COPD Tracker puts every breath on the record - the shortness on the stairs, the 3 a.m. wheeze, the exacerbation that shows up with a change in sputum color. Log inhaler use, oxygen saturation, peak flow, and flare patterns so your pulmonologist sees the full picture between spirometry appointments, not just the numbers from one good morning in the office. Built for people managing chronic obstructive pulmonary disease, emphysema, chronic bronchitis, alpha-1 antitrypsin deficiency, and the overlap of asthma-COPD (ACO) that blurs treatment decisions. BREATHING AND SYMPTOM TRACKING Capture COPD the way it actually shows up: - Breathlessness on a 1 to 10 scale - Peak flow and FEV1 readings - Oxygen saturation logging with pulse oximeter - Cough frequency and sputum color changes - Wheezing and chest tightness - Exercise tolerance and walking distance - Nighttime symptoms and sleep disruption - Fatigue and energy levels - Exacerbation onset and severity - Custom symptoms you define EXACERBATION LOG Catch flares before they land you in the ER: - Symptom escalation timeline - Sputum color and volume changes - Increased rescue inhaler use - Fever and infection signals - Action plan step triggered - ER visits and hospitalizations - Recovery duration tracking MEDICATION MANAGEMENT Track the full COPD regimen: - Maintenance inhalers like Breo Ellipta, Trelegy Ellipta, Symbicort, Advair - Long-acting bronchodilators like Spiriva, Incruse, Stiolto, Anoro - Rescue inhalers like albuterol, Ventolin, and Combivent - Nebulizer treatments and durations - Oral corticosteroids for exacerbations - Antibiotics during flares - Roflumilast and azithromycin prophylaxis - Supplemental oxygen hours and flow rate - Inhaler technique and adherence - Side effect monitoring - Refill reminders TRIGGER IDENTIFICATION Find what steals your breath: - Air quality index and pollution levels - Cold air and weather changes - Allergens and seasonal irritants - Smoke, fumes, and chemical exposure - Respiratory infections - Physical overexertion - Humidity and barometric pressure - Indoor air quality - Custom triggers you discover LIFESTYLE FACTORS The habits that protect your lungs: - Exercise minutes and pulmonary rehab sessions - Sleep quality and position - Nutrition and weight management - Hydration levels - Smoking cessation progress - Stress and anxiety levels INSIGHTS AND REPORTS Months of entries become real evidence for your care team: - FEV1 and peak flow trends over time - Exacerbation frequency and severity patterns - Rescue inhaler use trends - Trigger correlations ranked by frequency - Oxygen saturation patterns - Medication adherence and response curves - PDF and CSV exports for pulmonologists, respiratory therapists, and primary care DESIGNED FOR HARD-BREATHING DAYS - 30-second quick logging - Voice-to-text input when breathing is the priority - Clear visual charts for lung function trends - Apple Health sync for steps, heart rate, and oxygen - Gentle reminders for inhaler adherence - Optional biometric lock and offline mode HEALTH PATHWAYS - Pursed-lip and diaphragmatic breathing guides - Pulmonary rehab exercise logs - Energy conservation techniques - Plain-language education on COPD staging and GOLD classification COPD is not just being out of breath. COPD Tracker treats it like the progressive lung condition it is - helping you catch exacerbations early, prove inhaler adherence, and bring your pulmonologist spirometry-grade data from everyday life. Your health data belongs to you. COPD Tracker stores your information securely on your device and in your private cloud account. We do not sell or share it.
