- Cannot monitor blood oxygen at home
- Unaware of respiratory issues during sleep
- No quick vital signs check without visiting clinic
- Need for multi-device health tracking
More than a pulse oximeter
- 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.
The numbers that matter
- FDA+CEdual clearance
- 4in1SpO2, PR, PI, RR
- ±2%SpO2 range 70‑99%
- 4×rotatable OLED views
Ready in 3 seconds
- 1Insert 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.
- 2Press the power button
A single click activates the OLED display. Keep your hand still and relaxed for the most stable reading.
- 3Read your vitals
Within 8 seconds, the screen shows SpO2, pulse rate, perfusion index, and respiratory frequency. The waveform confirms data quality.
- 4Rotate the display
Hold the button to cycle through four viewing modes: waveform, big-number, multi‑parameter grid, and split screen. The orientation auto‑adjusts.
- 5Clip and go
Attach the included lanyard to the built‑in slot for hands‑free carrying. Ideal for bedside, gym bag, or travel pouch.

The moment you take control

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

Questions and answers
Absolutely. The device tracks oxygen saturation and respiratory rate continuously, making it perfect for overnight monitoring. Wearing it while you sleep can reveal periodic dips in SpO2 that often point to sleep‑disordered breathing. Note that it is not a diagnostic device on its own — always share the data with your physician for a formal assessment.
It runs on two standard AAA batteries (included). Under regular daily use, a pair of fresh alkaline batteries lasts about 30 hours of continuous operation. The OLED screen has an auto‑off timer to preserve battery life, and a low‑battery indicator gives you a heads‑up before they run out.
For best accuracy, hands should be warm and relaxed. Very cold fingers or dark nail polish (especially black or navy) can interfere with the optical sensor. We recommend removing nail polish and warming your hand if readings seem off. The device works well on lighter polish shades and most natural nails.
None at all. Open the clip, insert your finger, and press the power button. Within seconds, you’ll see your SpO2 and pulse on the main screen. The four display modes and auto‑rotation are intuitive — most people figure them out in under a minute.
Brief use during or after exercise works well, but motion artifacts may affect readings. For the most stable data, pause movement, place your hand on a steady surface, and remain still for the 8‑second reading window. Many athletes use it post‑workout to track recovery trends.
