MIR Smart One® Smartphone Spirometer


Do you have a respiratory condition and would benefit from a self-monitoring tool to use from your own home?

Do you think that keeping track of your condition would benefit you and your healthcare advisor?

The Smart One® is a low-cost, home spirometer offering a basic level of respiratory screening that utilises bluetooth technology to connect directly to a smartphone.

It is designed to be used as a self-monitoring tool for those with a respiratory condition or as a wellness product for the health conscious.

Using the free iPhone Smart One® app, you can record Peak Flow and FEV1 measurements in the comfort of your own home with the ability to send results electronically to your healthcare advisor. This is professional-grade equipment for a fraction of the normal cost and has won awards for its innovative design.

You can input your age, origin, weight, height and sex in the settings menu which allows the app to calculate a target value and set pre-determined ranges for the traffic light health indicator. When you perform a peak flow test, the target value is displayed as an incentive.

Please note that this product is only compatible with an iPhone smartphone.
