### 5/5 — Reliable & Easy

*2024-12-11*

With all the costs I have due to my tracheostenosis, paying for an app just was more than I could mentally handle. I am so grateful to the ease and reliability of this simple app. And that I can export the data!

### 4/5 — Easy, simple, just the right number of features

*2024-03-21*

My one criticism is the intrusive ads. I would happily pay a bit to get rid of them, but that doesn’t seem to be an option.

### 4/5 — Peak flow

*2024-01-23, version 1.1.2*

I like the app and find it fairly easy to use but think that there should be a way of going back to alter certain parts or add notes if needed. If you forget something or need to add a note you have to delete and re enter all that day’s details.

### 5/5 — Great simple to use app

*2023-12-05, version 1.1.2*

This app does exactly what I need. I can record peak flow, use the drop downs for symptom levels and note anything else e.g reliever inhaler use. The ability to easily export the data to an email is great. This is such a useful app and I too would be happy to pay a nominal amount to get rid of the adverts.

### 5/5 — Simple, great.

*2023-10-14, version 1.1.2*

Tbh, everyone is a UX expert, but if you boil it down, this app does exactly what it needs to.  If I wanted to be picky, I’d say to enhance it, you could additional fields that are tracked in the Asthma UK peak flow pdf that docs ask to print out and log using. That and a way to get rid of ads. I’d pay a few quid to remove them tbh. Thanks dev!

### 4/5 — Simple yet effective

*2023-09-23, version 1.1.2*

Very simple to use, would be nice if it would integrate with apple health though!!

### 1/5 — Awful UX

*2023-09-08*

I spent 20 minutes trying to figure out how to enter data and finally just gave up and printed out the tracking chart from the Asthma Initiative Michigan.

### 5/5 — Easy to input data, readable reports

*2023-01-05, version 1.1.2*

Simple and straightforward. Useful information output.

### 4/5 — Straightforward app

*2023-01-05, version 1.1.2*

This does what it says. The notes field allows me to record oximetry as well which I have found useful.

### 4/5 — Great app

*2022-12-17, version 1.1.2*

I like the idea of everything in one place, not searching for pens and trying to remember readings.  However I agree with Eleanor about opening on the place and a reminder alarm would be great 👍
