It makes wallpapers for your iOS device! Pretty ones! Using, like, geometry and math.
Pick a shape from an ever-expanding list and let the power of computers and technomagic draw pretty, randomized wallpapers rendered specifically for your devices resolution. Its more complicated than it sounds, honestly. Just twiddle some sliders and tap some buttons until you find something pretty, and then hit save!
The IAP is gone, replaced with a tip jar! If you like using the app, or make something cool, why not share it with a friend?
