Stop guessing why you woke up tired.

Your CPAP app gives you a score out of 100. We show you the full story, right from your phone.

CPAP Analysis app showing sleep therapy summary

What a score out of 100 can't show you

When your breathing stopped

Your score averages the whole night into one number. But apnoeas cluster – a calm first half and a terrible 3 AM can look the same as a steady night. The difference matters.

The events behind your score

Central apnoeas, hypopnoeas, and obstructive events need different responses. Your score doesn't distinguish between them. Your data does.

Your therapy, night over night

A score that bounces between 90 and 95 tells you nothing. Seeing your trends night over night – event types, leak rates, pressure changes – tells you everything.

CPAP Analysis reads your therapy data. Nothing leaves your phone.

Understand

See your whole night – events, pressure, leaks, trends – with clear explanations.

Everything you need to understand your sleep

All the detail your CPAP app leaves out, without the complexity of clinical software.

Know exactly what woke you up

See your AHI hour by hour through the night. Spot the clusters of events that disrupt your sleep – not just a morning average.

Understand what's happening, not just that something happened

Every event – central, obstructive, hypopnea – mapped on a timeline with explanations. Know what each one means.

Track what's working

See your trends night over night. Leak rates, pressure, event breakdowns – so you know if that mask adjustment or pressure change actually helped.

Keep your data private

Everything is processed and stored on your iPhone. No servers, no accounts, no cloud. We literally cannot see your data.

Built out of sheer frustration.

My CPAP app gave me 98 out of 100. I felt terrible.

The raw data showed why: a huge spike in central apnoeas at 3 AM, buried in a nightly average that said everything was fine. But the only way to see this was pulling the SD card and booting up a laptop.

So I built CPAP Analysis. Plug in your SD card. See the truth from bed.

Your Data. Your Device.

Health data is deeply personal. CPAP Analysis never sends your data anywhere. We literally can't see it. Everything is processed and stored locally on your iPhone.

Built by a CPAP user, for CPAP users.

Frequently Asked Questions

What kind of adapter do I need for my iPhone?
If you have an iPhone 15 or newer, any cheap USB-C to SD Card reader will work perfectly (affiliate link). If you have an iPhone 14 or older, you will need a Lightning to SD Card Camera Reader (Apple's official one is great, but third-party ones work too).
Will this delete or mess up the data on my SD card?
Absolutely not. CPAP Analysis is strictly a "read-only" app. It looks at the files to generate your charts and stores them securely on your device, but it never alters or deletes the files on your physical card. Your data remains perfectly safe for your doctor.
Which CPAP machines are supported?
CPAP Analysis works with most ResMed machines. If you have a different manufacturer's machine, please get in touch – we'd love to hear from you.
