Completely agree. I like the CTC app, but I've found that the Brainium app does a really really good job of context sensitive hints. It's waaaay better for learning techniques.
I bought Enjoy Sudoku a while back and still enjoy it, but I think Branium has since become the better option.

Sudoku by Brainium.
The auto notes system is very good. And there are hints for when you get stuck.
I think I found it! The free version is called Sudoku with a green icon, and there is also Sudoku+, which costs €4.89.

I got this Android app. I get it now. Ima keep playing the super easy for a bit, but I think I can get lost in this.
