While the next iPhone might be able to quantify your health and fitness, your current one cannot. A new iPhone case called Wello, however, plans to change all that. Wello has built-in sensors that give you a glimpse into your overall health simply by holding your phone in a certain way. The case can measure your heart rate, blood pressure, temperature and blood oxygen levels. It can even display the ECG waves from your heart or test your lung function with a small attachment that you blow into. Thinner than most mainstream iPhone cases, Wello is able to pair with your Wi-Fi scale and regular fitness trackers to help you keep an overall picture of your health. Wello’s creator says additional add-ons, which could let you do things like test your glucose level, may come in the future. Pre-orders for the $199 device are available now, and will ship to more than 30 countries this fall for use on the iPhone 4S, 5 and 5S.
