SketchWiz : The best iPhone apps for Japan - This is a great app and it has alot of potential. I am taking off one star because the app doesn't make full use of the iPhone 4's HD camera. I'd like the option for the output to be in a higher resolution so that the photos were printable. As it is the resolution of these photos is about 360x480 which is only good for maybe a 3x5 print out. Fix this and I'll amend my review and add the 5th star.
The user interface needs a lot of work. Should remove notepad background and make it optional, because don't want the notepad lines in every shot.
Gallery area to review photos looks cheesy.
Would recommend Toon Camera instead, which has a color pencil option.
SketchWiz: turns your camera into a sketcher. Changes the way you see your world and can be used to create some awesome artwork.
