Hey Product Hunt! 👋 I built this app because my family member was diagnosed with COPD and struggled to keep track of all the different metrics — lung function reports, daily SpO₂, symptom scores, medications. Paper records got lost, and existing apps either required signup or uploaded health data to the cloud. This app is: - 🆓 100% free, no ads, no subscriptions - 🔒 All data stays on your phone (SQLite) - 📱 Works on both iOS and Android - 🌐 Fully offline — no internet needed It's open source too! Would love your feedback and feature suggestions. 🙏
