Lung Logger

Lung Logger is a free lung health tracking app built by a double lung transplant patient for people who monitor their breathing, recovery, and daily health at home. Use Lung Logger to record and review important recovery numbers over time, including FEV1, peak expiratory flow (PEF), blood pressure, pulse, weight, temperature, exercise, activities, and health events. Lung Logger is useful for: Lung transplant recipients People waiting for a lung transplant People with chronic lung disease People tracking pulmonary health at home Patients who use home spirometry or peak flow meters People who want clear records to share with their care team Track home spirometry readings Lung Logger can help you track FEV1 and PEF trends from your own home spirometry or peak flow device. The app does not measure lung function by itself. You enter readings from your own device, then Lung Logger helps organize those numbers into clear charts and reports. Log daily vitals and recovery activity You can also use Lung Logger without a spirometry device to track daily vitals, weight, temperature, blood pressure, pulse, exercise, breathing exercises, stretching, light activity, and recovery notes. Watch trends over time Charts make it easier to see changes in your lung function, vitals, and recovery patterns. This can help you notice when numbers are improving, staying steady, or changing in a way you may want to discuss with your doctor. Share reports with your care team Export organized health summaries so your doctor, transplant team, pulmonologist, or respiratory therapist can review your data without sorting through handwritten notes. Built for real recovery Lung Logger was created from the daily tracking needs of a lung transplant patient. It is designed to be simple, focused, and useful for people managing pulmonary recovery at home. Lung Logger is not a medical device and does not diagnose, treat, or prevent disease. Always follow your care team’s instructions and contact your healthcare provider if your symptoms or numbers change.
