Best Sudoku App

I have tried many Sudoku apps. This is by far the best. The interface is easy on the eyes. The layout and options are very intuitive. The hints also give the option of using a tutorial so you can learn as you go. One thing that I think could be better is the gradient on the hints. For example, it goes from telling you what pattern to look for directly to showing it in the next step. I would like to have a number hint so I can find it myself before it is shown to me.
