipped if you already have them.
Type a word in the language you are learning or in your own. Suggestions come from the exam lists; the full entry shows meanings, example sentences with readings, how the word conjugates, and related words. Tap any speaker to hear it, and "+ add to my deck" to keep it.
Your reviews per day, your streak, and how much of each level you know. The mock test gives you 20 exam-style questions for a level: vocabulary, listening and grammar, with a readiness verdict at the end.
