Removed: SpO₂, BP, MAP, cardiac output
These are no longer produced from the camera; the report marks them “not measured by camera”. Vascular age is gone too.
Free wellness scan · no signup · no hardware
Your heart rate, HRV and breathing — from a 35-second face scan.
Vital Scan reads the tiny colour changes in your face that follow each heartbeat, using the camera you already have. It shows only what the camera can honestly measure, and says “not measured” when it can’t. Free, in your browser, with a PDF report at the end.

New · the v6 engine (September 2026)
We took numbers out — on purpose.
Face-scan apps often show oxygen and blood-pressure figures that a phone camera can’t truly measure. In the current engine we removed them. Vital Scan now shows what the camera can measure, and tells you plainly when a reading isn’t reliable enough to show.
Try the new engineHRV and breathing, only when reliable
HRV and respiration appear only when the pulse signal is clean enough. Otherwise you see “not measured”, not a guess.
Warm-up before the countdown
The face tracker settles before the 35-second clock starts, so the scan time is spent on signal, not set-up.
Honest failure messages
If light or movement spoils the signal, the scan says so and asks you to try again. It won’t invent a result.
What the camera measures today
Three readings. Each one earned from the signal.
Heart rate comes straight from the pulse wave in your face. Heart-rate variability and breathing rate need a cleaner signal, so they appear only when the engine trusts it.
Heart rate
Beats per minute, taken from the dominant rhythm in the colour signal of the skin on your face.
Heart-rate variability
The beat-to-beat variation, reported as RMSSD, SDNN, pNN50 and mean RR interval. Shown only when the beats are clean enough to time.
Respiration
Breaths per minute, derived from the same facial pulse signal. Shown only when the breathing pattern is clear.
Not measured by camera
What Vital Scan does not give you
A phone camera isn’t a cuff or an oximeter, so the scan does not produce these. If you need them, use a proper device or see a clinician.
SpO₂ (oxygen)Blood pressureMean arterial pressureCardiac outputVascular ageHeart rhythm / AF
Calculated, not measured
Figures from details you type in
Your report may also show simple figures worked out from details you enter, such as height, weight and age (BMI, for example). They are labelled Calculated so you can tell them apart from camera readings. They are arithmetic, not measurements.
Every result carries its label, so you always know where a number came from.
Remote photoplethysmography (rPPG)
How a camera sees a pulse.
Each heartbeat pushes a little more blood into the skin of your face and changes its colour very slightly. Your eyes can’t see it, but a camera can. Vital Scan turns that change into a pulse wave in five steps, inside your browser.
01
Find the face
Face landmarks lock onto the skin areas of your face that carry the clearest signal.
02
Read the colour
The average skin colour of those areas is sampled frame by frame.
03
Extract the pulse
Two established rPPG methods, POS and CHROM, separate the pulse from lighting and movement.
04
Clean the signal
A band-pass filter keeps only frequencies that a heartbeat can produce.
05
Find the rhythm
Spectral analysis (Welch) finds the heart rate. HRV and breathing are added only when the signal is clean.
The scan runs in your browser. Face video is processed on your device or on our own servers. It is not sent to third-party AI services.
How it works
Four steps. About a minute.
No app to install and no account to create. You need a device with a camera, a reasonably lit room, and 35 seconds of sitting still.
Tips for a clean reading
- Face soft, even light; avoid a bright window behind you
- Keep your face inside the frame and stay still
- Breathe normally and don’t talk during the countdown
- Prop the phone or laptop up so it doesn’t move
-
Open the free scan
Go to instapraxis.instadatahelp.com/scan.html on a laptop or phone. There is nothing to sign up for.
-
Allow the camera
Your browser asks for camera permission. The face tracker warms up and locks on before the clock starts.
-
Hold still for 35 seconds
Look at the screen and breathe normally while the countdown runs and the pulse wave builds.
-
See your readings and the PDF
You get heart rate, plus HRV and breathing rate if the signal was clean, each with its label. Download the PDF report if you want a copy.
Try the honesty rule
Bad signal? You get “not measured”, not a guess.
Change the conditions to see how the report responds. With a clean signal, all three readings appear. With a shaky one, HRV and breathing drop out. If the signal is too poor, the scan says so and asks you to try again.
Simulation for illustration only. The numbers are examples, not anyone’s results.
Soft, even light and a still face: the pulse signal is clean, so all three readings are shown.

