CPAPdata vs myAir
ResMed's own free app
If you have a ResMed AirSense 10 or 11, you probably already have myAir. It sends your night over the cellular connection by itself and gives you a score out of 100 each morning. It is well made and it works. It also shows you almost none of what your machine actually recorded, which is why people who want to understand their therapy end up looking for something else.
Which one should you use
Keep using myAir if
You want a daily nudge that takes zero effort. The score is a good habit-forming device, the sync is invisible, and for someone whose therapy is stable and comfortable that may be all the feedback they ever need. There is no reason to stop using it.
Add CPAPdata if
Your score is good and you still feel tired, or your score dropped and you want to know which of the four components moved and why. That question cannot be answered inside myAir, because the numbers behind the score are not shown there.
| Criterion | myAir | CPAPdata |
|---|---|---|
| Price | Free | Access with a verified account, pricing announced at launch |
| Effort | None, it syncs by itself | You supply the SD card, for now |
| What you see | A score out of 100 and four summary figures | The measured values behind them |
| Event types | One events-per-hour figure | Obstructive, central and hypopnea separately |
| Leak detail | A mask-seal rating | Leak rate, 95th percentile, time over the threshold |
| Pressure statistics | Not shown | Median, 95th percentile, maximum |
| Flow limitation | Not shown | Yes |
| Machines supported | ResMed AirSense and AirCurve only | ResMed today, Löwenstein and Philips next |
What the myAir score is made of
The score combines usage hours, mask seal, events per hour and how often you took the mask off. Usage carries most of the weight, which is deliberate: the app exists partly to encourage adherence, and adherence is the thing most likely to be a problem in the first months.
That design makes it a good motivational tool and a poor diagnostic one. A high score mostly tells you that you wore it a long time with a decent seal, which is worth knowing but is not the same as the therapy working well.
The questions myAir cannot answer
It gives you one events-per-hour figure. It does not separate obstructive events from central ones, and that distinction changes what the finding means and what your doctor would do about it. It also does not show flow limitation at all, which is the usual explanation for feeling unrefreshed despite an excellent score.
The same goes for pressure. myAir does not show what pressure your machine actually delivered, so if you are on an auto-adjusting device you cannot see the 95th percentile that describes what your airway needed. All of this is written to the SD card every night. It is just not in the app.
The two work well together
Most people should keep myAir. It costs nothing, requires nothing, and the daily score is a reasonable early warning that something changed. Use it as the signal.
Then, when it does change, read the card. That is the split we would recommend even if we did not build one of the two: an effortless daily indicator, plus a real look at the data when the indicator moves.
Common questions
Why is my myAir score high when I still feel tired?
+
The score is weighted towards how long you wore the mask and how well it sealed. It does not include flow limitation, and it does not distinguish central from obstructive events. Both are common explanations for unrefreshing sleep with a good score, and both are on the SD card.
Does myAir show the same data as the SD card?
+
No. The card holds the full detailed record, including waveforms, pressure statistics and event types. myAir shows a summary built from part of it. Reading the card is the only way to see the rest.
