Comments on Peak Flow Diary (Asthma) for Android

★★★★☆ Alison Mutch · May 9, 2026

I need to be able to change the zones green 347-434, yellow 218-345, red 217 and below. 52 female 5'7" 210. Current zones don't reflect me.

★★★★☆ Montaigne · Jul 12, 2026

A useful tool to help anyone with breathing issues to maintain a good record for professionals to consider. Simple interface that does what it says on the tin. VG.

★★★★☆ Keris · Jul 17, 2026

Very good app definitely recommend very helpful ful to see charts but unable to see symptoms trackers but peak flow charts help me more.

★★★★☆ Nikolina Skorupan · Apr 11, 2026

Easy PEF logging with a clear graphical overview. Major downside: no PDF export for data or charts. Additionally, the graph fails to update with new values after one month of use. Update - the graph problem is solved with new version. Still no option for export for data

★☆☆☆☆ Jenn Perry · Aug 29, 2026

14 day free trial, then $3.50-ish a month, or $25 a year feels like it. This info should be included in the app description. I may come back if I can't find a better option, but for now I won't be using this app.

★★☆☆☆ Kathy Burns · Jul 25, 2026

I like the app but came in today and find out it's not really free and my previous information has been deleted unless I pay $24.99 annually. Very disappointed because although it's basic I'm unable to afford to continue using it.
