Several pulse oximeters, one screen
Live SpO₂ and heart rate from up to eight Bluetooth fingertip oximeters, side by side on one phone, with an alarm when anyone drops below your threshold.
Why one app per sensor stops working
Bluetooth fingertip oximeters come with a free companion app built around one wearer: one sensor, one phone, one reading. That's fine for yourself. It falls apart the moment you want to watch a group — a coach at an altitude camp, an instructor running a breathwork session, a crew flying unpressurized — because you end up with a phone per person and no single place to look.
The alternatives are dedicated multi-sensor displays that cost hundreds of dollars, or quote-only group systems. MOMS is the gap in between: one app, the fingertip sensors you already own, and every reading on one screen.
How it works
Switch the sensors on
MOMS scans and connects on its own. There's no pairing in Bluetooth settings, and a sensor that drops out reconnects when it comes back.
One tile per sensor, up to eight
Each tile shows live SpO₂ and heart rate. Name it after its wearer and MOMS remembers the name next time.
Set your threshold
Pick an alarm level from 80 to 95%. A reading below it flashes the tile red and sounds a repeating alarm until it clears or you mute it.
Silent sensors don't hide
No data for five seconds raises its own alarm. A finger slipping out turns the tile yellow with a single chime.
Record the session
Each run is saved as one plain CSV file on your device. The review screen shows per-sensor summaries, SpO₂ and heart-rate charts, dip counts and a timeline of events.
Try it with no sensors
Demo mode simulates a full grid of eight sensors, dips and alarms included, so you can see every screen first.

Which oximeters work
MOMS speaks three Bluetooth protocols, and you can mix brands on the same screen:
- BerryMed BCI — BerryMed BM1000 family, Oxiline Pulse XS / X Pro and other BerryMed-based brands
- Viatom / Wellue A5 — Wellue O2Ring, WearPulse SA-10BW, OxyLink and similar sensors
- O2M (Wellue / Lepu) — Checkme O2 Max, which shows up as "O2M", and other Checkme O2 oximeters
Sensor-specific notes:
- Wellue O2Ring (Viatom / Wellue A5 protocol)
- BerryMed BM1000 (BerryMed BCI protocol)
- Checkme O2 Max (O2M (Wellue / Lepu) protocol)
Most of these sensors accept one Bluetooth connection at a time. If a sensor's own app is open and connected, close it before starting MOMS.
Questions
Do I need to pair each sensor?
No. Switch it on and MOMS finds it.
Can I mix brands?
Yes. Any combination of the supported sensors, up to eight at once.
Does it need the internet?
No. Everything works offline, and nothing is uploaded: there's no account and no Elevated Self server. Details in the privacy policy.
Does it keep running with the screen off?
Yes. On Android a persistent notification carries live readings; on iPhone, alarms arrive as notifications.
