Wello Health Tracker

If you care a lot about your fitness and general well-being, you know how tough it can be to find reliable metrics to help you keep track of exactly how you're doing -- most devices are prohibitively expensive or just not available outside a doctor's office. But with the Wello Health Tracker, you can get reliable information about your body any time you have your phone handy. Wello is a phone cover with built in sensors, combined with an iOS app, as well as a wrist-worn activity monitor and a lung tester attachment. Together, they let you take your temperature, monitor your blood pressure, heart-rate, blood oxygen, lung function, and more (and you can easily track all that data on your iPhone so you know how you're doing).
