SpO₂ for a team at altitude camp
Up to eight fingertip oximeters on one phone: read a whole squad at once, set your own alarm level, and keep a record of every session. No signal needed.
A whole team, one screen
At an altitude camp, SpO₂ is one of the numbers coaches and guides like to see: a morning check before training, a reading after a hard session, a look at how a group's numbers move over the first days at elevation. With one fingertip oximeter and its own app per person, that means passing phones around and writing numbers down.
MOMS puts up to eight fingertip oximeters on one phone. Clip a sensor on each athlete, and every reading appears on its own tile, named after its wearer.
How a camp uses it
Morning check, all at once
Hand out the sensors, open MOMS, and read the whole group at the same time instead of one by one. Tiles keep their names, so the next morning the same sensor shows up as the same person.
Your own alarm threshold
Set an alarm level between 80 and 95%. A reading below it flashes the tile red and sounds a repeating alarm until it clears or you mute it. The level is yours to choose; MOMS doesn't pick one for you.
A record of every session
Each run is saved as a plain CSV file on the phone. The review screen shows per-sensor summaries, SpO₂ and heart-rate charts, dip counts and an event timeline, so you can compare day one with day five.
Made for remote places
No signal needed: MOMS works fully offline, with no account and no server. Sensors connect over Bluetooth with no pairing, and reconnect on their own if one drops out.
Sensors you can actually buy
Fingertip oximeters at US$20–80 each, mixed freely: BerryMed BM1000 family, Wellue O2Ring and Checkme O2 Max among them.
Silent sensors don't hide
A sensor with no data for five seconds raises its own alarm, and a finger slipping out turns the tile yellow, so a missing reading never looks like a good one.

What MOMS is, and isn't
MOMS shows the numbers your sensors report, side by side, and records them. It doesn't interpret them: it doesn't judge acclimatization, say whether anyone is fit to train or climb, or replace the judgement of the people responsible for the group. Fingertip readings are also affected by cold hands, movement and poor fit, which matters at altitude.
Which sensors work, and how to set them up: several pulse oximeters on one screen.
- Wellue O2Ring (Viatom / Wellue A5 protocol)
- BerryMed BM1000 (BerryMed BCI protocol)
- Checkme O2 Max (O2M (Wellue / Lepu) protocol)
