I love that this device is small enough, so it's not intrusive to wear. This opens it up to the many people who would benefit, but wouldn't wear something too big & bulky that it disrupts their day.

Asthma is a condition which affects many people, and for chronic sufferers, can be a big problem. So, an early-warning is something which can massively benefit their lives.

Great news for sufferers & great use of tech.
