## What is PEF Aware?

PEF Aware helps you track Peak Expiratory Flow (PEF) measurements for asthma diagnosis and monitoring. Replace paper PEF diaries with an app that stores data on your device, reminds you to measure, and creates PDF reports matching standard forms.

TRACK YOUR MEASUREMENTS
Log morning and evening PEF values with separate entries before and after medication. View daily summaries, variability, and history across monitoring periods.

DESIGNED FOR CLINICAL USE
Generate PDF reports; ready to share or print for your healthcare provider.

STAYS ON YOUR DEVICE
No account required. Your health data is stored locally. Optional export/import and iCloud sync on iOS let you back up when you choose.

REMINDERS
Set morning and evening reminder times so you do not miss measurements during a monitoring period.

PEF Aware is a tracking tool. It does not replace medical advice. Always follow guidance from your healthcare professional.
