First, there is a lot of under the hood enhancements, including a whole new system for storing data. The application should be faster, even with a large collection of words, whatever device you're using.
As previously announced, the main improvement is the full support of the iPad. I adapted the user interface to take full advantage of this big and beautiful screen, using elements from both the original mobile version and the official iPad interface, in order to keep the experience as enjoyable as possible.
This new kind of devices is perfect for learning, and I really want Memorii to exploit this potential, so I hope it will help you as much as possible.
