Games, Daily Review and progress run on your phone after voice and word packs are downloaded. Downloading packs needs an internet connection.

Flashcards, Listen & Choose, Listen & Type, Fill in the Blank, and Pronunciation.
What is Daily Review?
A short session (about 5–10 minutes) that picks words you are about to forget, so you keep what you have learned.
Do I need an account?
