There are many devices that measure activity and Shine is another one. The strange thing is that it has not been released but it still seems interesting to people. It is waterproof and it is small. The device is something that would be useful to the people with FitBit and other Fuel band’s out there, the Shine is one that will get more attention combined with appropriate software.
With these devices, the characteristics of the electronics are standard but what may differentiate them might be the software and the data mining that is provided.
With almost no information provided, except the need for more devices on their website, in the early days of the company, it is hard to decide whether companies that provide devices for “quantified self” can differentiate themselves. The one thing common with them is the ability to pre-order the device!
