Not up ... 9

Overall, I am disappointed by:
* Navigation: I imagined a navigation "slide" on the touch screen, but you must press the small button to advance
* Cardiac measurement uses the same trick as smartphones: you stick your finger in a diode and a small sensor grabs the brightness difference, hence they derive oximetry and heart rate (incidentally this is how it works medical devices for oximetry)
* The passage in "night" is not simple, I think they have forgotten some of their users also making alambiquer to go on this menu, I do not understand why we can not just drive the sensor with his telephone!
* The worst for my mother slipping out of the sensor support "wristwatch", so as to avoid the risk of losing your precious
