Luna G3 data in Apnealytics

Not yet — waitlist. The Luna G3, made by BMC and sold in the United States by React Health (formerly 3B Medical), is not supported in Apnealytics and a parser is not in development. It is on the waitlist. Sign-ups on this page decide when work begins. Below: what the Luna G3 records, where its card is, what Apnealytics would show for Luna G3 data, and how to join.

Where the SD card is

The card slot is on the side of the machine. Turn the machine off and press the card to release it. Keep a card in at all times. Detailed data is written only to the card; if support ships, that card is your history.

Turn the Luna G3 off and remove the SD card.
Place it in a reader on your computer
Card import is web-only.
Sign in at my.apnealytics.com and open Import.
Drag the whole card folder onto the drop zone
Files travel directly to private storage on Cloudflare R2 and resume after interruptions.
Nights are parsed and deduplicated.

Import in five steps (if and when support ships)

What you'll see (if support ships)

Nightly AHI and event composition
The Luna G3 records apneas, hypopneas and flow limitation. These would appear in Apnealytics' event composition with the AHI band on each night.
Pressure and Reslex
Auto nights would show pressure percentiles against the set range with the Reslex level alongside.
Leak and Mask Analytics
Leak as the Luna G3 records it, labelled by BMC's definition, compared per mask in Mask Analytics. Pro waveforms depend on whether the Luna G3 writes high-resolution flow data to its card.

Five-step import diagram for the Luna G3: power off and remove card, reader on your computer, drag the whole card folder (Luna card folder), browser straight to private R2 storage, files stored now and turned into nights by Re-process when the parser ships (Waitlist badge)

Why it is on the waitlist

We build in order of demand and feasibility. The Luna G3's format is proprietary and, while the machine is common, requests have so far been fewer than for the machines already supported. Each sign-up on this page is counted. When the Luna G3 reaches the front of the queue, this page changes to "in development" and you get an email.

In the meantime: SleepHQ lists BMC among its supported brands. OSCAR's support for BMC machines is limited. React Health's Luna app shows a nightly summary.

Status card: Waitlist badge, BMC / React Health Luna G3, 'Not in development yet. Join the list; demand sets our order. If you can share a Luna G3 card for testing, write to info@apnealytics.com.'

FAQ

Questions people ask

Help center →

Does Apnealytics work with the Luna G3?

Not yet, and it is not in development. The Luna G3 is on the waitlist. Join on this page or in the compatibility checker and we will email you when work starts. You can use Apnealytics now for mask tracking, replacement reminders, Apple Health or Health Connect vitals, and oximeter overlays on Pro.

Is the Luna G3 a BMC, 3B Medical or React Health machine?

All three names refer to the same device. BMC Medical in China manufactures it; 3B Medical distributed it in the US; React Health acquired 3B Medical and now sells it under the React Health name. Apnealytics lists it as BMC / React Health so any search finds it.

Can Apnealytics read the Luna app or the Luna cloud?

No. These are React Health's own services and are not open to third parties. If support ships, Apnealytics will read the SD card directly.

What can I use for Luna G3 data today?

SleepHQ lists BMC among its five supported brands. React Health's own app shows a nightly summary. OSCAR's Luna support is limited. Keep your cards; if Apnealytics ships support you will be able to import the history.

Does joining the waitlist commit me to anything?

No. It is a free email sign-up, or simply adding the machine to your gear on a free account. If support ships, the Luna G3 will be supported on the Free plan like ResMed machines: unlimited imports and the last 30 nights, with full history and waveforms on Pro.
