Why Most People Miss The Warning Signs
When blood oxygen starts to fall, you don't feel breathless straight away. You feel tired, a little foggy.
By the time breathlessness hits, your SpO₂ may already be in a dangerous range. And the reading your doctor takes in a warm waiting room tells almost nothing about what's happening at night, during activity, or hours after a hard day.
Normal SpO₂ is 95–100%. Below 90% needs urgent attention.
1 in 4 COPD patients have unnoticed overnight oxygen drops.
One clinic reading shows 1%. 30 days of home readings provide your doctor the info to adjust your care.
Every Detail Built for Real People
No medical degree required. No fumbling with apps or cables. Just clip on, press start, and read.
Smart Alarm Alerts
The alarm triggers the moment your SpO₂ or pulse rate moves outside safe range, day or night, before you ever feel it. For anyone managing COPD, sleep apnea, heart conditions, or post-surgical recovery, this is the feature that changes everything.
"Without this alarm I'd have gone months not knowing I had sleep apnea. It found something my GP hadn't flagged in three years of checkups."

Dual-Color OLED · 6 Display Modes
SpO₂ in teal. Pulse rate in amber. A live waveform so you can see the reading quality, not just the number. Six orientations means it's legible lying down, sitting up, or clipped to a lanyard, a detail that matters at 2am.
"I have macular degeneration. I can read this screen from across the room without squinting. My daughter nearly cried when she saw how clearly I could read it."

Clinical-Grade Accuracy
±2% SpO₂ accuracy in the clinical range. ±1 BPM pulse rate. The same specification standard as hospital-grade devices. When you log 30 days at home and walk in with the numbers, your doctor stops guessing and starts adjusting.
"She compared it to the clinic device. Within 1%. She adjusted my treatment based on overnight trend data, something she'd never been able to do before."
