New Smartphone Case Measures Vital Signs.

Azoi, an American technology company, has just announced a smartphone case that measures blood pressure, heart rate, temperature, and blood oxygen levels. This new health tracker is called Wello and works by using several sensors located in the case that attaches to your smartphone. Wello can also connect to other health and fitness devices, including pedometers and sleep monitors. Hamish Patel, CEO and founder of Azoi, says that Wello can help individuals monitor their vital signs, possibly allowing earlier detection of heart disease and other health problems.
