Everyone's health needs are different, and Keas brings personalized care to a whole new level. Founded by the former head of Google Health, Keas aims to provide tailored health programs for individual users by combining personal medical data with general health advice. Companies like Quest Diagnostics have teamed up with Keas to input personal data, like blood-test results, to the site. You can sign up for various plans, including ones focused on cholesterol, diabetes and blood pressure, that give you tips and reminders, and Keas will give you personal status reports with individual goals. Plus, the site lets you get social with a Facebook-like "community feed" for users to comment on their progress.
