Are you getting the most from your CPAP therapy? SleepScope gives you the insights your machine's tiny screen can't. Sync wirelessly. See everything. Sleep better. ▸ SYNC WITHOUT A COMPUTER Power on your CPAP, open SleepScope, and your latest therapy data transfers wirelessly via ezShare WiFi SD card. No cables, no desktop software, no cloud accounts. Your most recent night appears in seconds — older data syncs quietly in the background. ▸ SEE WHAT YOUR MACHINE CAN'T SHOW YOU Your CPAP displays a single AHI number. SleepScope shows you the full picture: • Exactly when apneas and hypopneas happened overnight • How your pressure, leak, and breathing changed hour by hour • Whether your mask seal held or broke down at 3 AM • Zoomable charts for every signal your machine records ▸ CONNECT YOUR HEALTH DATA Pair with Apple Health to see your CPAP therapy alongside heart rate, blood oxygen, sleep stages, and HRV from your Apple Watch or Garmin. Discover patterns your doctor will want to see. ▸ TRACK YOUR PROGRESS • AHI trends over weeks and months with severity zones • Insurance compliance tracking (4+ hours/night) • Leak trends to know when your mask needs replacing • Correlation charts: does higher AHI mean lower SpO2? ▸ DETECT SNORING Place your phone on your bedside table and SleepScope listens for snoring using on-device AI. No audio is ever recorded or stored — just timestamps and confidence scores. ▸ YOUR DATA, YOUR DEVICE SleepScope is built on a simple principle: health data belongs to you. • Everything stays on your iPhone — no cloud, no servers, no accounts • No ads, no tracking, no data selling — ever • GDPR compliant with explicit consent • Open your data anytime, delete it anytime ▸ BUILT BY A PATIENT, FOR PATIENTS SleepScope was created by a CPAP user who wanted OSCAR-level detail on iPhone.

Works with ResMed AirSense 10 & 11 via ezShare WiFi SD card.
