Digital Peak Flow Meter Spirometer Asthma COPD for Adult Kids Portable PEF Forced Expiratory Volume FEV1 Lung Tester Home Medical

I originally got the more expensive newer version but returned it when could not find the app on the Apple App store. Found out later it is shown as PEF app when you do the search they suggest and is below the one for a PDF app which is strange. But ordered this instead and prefer it. Why? Because it can be tricky to get the correct readings on these devices and you can simply enter the average reading you get in the app. But if bluetooth it would add in ones that are not accurate. This way you control the input and it is not that hard to do. So the PEF app works well for this model, better in my view. I am getting different readings from the Omron device but both are bit tricky to get correct readings. Still I find both useful. I am doing this not for usual reasons. I am doing the Breather Fit exercises which show my PEV to be those expected for half my age. I wanted to see what improvement is shown and find these devices useful for that purpose. I do find the chart function very helpful on the PEF app and can e mail that to share with doctors etc. Can also set the expected values either from doctor or per the estimate from several app choices. Can recommend both this and the Omron devices for those wanting to measure their peak flow.

Easy to use.

It is very functional but it's worth the money. Took off one star because I wish the results just went straight to the phone. The thought of manually putting it in every single time is not that great.

Excellent product. My pulmonologist recommended it, and after tracking my results, he was able to determine my next steps with more confidence.

This may seem like a good deal and has what you want or want it to do but the problem with it is it will not connect to the app and also downside is it not returnable so your out your money as well.

I have both asthma and COPD.... I have been using a VERY old style peak flow meter but it was rather bulky . This product was smaller and very easy to use...... WINNER !

It works well, but only sometimes. I often get an error result and then after about three months, it stopped working completely. Not super useful when you’re having an asthma flare up and rely on it.

Lightweight. Good size. Easy to read numbers. Accuracy good. Easy to store.Goes off automatically after a certain length of time.
