I haves used SPF for several weeks now & find it so easy & convenient to use.
There are however a couple of enhancements that I would find useful. Because I use it primarily to measure & record my FEV1 readings twice daily but not to manage my use of meds etc., it would be really useful to be able to switch off those options in settings.
Most importantly would be the inclusion of a ‘month’ view in the graph. The jump from week to quarterly excludes from what to me (& surely most people) would be essential viewing. That would elevate it to a 6 star app :)) - David

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

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.
