Samsung has launched S Health, an app for the recently-launched Galaxy S III that allows users to watch their weight, blood pressure, and blood sugar levels from their phone. First announced at the Galaxy S III's unveiling back in May, the app syncs with blood pressure monitors and blood glucose meters from Lifescan, Omron, and A&D over Bluetooth or USB depending on the device.

S Health stores readings from these devices so the user can view them over time and share them with contacts or social networks. The idea is to provide a framework for users to set goals and track their progress. S Health is launching in the US, South Korea, and five European countries, and can be downloaded either from the Samsung Apps store or More Services link on the Galaxy S III.
