A prototype iPhone case tested by Engadget aims to provide a comprehensive array of vital signs, encompassing heart-rate, blood pressure, temperature, oxygen saturation & lung function.

Readings are done with your hands in a comfortable position, and the health tracker was able to return our vital signs as well as a fancy ECG graph of our heart in just a few seconds. Out of the box, you’ll be able to pair it with your Wi-Fi scale and fitness tracker, so you can keep an overall picture of your health in the same place … 

As you might guess, this kind of tech doesn’t come cheap, with the $199 price of the Wello case possibly having its own effect on your blood pressure. You can, though, reduce the cost by referring others: each person you refer who orders their own case will reduce the price you pay by $10. So if you have twenty well-off friends with health anxieties …

You’ll also need to be patient if you want to get your hands on one: the case doesn’t yet have FDA approval, and is not expected to go on sale until the fall. You can, however, pre-order it now, with models available for the iPhone 4S, 5 and 5s. Though with Apple’s iWatch expected to major on health and fitness functionality, you may well want to wait to see what that has to offer before placing your order.
