* Group related sessions by adding your own notes, then searching for sessions matching those notes * Maximise the screen area for graphs on iPhone and iPod touch using landscape orientation * Integration with Apple Health: import existing workout data and store new workouts * Review all your sessions offline to spot trends in your data * Support for both Bluetooth sensors and Apple Watch * Display a real-time graph of heart rate against time on your iPhone or iPad The key FREE features of Heart Graph include: (Note some features require a one-off In-App Purchase, as described below.) Data from previous sessions can then be compared to give a deeper understanding of how your body is changing over time, for example by directly comparing the graphs for equivalent sessions, viewing statistics such as max, mean and resting heart rate across sessions, or seeing the proportion of time spent in different heart rate zones aggregated over weeks or months.

Heart Graph allows you to record new data and see your heart rate graph in real time, as well as importing existing data from Apple Health. Heart Graph can be used for all types of aerobic exercise including running, cycling, rowing or gym work, and of course you can also use it to study your normal heart rate for general health reasons. Knowing your current heart rate is useful, but seeing in real time how it varies over a longer period gives you much more information, especially when trying to understand how your body is responding to a training plan.
