Introducing Revitalize
Your vital signs.
In a single glance.
Heart rate, blood pressure, oxygen saturation and breathing rate — read from the light in your face by your iPhone's front camera. No cuff. No wearable. Nothing leaves your phone.
Actual app screens · readings shown are examples.
Every heartbeat leaves a trace.
Now your iPhone can see it.
Four vitals. One camera.
Everything a check-up starts with, from the phone already in your hand.
Heart rate
Each heartbeat sends a faint wave of colour through your cheeks. Revitalize finds its rhythm.
Blood pressure
Pulse shape and timing across both cheeks estimate systolic and diastolic — no cuff required.
Blood oxygen
How red and blue light are absorbed differently reveals how well your blood is carrying oxygen.
Breathing rate
The slow rise and fall underneath your pulse gives your breaths per minute.
Look. Light. Learn.
Remote photoplethysmography turns an ordinary camera into an optical sensor. Here is what happens in the moments you look at your screen.
-
1
Look
Face detection maps your features in real time and locks on to both cheeks — the skin where blood flow shows most clearly.
-
2
Light
Colour changes far too small for the eye are separated from motion and ambient light, then filtered into a clean pulse signal.
-
3
Learn
Neural networks trained on clinical research datasets read the signal and return your vitals — running entirely on your iPhone's chip.
The real scan, step by step.

Built by a physician
Held to the standard of the clinic.
Revitalize was designed by a practising attending physician and grounded in peer-reviewed research on camera-based vital signs. Accuracy is measured the way clinicians measure blood pressure devices — not by marketing.
Clinical validation study: in development.
Personal calibration
Pair a few readings with your own cuff, and Revitalize tunes its model to you.
Graded, not guessed
Every calibration is scored against the British Hypertension Society grading protocol, so you know how far to trust each reading.
A signal-quality check
Too dark, too much movement? Revitalize asks you to try again instead of showing a number it can't stand behind.
