Comprehensive and up-to-date
I am a complete beginner, but have been amazed at how much I have learned so far. I've been delving into the Help section, which is where you find a course in both learning the writing and the language. It's based on a website available on the web, but made convenient on a mobile device. I was moved to write this when I saw that they are continuing to update with new words, even though this is not a subscription based app. I've bought a book it recommends for complete beginners, which compliments the app nicely. *Update: I am so very impressed with the updates for additional words. This is not an orphan app, begun and forgotten. Just the opposite. We benefit from current scholarship
