## What is RespiLog?

Take control of your asthma with RespiLog, the complete peak flow and symptom diary that turns daily readings into actionable insights.

Log your morning and evening peak flow in seconds. Track inhaler and preventer use, symptoms, triggers, and night awakenings. RespiLog builds a clear, color-coded picture of your asthma control so you always know where you stand.

WHAT YOU CAN TRACK

* Peak flow readings with AM and PM sessions
* Reliever and preventer inhaler use
* Symptom severity: None, Mild, Moderate, or Severe
* Night symptoms and sleep disturbance
* Triggers including exercise, cold air, dust, pets, pollen, stress, smoke, and mold — plus your own custom triggers
* Air Quality Index (AQI), automatically tagged to every reading using your location

UNDERSTAND YOUR PATTERNS

* Trend charts across 7, 14, 30, 60, and 90 days
* AM–PM diurnal variability flagged when it exceeds 20%, a key asthma control indicator
* Trigger analysis showing which triggers appear most often alongside below-target readings
* AQI correlation insights to help you understand how air quality may affect your peak flow

ACT ON YOUR DATA

* Green, Yellow, and Red zone action plans, fully editable to match your personal asthma management plan
* A dashboard alert banner when your 7-day average falls into a caution or danger zone
* A built-in Asthma Control Test (ACT) for a standardized monthly check-in
* Evening reminders so you never miss your PM reading
* A quick-log shortcut from your home screen

SHARE WITH YOUR DOCTOR

* A one-tap 30-day report covering peak flow readings, symptoms, inhaler use, and trigger patterns
* Share reports directly by email, message, or any app on your phone
* Attach photos to readings to document symptoms or capture peak flow meter displays

KNOW YOUR PERSONAL BEST
