Just as diabetics check their blood sugar level, through an application with the help of a monitoring device, asthmatics can also keep an eye on their lung function non-stop, with the help of a smart "peak flow meter" device.
The device measures how much air an asthmatic can force out of his/her airways, which is an objective indicator of the state of a person's asthma.
The Peak Flow smart device is brilliant (or so we like to think). Due to its size, simplicity and technology. It has no batteries but a small propeller that rotates while the sufferer blows.
The small device is fixed in the audio jack of any smartphone and works perfectly with a free application - available for iOS and Android.
