you already carry.
Pulsira uses your phone or laptop camera to read the tiny color changes that follow each heartbeat. It checks signal quality first and shows a number second, all privately on your own device.

How a reading works
Three calm steps.
Designed to feel like a quick check-in, not a test.
Hold still
While you rest, Pulsira checks brightness and motion, and waits until the signal is clean enough to use.
See your reading
Your estimate appears with its signal quality beside it. Save it locally or export it, nothing more.
Inside the app
A clean workspace for every reading.
- Measure. Live waveform, signal quality and an experimental estimate.
- Validation lab. Compare a reading against a reference device you already own.
- Session history. Kept on your device, exportable as a file any time.
- Privacy & limits. Plain-language notes on what the app can and can’t do.
Private by design
Your camera, your device, your data.

Wellness first. Honest about limits.
Pulsira is a general wellness tool. Its estimates have not been clinically validated, and it is not a medical device. It should never be used for diagnosis, monitoring a condition, medication decisions or emergencies. If you feel unwell, contact a healthcare professional.

Questions
Good to know.
How can a camera read a pulse?
Each heartbeat changes how much light your skin absorbs, very slightly. The camera sees those tiny color shifts, and Pulsira turns them into a waveform. The technique is called photoplethysmography (PPG).
Is it accurate?
Results depend on light, motion and your device, which is why Pulsira shows signal quality with every reading. Its estimates are experimental and have not been clinically validated.
Does it store my video?
No. Frames are processed in your browser and discarded. Only the reading itself (time, estimate, quality) is saved, and only on your device.
