PulseCheck: Heart Rate Pulse

PulseCheck measures your heart rate using your iPhone's rear camera and flash (PPG). No sign-up, no smartwatch, no chest strap. Runs on your device.

PulseCheck is a 100% free iPhone app that measures your heart rate using the rear camera and flash: place a fingertip over the lens, hold still for a few seconds, and it returns your pulse in BPM. It uses photoplethysmography (PPG) and on-device signal processing, with no smartwatch, no chest strap, no sign-up, no account, and no paywall. Your readings are saved locally on your iPhone and, if you choose, can sync to Apple Health.

A calm pulse check, on your phone.

WHAT MAKES PULSECHECK DIFFERENT

• 100% free. No subscription. No "unlock to see your reading" paywall. Ever. • No sign-up. No email. No account. • No smartwatch needed. The rear camera and flash are the sensor. • Works after a workout. Post-Workout Mode loosens motion rejection so you can measure right after a run. • Calm framing. We never show "abnormal" or panic colors. Your reading is just a reading.

HOW IT WORKS

PulseCheck uses photoplethysmography (PPG). The camera and flash detect tiny color changes in your fingertip caused by your pulse, and on-device signal processing turns that into a BPM number with a clear confidence label.

ON-DEVICE & PRIVATE

Your pulse readings are saved locally on your iPhone (in SwiftData), and if you want, you can optionally sync them to Apple Health — that toggle is off by default. PulseCheck shows ads to stay free; like most free apps it may ask for tracking permission, which you control in Settings.

LIQUID GLASS UI (iOS 26)

Built natively for iOS 26 with the new Liquid Glass design language. Warm coral gradients, a frosted "lens" that morphs through your measurement, SF Pro Rounded for the BPM digit. Designed to feel like a wellness tool, not a clinical device.
