HeartLog - Heart Rate Monitor

Heart Rate Monitor lets you measure your heart rate anytime, anywhere — no wearable required. Simply place your fingertip over the camera and flash, and the app detects subtle changes in blood flow to calculate your pulse in seconds.

HOW IT WORKS The app uses your phone's camera and flash to detect tiny color changes in your fingertip caused by each heartbeat. This technique, known as photoplethysmography (PPG), is the same method used in medical pulse oximeters.

FEATURES • Instant measurement — results in about 30 seconds • Measurement history — review all past readings at a glance • Heart rate categories — readings are labeled Low, Normal, Elevated, or High • Clean, distraction-free interface • Supports English, Simplified Chinese, and Traditional Chinese

IMPORTANT NOTICE Heart Rate Monitor is intended for general wellness purposes only. It is not a medical device and should not be used to diagnose, treat, or monitor any medical condition. Always consult a qualified healthcare professional for medical advice.
