Pixelmator combines photo editing and painting tools. It is most useful for enhancing or touching up  photography on the iPad, with rudimentary painting and basic text. It has:

  • a range of brushes including double-texture brushes, watercolours, and pixel brush (Sketchclub pixel brush has more interesting settings), but only basic size and transparency settings.
  • graphic design features include using blending layers and shapes to which features like shadows, outlines, gradient fills and fixed reflection can be added
  • text in a limited set of fonts
  • photo effects,  including kaleidoscope.

One of my favourite uses is to make beautiful kaleidoscope patterns from paintings and/or photographs.
