Doctor's thoughts

"This is a great alternative to written paper diaries.
You can easily download the app and get accurate measurements.
Also, those who are less tech-savvy get feedback on the accuracy of their measurements."

    At first I had trouble with the app giving measurements when I hadn’t blown. (due to certain types of lights) This has now been fixed. Easily fits into my bag, allowing me to take a reading anywhere, anytime. My GP was impressed when I went in for a review and I was able to show her how my peak flow measurements had been since the start of the year by showing her the graph. My only complaint is that the mouthpiece to the meter falls off very easily.

    This is a brilliant device

  3. Sharon Beaumont

    Brilliant device. Bought it as my last asthma attack came on so quickly it was scary. However, after using this device on a daily basis it gave me an amber warning and advised I took my blue inhaler even though I didn’t have any major symptoms at the time. you can clearly see from the app that my asthma isn’t under control properly so I can now show the readings to my GP and hopefully get sorted.

    Veri conviniant for younger astmatics

  8. Anonymous (verified owner)

    I think every asthmatic should have this. This has breathed new life into my previously sporadic asthma care. Start the app, plug in & blow, result explained & logged in the diary-done! Also, an option to make a note & view the graph. The only nit pick I have, is that the clear mouth piece could do with a slightly tighter fitting.

    Great little gadget, nice app too, but can’t figure out how to get my data out of it.

  10. Zita

    Perfect, easy to use

    I have a teenage son who has asthma – albeit only with a cold (virus) which can be quite unpredictable.
    I was looking for an app to document his peak flows and came across your product which is a fabulous innovative idea. I have a typical teenager who thinks normal graphing of peak flows is boring. Consistent peak flow monitoring has therefore lacking. Anything to do with technology and he’s interested.
    He also needs to be more involved in his asthma management. The app and smart peak flow metre have allowed him greater engagement with his chronic condition. I’m a registered nurse and love the use of modern technology and health innovation.

    5 for recording my peak flow ellegantly.
    -1 for not working on Pixel3 XL via microphone to usb-c adaptor.

    Efficient and compact

    Needs getting used to as if you are wheezy it sometimes doesn’t register

  19. Grace (verified owner)

    Great device easy to use. Needs a direct source of light above you or it gives some very peculiar readings! The device takes your highest resting not an average and you cant add any readings from a manual PFM. It definitely makes tracking my PF easier and PDF of results can be shared directly to my doctors which is fab!

  20. Susan F. (verified owner)

    An easier way to keep track. Only problems are – need to be in a well lit room at night, think it gave me too high a personal best to start with as I’ve had to reduce it to make it more realistic and I could do with a narrower mouthpiece, the doctor gave me a child’s peak flow meter as my jaw doesn’t open enough. Otherwise very happy – even happier when I get green!!

    Since most recent app update, it works well. I do get some variability with differing amount of room lighting – however, this is expected. I’m a health care professional that has tried using this device.

  22. Kevin Wilkinson

    Easy to use and seems very accurate.

  23. Jacques D.

    With Smart Peak Flow I now know how to adjust the prescribed medication and so avoid hospitalization. Before, whenever my asthma became too severe, I would have to go to the hospital for shock treatment – I no longer need to go through all that ! Many thanks go to Smart Peak Flow.
