Tired of dragging your SD card to a laptop every morning? Had grand plans to check your CPAP data daily, but gave up because the routine was a pain? Me too. That's why I built CPAP Analysis. Plug your SD card into your iPhone before you get out of bed. Sync your data in seconds, then check it in bed or later over coffee, at work, on the toilet - we won't judge. See everything your machine recorded: • Detailed event timeline for every night • Events split by type – obstructive, central, hypopnea, CSR • Blood oxygen and pulse with compatible devices • Leaks, pressure, respiratory rate, tidal volume, minute ventilation Zoom out and spot trends over weeks and months. APPLE HEALTH INTEGRATION Wear an Apple Watch or use a sleep tracking app? See your sleep stages, SpO2 and pulse alongside your CPAP data. WEAR AN O2 RING? Any ring that syncs SpO2 to Apple Health (Wellue O2Ring and similar) overlays your overnight oxygen and pulse on every night automatically. COLLECT AWARDS Earn collectible cards for streaks, records and clean nights. SHARE WITH OTHERS Need help understanding your data? Share live graphs directly from the app, so you can ask for support in expert communities. BUILT BY A CPAP USER No matter how hard I tried, I couldn't keep up the laptop data import routine. And I wasn't happy with my personal sleep data being sent to someone else's servers. So I built this. Now I leave an SD card reader in my bedside table, quickly sync when I wake up, then check the data later in the day. No more feeling guilty about meaning to check but never getting round to it. YOUR THERAPY DATA STAYS YOURS No accounts. No 30-day data caps. Your entire CPAP history lives on your device and your private iCloud – we never see it. WHAT YOU NEED • A ResMed CPAP machine that writes to an SD card • A Lightning or USB-C SD card reader ($10-15 easy to find online) • Optional: an Apple Watch or O2 ring that syncs to Apple Health for overnight SpO2 Not affiliated with ResMed or any other CPAP manufacturer. This app is not a medical device and does not provide medical advice. It displays data from your CPAP SD card for informational purposes only. Always consult your healthcare provider for guidance on your therapy.
