Digital Peak Flow Meter,Home Medical with Tracking Software (Manually Recording)-Accurate&Reliable Spirometer for Asthma COPD Adult Kids

i have bought this device for my son he has asthma,It is showing always wrong results and i have tried so many times to connect to my phone but cannot find my phone.... i dont know i think its a waste of money and time i will try to return this device

Seems to work well, great value.

The product is easy to use and instructions are easily understood.

My doctor recommended I get a peak flow monitor due to my asthma issues. This monitor works great for the price. It beeps kind of loudly when you turn it on and it beeps when it automatically turns off. Unfortunately you can’t turn it off with the power button (it only turns the device on) but since it shuts off automatically after not using, there’s no issues with battery life. You can set up the device phone app to feed into your Apple health data which is great.

Daughter recently diagnosed with asthma. This is an accurate and easy to use. App is nice too.

works as expected. setup was a breeze but the app is pretty basic don't expect much out of it. Make sure what ever you buy is not just wifi but also automatically transfers the data. there are many others that have a low price but are manual and the descriptions are deceiving
