Heart Matter

Features
Read full description

Tracks real-time heart rate with most BLE chest strap heart rate sensors. Some smartwatches and wrist-worn devices may not connect because they do not support the standard BLE Heart Rate profile. Whether you’re aiming for fitness or endurance, effective aerobic exercise means keeping your heart rate at 60–80% of your maximum for at least 15 minutes. Simply set your age, and the app automatically calculates your maximum heart rate and key target zones (60%, 70%, 80%), then shows them on a real-time graph—helping you avoid slowing down or pushing too hard, for safer, more effective workouts. When you press the PiP button, a small window appears. The color on the left side of the window indicates system status: green means normal, red indicates overheating, and gray shows delay. The blinking dot next to the number confirms that heart rate is being measured and updated continuously. The background color of the number on the right side represents heart rate zones: below 60% of maximum is blue, up to 80% is green, up to 90% is orange, and above 90% is red. Features: • Real-time heart rate and RR interval tracking with most BLE chest-strap monitors (smartwatches and wrist devices not supported) • Continuous background heart rate collection—even with the screen off • Automatic reconnection to your last paired device, with alerts if the connection drops • Full connection event logging for reliable monitoring • Customizable high heart rate alerts • Seamless data sync with Apple Health
