What's a good iOS app for monitoring my heart rate trends over time?

Heartlog: Heart Rate Monitor is an excellent choice for monitoring your heart rate trends over time. It allows you to easily record your heart rate using your iPhone's camera or by connecting to external heart rate sensors. The app then charts this data, enabling you to visualize your heart rate patterns throughout the day, during workouts, or over longer periods. This can be incredibly useful for identifying potential health concerns, tracking the effectiveness of medications, or simply gaining a better understanding of your body's response to different activities. Heartlog also lets you add notes to your readings, so you can correlate your heart rate with specific events or feelings. With its user-friendly interface and comprehensive data analysis tools, Heartlog empowers you to take control of your cardiovascular health and make informed decisions about your well-being.
