Fantastic way to help control your asthma

Using this app and the smart peak flow meter is a fantastically easy way to help control your asthma in a really easy way as the device is so portable it really does help you to keep track without a big bulky pfm in your bag taking up valuable space. I was surprised just how easy to use it was but just as a tip get the full Bluetooth pack I first started using this device when it came out when it was just plug into a headphone Jack and that is much more tricky to get your hands all in the right place. But once the Bluetooth handle came out this changed the device totally and makes it far superior. But if you can only afford the plug in that is still a very good option too you won’t be disappointed. I wasn’t. Here’s to happier lungs

Update two years on from first purchase my lungs are much happier and much more stable I place a lot of this down to the use of this app and the peak flow meter.

Two brilliant innovations

I have used the SPF over the past few months to monitor my occasional and transient asthma.
(Now with the COVID-19 situation, management of any current asthma becomes even more important).
The SPF device is a brilliant bit of kit; so simple, elegant, and really functional. It is a pleasure to use, which means daily usage becomes an easy routine.
The only niggle was that, as an iPhone-user, the SPF device can only attach to the iPhone through a short adapter cable.
However, holding the SPF device and the cable and the iPhone, and pointing the window on the device at a good light source, all whilst giving the best possible blow, was always a bit awkward.
So I was very pleased to read about the new availability of a BT-enabled “handle” for the SPF device. I ordered it and it arrived quickly, in the usual elegant packaging. The setup via the app was so simple that the printed directions for use were superfluous.
I tested the SPF alone and then with the BT handle immediately afterwards, just to compare. Now with the handle, the SPF device is so much easier to use.
In summary, those guys at Smart Respiratory Products have made another really innovative solution to improve asthma management.

Great device and brilliant customer support!

This device is just what I needed but initially I had trouble with my iPhone which kept changing to voice control! On speaking to customer support they sent me a Bluetooth device which solved the problem - apparently a lot of iPhones are not picking up the smart peakflow through the headphone jack point! Brilliant for monitoring my asthma and I was able to export the data to my email as a pdf and send to my GPs asthma nurse to be attached to my annual review records! Thanks guys for your help!
