Wello: Meet the smartphone case that measures your heart rate straight from your iPhone

Another product has emerged in the rapidly expanding digital health and fitness arena, in the form of Azoi’s Wello.

Wello will be available as a case for the iPhone, and there will also be a version compatible with Android smartphones (providing your handset is running KitKat).

The idea is you hold the case, with your fingers on four sensors on its body, and the device then takes a load of readings – your heart rate, blood pressure, blood oxygen, temperature (to see if you’re coming down with a fever), lung functions, even ECG. Azoi claims that these measurements are highly accurate.

The readings take just a few seconds, and the data is then passed to the Wello iOS or Android app via Bluetooth LE, so you can peruse the results and decide how long you have left to live. Or perhaps some slightly less morbid aspect of your personal health.

The app will also sync with other health and fitness gadgets you might already own and use, such as Fitbit wristbands.

It certainly seems like a pretty comprehensive health monitoring solution, measuring just about everything, with a spirometer attachment included for free currently. The latter is how Wello determines your lung capacity and airflow, so you can decide how many more cigarettes you can get away with smoking before your blow-football skills go down the toilet.

Hamish Patel, founder and CEO of Azoi, commented: "We are proud to introduce Wello – a not so small engineering feat in microelectronics, nanosensors, imaging, data analytics and design, that we hope will make a big difference in helping the world become a healthier place. We have effectively put health monitoring equipment, typically in large form factors, into a highly convenient and accessible mobile phone case."

He added: “We believe that through improved self-awareness of key vitals, technology could very easily reduce the incidence and impact of a wide range of illnesses and diseases.”

The Wello case is now available to pre-order for the iPhone 5 or iPhone 5S, and the iPhone 4S, priced at £120. Note that the spirometer attachment is only being bundled free as an offer for a limited time for those who pre-order.
