Digital Peak Flow Meter Spirometer with Bluetooth for Kids and Adults Asthma COPD Home Monitor PEF FEV1

Easy to set up and use.Only down side is you can't upload the data to more than 1 phone or tablet.

Works well

After my Asthma started to get worse I purchased 2 of these. One to do an overnight chart and one for daytime. After 1 month the meter used during the day started to loose segments of the display. I had planned to give my doctor two charts one for during the day and one for night. This would not work after the internet updated the software app on my tablet which was used for daytime. The chart used for night time on my phone still worked fine. The software app update turned Bluetooth off and it is now impossible to get the tablet to take the readings and sync. The app no longer finds the device but Bluetooth works fine on other devices such as ear pods etc. The other problem is the chart. This can only be exported as a picture which takes a lot of editing to look like a proper chart. I could not recommend this as a serious piece of medical kit and readings vary on the two machines. This questions the accuracy. I have now gone back to an Excel spreadsheet and a Wright spirometer.

Had issues getting to the readings screen which is needed to add the device. Kept defaulting to the next screen but eventually opened after closing and restarting the app twice.Device itself works fine and is easy to use.

Unable to use, because APP no longer available (Apple).
