I admit I felt some dismay at the lack of notice as this is my first object connected and I feared a facility with complex settings; gold all went well; the application is loaded quickly and the connection and synchronization with my I PHONE 4 went very smoothly. given the difficulties encountered by other testers, I guess the designers have considered the comments and made rapid progress in their product. this idea is validated by the fact that in a few days, there have been several software updates. the interface is very well done, everything is simple and readable so I'm happy with the product. beyond the information collected, I find a secondary benefit to wearing the bracelet: his presence reminds me of the need to move; I think most people saccordent on that move is good for health but in daily life, we do not always take the time; when I taped to my computer, I did not measure if I sat 1h or 2 h or more ...; gold, I find that these days, seeing the bracelet, I thought "moves" and I got up! So it pleases me well and I put myself dreaming of future objects that will tell me how long I sat, which will send me a signal or vibration when my vertebrae are bunched etc ... Certainly, this is a bit like Pavlov but if the "Pavlovian" vibration can avoid me a backache, why not ??
