Appropriately enough, it uses Bluetooth...

The idea isn't new though, this just seems to be aimed at a younger demographic.

However, there's something about holding a toothbrush in one hand and a smartphone in the other that... just doesn't feel right to me.

Edit: gamification of toothbrushes for the young ones has been done before too:

I suppose the difference is what they use the data from the toothbrushes for. OralB produces pretty dashboards with the information while this is a game. I suppose this is closer to your rainbow example.

Another difference would be that this is not a toothbrush in itself so it can be used with multiple manual toothbrushes.

I would agree that holding the smartphone in the other hand is a bad idea. It would be better to prop it up against something or use one of the bathroom kits showed in the video on the page.
