Know every breath in real time
One FDA-certified device reads your oxygen, pulse, perfusion, and respiratory rate — so you stop guessing and start understanding.
The moment you take control
From anxious glances at clinic numbers to owning your daily wellness — this is how one small device changes everything.
The unknowns between appointments
You feel a dip in energy, a restless night, a racing heart — but without a lab, you’re left wondering. Tracking your vitals shouldn’t mean scheduling a visit every time. Yet most of us wait weeks between doctor’s checks, missing the subtle shifts our bodies whisper daily. Sleep quality and respiratory patterns stay invisible until a crisis forces them into the spotlight.
The discovery that fits in your pocket
When a colleague showed me their wellness tracker, I expected another wrist gadget. Instead, it was this — a finger-clip device reading four vital signs in under 3 seconds. FDA-cleared, CE-certified, and so compact it clips to a lanyard. Suddenly, the data I’d been guessing about was right there: oxygen saturation, pulse, perfusion strength, even breath frequency — all on a bright OLED screen. No subscriptions, no apps, no complexity.
The empowered life
Now I check each morning — 30 seconds, and I know my oxygen and perfusion baseline. Overnight monitoring flags breathing pauses I’d never have noticed, giving me a head start on sleep apnea conversations with my doctor. Post-workout recovery numbers let me fine-tune hydration and rest. And when my father’s pulse oximeter reading dipped, the early catch brought paramedics before he felt a thing. This isn’t a gadget — it’s daily peace.
More than a pulse oximeter
It’s a personal health dashboard — clinical precision in a compact clip.
SpO2, pulse, perfusion, and respiratory rate
Most oximeters give you only two numbers. This one delivers a full panel — blood oxygen saturation, pulse rate, perfusion index (an indicator of circulation), and respiratory frequency. That’s the difference between a snapshot and a story. Ideal for fitness recovery, chronic condition monitoring, and sleep screening — all from one finger.
Rotatable views, glanceable clarity
The bright OLED screen lets you flip between four display modes — show a waveform, large single-number, or multi-parameter grid. Orientation auto-adjusts, so you can read it left‑handed, right‑handed, or clipped to a home safety kit. No squinting, no guessing.
FDA & CE certified, lab‑grade accuracy
Every component — from the soft-touch silicone finger rest to the optical sensor — is built to meet clinical certification standards. SpO2 accuracy of ±2% under normal conditions means your readings mirror what a medical professional would trust. Use it daily; it stays consistent.
Ready in 3 seconds
Clip, press, read — repeat daily.
- 01
Insert your finger
Place a clean, dry finger into the soft silicone clip — index or middle finger works best. Make sure the nail is facing the top cover.
- 02
Press the power button
A single click activates the OLED display. Keep your hand still and relaxed for the most stable reading.
- 03
Read your vitals
Within 8 seconds, the screen shows SpO2, pulse rate, perfusion index, and respiratory frequency. The waveform confirms data quality.
- 04
Rotate the display
Hold the button to cycle through four viewing modes: waveform, big-number, multi‑parameter grid, and split screen. The orientation auto‑adjusts.
- 05
Clip and go
Attach the included lanyard to the built‑in slot for hands‑free carrying. Ideal for bedside, gym bag, or travel pouch.

Keep it accurate
Simple maintenance for years of reliable service.
- Clean after each useWipe the finger chamber and silicone rest with a 70% alcohol swab. Let dry completely before storing.
- Store in a cool, dry placeAvoid direct sunlight, extreme humidity, or temperatures above 50°C (122°F).
- Remove batteries if stored long‑termTo prevent corrosion, take out AAA batteries if you won’t use the device for more than a month.
- Handle with careThis is a precision optical instrument. Avoid dropping or crushing; the clip mechanism is durable but not indestructible.

What they say
Checked my father after his cough worsened — oxygen was 89%. We got him to urgent care within the hour. This little device gave us hours of lead time.
As an endurance runner, perfusion index tells me when I’m recovering well. The lanyard means I clip it on my vest — no lost device mid‑trail.
Perfect for travel. I packed it for a recent altitude trip — watching my SpO2 adjust day by day was reassuring and fascinating.
No subscription, no app, no complexity. Just clip it on and get what I need. Finally, something that respects my privacy.

I use it every morning to track my SpO2 and perfusion index. The numbers are fast, consistent, and the OLED screen is crystal clear. Better than the $200 one my clinic uses.
Great for peace of mind with my elderly mom. She keeps it on her nightstand, and we check together via video call. So simple, even she got the hang of it.
Rotating display modes are a real-world win. I prefer the large-number view for quick checks; waveform when I’m logging data. Smart design.
Used it after a long flight — caught a slight O2 dip and took it easy the rest of the day. It saved me from crashing hard.

Discovered my respiratory rate drops during certain sleep positions. My sleep specialist said the data was invaluable. Worth every cent.
Pulse oximeters I’ve tried before froze or gave inconsistent readings. This one has a solid chip that stays accurate. The battery indicator is a nice touch.
My doctor appreciated the consistent readings when I brought it in for calibration. He said it matched his hand‑held monitor precisely.
Bought one for my dad and one for myself. We both love the soft silicone finger rest — no pinching, even for my larger hand.
