Agreed, there seem to be good decks for Anki that follow different books or courses (Skritter does this too).

With regards to Whizz Learning, we definitely looked at Anki, Skritter, SuperMemo, etc. to see how they help people remember things. I felt like the the management of their own deck (or copying a bad one) can turn someone off from the beginning. We tried to make it simpler in how we grow the deck.

The system itself does try to break characters down into simpler components or symbols. It came from a neurolinguist that created the system to help stroke victims to relearn Chinese. There is some interesting science behind it that we are going to post about soon.

We just submitted to the Apple store for our first version. I would love to get your thoughts on it when we are approved.

Any other thoughts you have on Anki or other learning products are very interesting to us.
