It is quite difficult to use an inhaler properly, and many people who use inhalers for their asthma make mistakes. This can mean that the full dose is not reaching the lungs and that people may not be treated as well as they can be or may experience more side effects from the medicine.

This study is testing a new tool designed to help people take their inhaler effectively. The tool has two parts, a small device that fits onto the inhaler and a companion smartphone app.  Participants will be randomly allocated to either use the new tool, or to continue with their usual care,

It is being carried out by a team of researchers at The University of Manchester