The scan couldn’t get a clean pulse signal. Move to even light, keep your face in the frame and hold still, then try again.
Where it fits
A quick wellness check-in, anywhere there’s a camera.
Vital Scan is a screening and awareness tool. It doesn’t replace clinical instruments or a doctor’s examination, but it makes a first check-in easy to offer.
Health camps and outreach
Give each visitor a quick, contact-free heart-rate and breathing check-in on a phone or laptop while they wait for the camp doctor.
Wellness centres and gyms
Offer members a free check-in before a session and a PDF to take home. A friendly way to start a conversation about habits.
Workplace wellness days
Set up a laptop at the wellness stall. Staff can scan in about a minute without registering.
Clinic waiting rooms
With InstaPraxis, patients can self-scan from the Health Scans portal and their doctor can see the report.
Video consultations
Inside InstaPraxis, a doctor can start the patient’s Vital Scan during the call and see the readings as they arrive.

FAQ
Questions about Vital Scan
What does Vital Scan measure?
From a 35-second face scan, the camera measures your heart rate. Heart-rate variability (RMSSD, SDNN, pNN50 and mean RR interval) and breathing rate are shown when the pulse signal is reliable enough; otherwise they are marked “not measured”. Any figures worked out from details you type in, such as BMI, are labelled as calculated, not measured.
Does Vital Scan measure SpO₂ or blood pressure?
No. The current engine does not produce SpO₂, blood pressure, mean arterial pressure or cardiac output from the camera, and the report marks them “not measured by camera”. If you need those readings, use a validated pulse oximeter or blood-pressure monitor.
Is Vital Scan really free? Do I need to sign up?
Yes, it is free and there is no sign-up. Open instapraxis.instadatahelp.com/scan.html, allow camera access and follow the on-screen steps. You can download a PDF report at the end.
How can a camera measure heart rate?
It uses remote photoplethysmography (rPPG). Each heartbeat changes the colour of your facial skin very slightly. Vital Scan tracks your face, samples the skin colour frame by frame, separates the pulse from lighting and movement with the POS and CHROM methods, filters it, and finds the heart rate with spectral analysis.
Is Vital Scan a medical device or a diagnosis?
No. Vital Scan is a free wellness screening for general awareness. It is not a medical device and does not diagnose, treat or rule out any condition. Inside InstaPraxis, scan results are decision-support for a registered medical practitioner. A CDSCO Class B readiness file for our AI scans is in preparation; nothing has been filed.
Why did my scan show “not measured” or ask me to try again?
HRV and breathing need a clean pulse signal, so they are hidden when movement or poor light makes the signal unreliable. If the signal is too poor even for heart rate, the scan tells you and asks you to retry. Sit in soft, even light, keep your face in the frame, stay still and don’t talk during the countdown.
What happens to my face video?
The scan runs in your browser. Face video is processed on your device or on our own servers, and it is not sent to third-party AI services.
Does Vital Scan check for irregular heart rhythm?
No. A rhythm index has been built but stays switched off until it has been calibrated against ECG, so Vital Scan does not report on heart rhythm.
Can my clinic use Vital Scan with patients?
Yes, through InstaPraxis, our AI-first clinic platform. The same engine runs there alongside eight other AI screening scans. Doctors can start a patient’s scan during a video consultation, and patients can self-scan from the Health Scans portal. InstaPraxis costs ₹399 per doctor per month with all AI features, plus ₹15 per prescription, and you can start with a 30-day pilot.
Take the scan. It’s 35 seconds and free.
