Asthma Tracker: Peak Flow is a focused asthma diary and monitoring tool for people who live with asthma and for clinicians tracking patients. The app helps you record symptoms, peak-flow readings, inhaler doses and environmental triggers quickly—daily check-ins take about ten seconds—so you can spot patterns and share clear reports before appointments. Asthma Tracker: Peak Flow combines medication reminders, personalized green/yellow/red peak-flow zones, air-quality and pollen alerts, guided breathing exercises, and one-tap exports so users can manage routine care, prepare for doctor visits, and reduce the guesswork around worsening symptoms.
