The patterns are okay but with very few options. You can’t move them by touch, as in most kaleidoscope apps, only by tapping the rotate button. Even at that you have to pay a dollar for more than two rotations. I don’t see the point of the brightness settings. The darker ones add a little dimension but shroud the image in so much shadow, they’re essentially worthless. Other Kaleidoscope apps can do much more than this.
The app also crashes on save every time.
