Always the Truth

Good app, also great service. I downloaded this when switching phones, because app I had, couldn't get their app to work. Had some trouble importing into this, but wrote to dev. He wrote back quickly, suggested how to fix it and followed up. I wish everyone would do that! My only suggestions would be to have some fields you could populate, or simply add fields for say: medications, symptoms instead of having just a blank field for notes. Overall, a good app, and good graphs which really help.

Very good. A big improvement on the app I was using previously. I like the fact that the readings show up against 'low', 'normal', 'high' bands and being able to view them in graph format. Being able to add comments is helpful. This gives meaning to the numbers, and helps you remember things you would otherwise forget. Thanks for developing this app.

This app has been really helpful as a log to keep an eye on my peak flow- especially with my bought of covid/covid exacerbated asthma. Only improvement would be if I could fully edit my zones- I know my top and bottom end but there's only possibility to add my top end which doesn't quite modify the colour bands (which are super useful!) enough to be inline for me!

Hi, I am glad you are finding the app helpful. The app currently uses a standard calculation against your personal best value to set the coloured zones, but this does not fit everyone so I do plan to add fully customisable zones in a future update. Thank you for the feedback.
