About this app
See your live heart rate, straight from your Bluetooth sensor. Heart Rate BLE connects to any standard Bluetooth LE heart-rate sensor — chest straps, armbands, or a sports watch broadcasting heart rate (such as Garmin's Broadcast Heart Rate mode) — and shows your pulse in real time. LIVE HEART RATE • Big, readable beats-per-minute display with a heart that pulses at your actual heart rate • Signal awareness at a glance: know immediately when the sensor stops broadcasting or loses contact • Automatic reconnection when the link drops LIVE ACTIVITY & WIDGET • Follow your heart rate from the Lock Screen and Dynamic Island with Live Activities • Add a home-screen widget to keep your latest reading in view SIMPLE BY DESIGN • No account, no ads, no tracking — your heart rate never leaves your device • Works with the standard Bluetooth Heart Rate profile (GATT Heart Rate Service) • Built-in demo mode: explore the whole app with virtual sensors before pairing real hardware Pair it with a chest strap for the workout, or with your watch's broadcast mode to see your pulse on a bigger screen.
