Blood pressure log

A phone camera cannot measure blood pressure reliably, so PulseCam doesn't guess. Enter readings from an upper-arm cuff to track and classify them here.

    Heart-rate history

      For a good reading

      1. Sit still, relax, rest your hand on a table.
      2. Phones with 2-3 rear lenses: use the main camera, the biggest lens right next to the flash. Cover that lens and the flash together with the pad of your fingertip. If the torch doesn't light up, tap 🔄 to try the next lens.
      3. Press gently. Pressing hard cuts off the blood flow.
      4. Hold still for about 30 seconds until the ring fills.

      Questions

      How can a camera read my pulse?

      With the torch on, your fingertip glows red. Every heartbeat changes how much light passes through, and the camera sees those tiny colour changes. PulseCam filters the signal and finds the rhythm. This technique is called photoplethysmography (PPG).

      Can it measure blood pressure?

      No. A phone camera can't measure blood pressure reliably, so PulseCam doesn't guess. Use the log to record and classify readings from an arm cuff.

      Is it a medical device?

      No. It is for fitness and curiosity only. Don't use it to diagnose or monitor a condition; talk to a doctor about health concerns.

      Is my data private?

      Yes. Video is processed on your device and never uploaded. Saved readings stay in your browser and you can delete them at any time.

      Does it work on iPhone?

      The measurement works, but iPhone Safari can't switch the torch on from a web page, so use a bright light. On Chrome for Android the torch turns on automatically.

      Made by Blockium Solutions. PulseCam detects tiny colour changes as blood pulses through your fingertip (photoplethysmography). For fitness and curiosity only. It is not a medical device and must not be used to diagnose or monitor a condition. Video never leaves your device; readings are stored only in this browser. Torch control works in Chrome on Android. iPhone Safari can't switch the torch on from a web page, so use a bright light there.
