Cat Condo

Cat Condo sits on the Boys shelf of this catalogue, and opening it is the whole setup process. It is built for touch, so a phone or a tablet is the natural place for it. Its tags here are 3d, android, animal, boy, brain.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. It costs nothing and asks for nothing: no registration, no download, no launcher.
