What’s New

Version 1.7.2

This version includes several bug fixes and performance improvements including the addition of the Finnish language. Another key update relates to the PB (Personal Best) reading. Your PB value doesn’t automatically increase when you take a higher peak flow measurement, although you can modify your PB on the Profile tab by manually adding it if you know it. If you don't know your PB the app will use a medical formula to calculate it based on your age, height and gender.

Device doesn’t work on newer phones

The device will not connect to my iPhone 8 no matter what adaptor I am using. Good news is that it works on the iPhone 5 I had laying about. Bad news is there is no way to see the peak flow data on my iPhone 8 - without the device connecting it won’t move on to the dashboard, and since it doesn’t connect to the health app I can’t get the data there either. This serves me no better than using the regular peak flow meter and manually entering the data.

Developer Response ,

Hi Kate,

Sorry to hear that the device is not connecting as expected. That is frustrating. We've since released updated versions of the app which should solve this issue. Also, we'd recommend checking if you're using a genuine Apple lightning to audio jack adaptor as we've seen this issue more commonly with non-genuine adaptors. Regarding the health app, we're also working on an integration for that which should be released in the next few weeks!

Thanks again Kate for taking time to leave your review!
