Heart Rate Monitor - Pulse PRO
Overview
Heart Rate Monitor - Pulse Rate, published by AirShape / Wellmy, turns standard smartphone camera hardware into an optical cardiac monitoring tool. The application utilizes Photoplethysmography (PPG), an optical measurement method used in clinical pulse oximetry and standard health monitors. By placing an index finger over the smartphone's camera lens while the LED flash illuminates the underlying skin, the camera registers minor color changes caused by blood volume pulses in peripheral capillaries.
The physics of PPG relies on light absorption properties. Oxygenated blood absorbs green light preferentially and reflects red light. During heart contraction (systole), blood surges into capillary beds, increasing light absorption. During cardiac relaxation (diastole), capillary blood volume drops, altering light absorption. The application's AI algorithms filter the resulting video frame data, isolating pulsatile signals to compute pulse rate in Beats Per Minute (BPM) within 5 to 10 seconds.
In addition to camera-based pulse checking, the application provides a health diary for logging blood pressure measurements, activity tags (e.g., resting, post-workout, elevated stress), and daily vitals. Visual graph displays plot historical measurements over time, making it easy to summarize vital sign trends for routine checkups or doctor visits.

FAQs
How does my smartphone camera measure my heart rate?
The app uses the camera and LED flash to detect micro-color changes in your finger as blood pulses through peripheral capillaries, using AI algorithms to calculate your pulse rate.
Is the heart rate reading accurate enough for medical diagnoses?
No, while PPG technology provides reliable spot-check estimates, the app is intended for general fitness tracking and is not a certified medical device.
Why do I need to cover the LED camera flash with my finger?
The LED flash illuminates the capillary bed beneath your skin, providing the light contrast necessary for the camera sensor to detect micro-volume blood changes.
Does the app automatically track blood pressure through the camera?
No, blood pressure metrics are entered manually into the vital signs log, which then tracks trends alongside your camera-measured heart rate.
How should I position my finger to get the most accurate PPG reading?
Place your index fingertip lightly over the rear camera lens and flash without pressing too hard, remaining still and silent throughout the 10-second scan.
