User reviews

Brilliant at helping me keep track.

I’ve only just been diagnosed with Asthma and have been trying to get to grips with this new routine of inhalers and peak flow and this app has really helped me.

Disappointed

This app starts off really well letting me track my peak flows however for the last month is not shown any of my peak flow readings on what my average reading is. Really disappointed with this app.

Peak Flow

A great app to monitor my asthma and to have regular scores to show the Asthma Nurse at my reviews. Thank you so much.

Pretty good

Very easy to use, create a graph for you. Only thing that would be better is if the time reading was taken was clearly displayed

Impressed
