Asthma affects more than your lungs. It affects your sleep, focus, energy, and daily routines. You may deal with wheezing, coughing, chest tightness, or shortness of breath with no clear warning. Some days are fine. Other days feel like you are trying to breathe through a straw. This app is built to help you take control. This asthma tracker helps you monitor symptoms, medication use, triggers, and peak flow readings in one easy-to-use system. Whether you have mild asthma or are managing frequent flare-ups, this app gives you the clarity and consistency needed to manage your condition with more confidence. SYMPTOM TRACKING Log daily symptoms like chest tightness, shortness of breath, coughing, wheezing, and fatigue. Track morning and evening separately if needed. Record symptom severity, duration, and frequency so you can see how your condition changes over time. INHALER AND MEDICATION REMINDERS Set reminders for controller medications, rescue inhalers, steroids, or other asthma treatments. Stay consistent with timing and dosage. Log each use and mark if taken early, on time, or missed. Refill reminders help prevent running out at the wrong moment. PEAK FLOW AND LUNG MONITORING Track your peak expiratory flow rate (PEFR) over time using a manual input or connected device. Record daily readings, track variability, and flag low zones. Over time, spot when your lung function is declining and respond before a full flare-up begins. IDENTIFY TRIGGERS Log known or suspected triggers like dust, pollen, smoke, mold, exercise, stress, cold air, or illness. Track environmental data or weather patterns that may affect your breathing. Use custom notes to describe where symptoms occurred and what may have caused them. SEE WHAT’S WORKING Compare medication use and peak flow with symptom trends. Use visual charts to understand how well your current plan is working. Share this data with your doctor, nurse, or care team to make more informed decisions together. APPLE HEALTH INTEGRATION Sync sleep, step count, heart rate, and other data from Apple Health to understand how asthma is affecting your overall wellbeing. Review how flare-ups relate to sleep loss or stress to help reduce future risk. PREP FOR YOUR NEXT APPOINTMENT Export logs as PDF or CSV to bring to appointments. Give your provider a detailed, time-stamped history of symptoms, inhaler use, and peak flow readings. No more guessing or relying on memory.
