This used to work in tilt mode, where you control by tilting your iOS device. Hasn't worked for a long time. A normal company would fix this inside of two weeks. Great little toy. Broken software. Awful company.
This product was a source of much heartbreak and many lost hours. it has so much promise but does not have any of the ease-of-use that one thinks of when one thinks about Apple. (I know it's not made by Apple.)
It feels like the manufacturer hopes to survive mostly as a platform instead of as a final-product provider.
