The Best Way to Analyze Your CPAP Data Online
Compare CPAP data analysis options — OSCAR, myAir, SleepHQ, and CPAP Clarity. Find the right tool for your needs.
Why Analyze Your CPAP Data?
Your CPAP machine records incredibly detailed information every night — far more than the simple AHI number on its screen. Analyzing this data helps you:
- Understand your therapy — See exactly what's happening while you sleep
- Identify problems early — Catch rising leak rates or increasing AHI before they become serious
- Have informed conversations with your doctor — Bring data, not just symptoms
- Optimize your setup — Find the best mask, pressure, and settings for you
But you need the right tool. Here's how the options compare.
The Options
ResMed myAir
What it is: ResMed's official companion app. Free, connected via Bluetooth or cellular.
Pros:
- Convenient — syncs automatically
- Simple daily score out of 100
- Basic compliance tracking
Limitations:
- Heavily simplified — the "score" system hides important details
- Known to inflate results (some users report "100/100" with clinically significant AHI)
- No detailed event breakdown or timing
- No leak rate graphs or pressure curves
- No data export
- ResMed devices only (obviously)
Best for: Users who want a quick daily check without any technical depth.
OSCAR (Open Source CPAP Analysis Reporter)
What it is: Free, open-source desktop application. The gold standard for detailed CPAP analysis.
Pros:
- Incredibly detailed — breath-by-breath waveforms, every metric imaginable
- Supports multiple machine brands
- Active community on apneaboard.com
- Completely free
Limitations:
- Desktop only — no mobile or web version
- Steep learning curve — the interface is dense and intimidating for beginners
- Dated UI — Qt-based interface from the early 2010s
- Manual import — must physically remove SD card and connect to computer
- Slow development — maintained by a small group of volunteers
- No insights or explanations — shows you the data but doesn't help you understand it
Best for: Power users who want maximum detail and are willing to invest time learning the interface.
SleepHQ
What it is: Commercial web-based CPAP analysis tool with a subscription model.
Pros:
- Modern web interface
- Cloud storage and syncing
- SD card uploader hardware available
Limitations:
- $15/month subscription for full features

- Less detailed than OSCAR for advanced analysis
Best for: Users who want a modern interface and are willing to pay a monthly subscription.
CPAP Clarity
What it is: Free, privacy-first web app for CPAP data analysis with smart insights.
Pros:
- Free forever — no subscription, no account needed
- Privacy-first — all data processing happens in your browser; your health data never leaves your device
- Beautiful, modern interface — designed for clarity, not complexity
- Smart insights — plain-English explanations of what your data means

- Instant results — drag and drop your SD card folder
Limitations:
- ResMed AirSense 10/11 only (for now)

- Newer tool — still adding features
Best for: Users who want to understand their data without a learning curve, with zero privacy compromise.

Stick with myAir only if you just want to confirm you used your machine last night and nothing more.
