Good but be careful with the in app upgrade
The functionality of this app is okay and they do work. However, be careful with the in app upgrade. I upgraded the one in iPad through in app upgrade and to my surprise, it is not reflected in the one on my iPhone. I bet if I just buy the full version through iTunes, the full version will be loaded to both my iPhone and iPad.
