Key Highlights Of The Software Peak Flow Diary (Asthma)

Missing small changes in your breathing can lead to worsening conditions.

Peak Flow Diary is an app that allows you to record your daily peak flow values and visualize changes in your breathing through numbers and graphs.

By keeping a record, you can more easily understand:
- Your condition when you are feeling well
- The timing when symptoms start to worsen
- Daily changes and trends

This helps with your everyday health management.

Another feature is that it makes it easier to communicate your respiratory condition to your doctor during consultations by looking back at your recorded data.

Key Features:
- Record in seconds, easy to continue daily
Supports two input methods: slider and keyboard. You can continue recording effortlessly using the method that suits you best.

- Understand changes at a glance with graphs
With easy-to-read graphs that support zone displays, you can quickly check changes and trends in your breathing status.

- Easy to review with history and notes
You can check past records in a list and save notes along with them. This allows you to look back at your records alongside your daily physical condition and events.

- Clear communication with consultation reports
You can view your recorded data as a report, which can be used for explanations during medical appointments or for personal review.

- Prevent missing logs
Setting reminders helps you avoid forgetting to record your data.

- Peace of mind with cloud storage
Since data is saved in the cloud, your important records are protected even if you change your device or lose it.

- Simple and easy to use
Because it is something you use every day, we focus on a screen design that is intuitive and easy to keep using.

For those who want to maintain daily records without stress.

Why not start a habit of noticing changes before they get worse with Peak Flow Diary?

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.

Best of the ones I've tried so far! Easy to use, no user necessary, and automatically calculates ranges. I wish I could enter exact numbers, as it only gives you increments of 10s (so if I measure 455, I'll have to put in 450 or 460). Would also be really nice to be able to input fev, but that's asking a lot 🥰

Thank you for your feedback! If you switch the input mode to the keyboard, you will be able to enter exact numbers like 455. Please give it a try!
