Inspired in Dr.Maumi 'Speed+Avg.' this app shows the current and average heart rate in the same data field.

If configured in a full width field it can also display both average and maximum heart rate plus heart rate zones, percentage of fcmax and total time in HR zones (time in HR zone is not available on Edge 130 devices).

Highly customizable. You can use colors to highlight high/low heart rate values compared against the average heart rate +/- a configurable tolerance or highlight current HR value using colors according to the current HR zone.

Up/down arrow indicators can also be enabled to quickly and visually indicate if current heart rate is above or below the average heart rate +/- a configurable tolerance.

If using a half-width field you can configure if you want the datafield to display the value for average or maximum HR along the current value or even alternate both every 5 seconds. In this case average value will be displayed in blue and maximum in purple.

Lap support: when lap support option is enabled the average, maximum and time in zone values will be reset on every lap, or in workout mode when a workout step is completed, and you will visualize the current lap values.

Indicators:

[G]: indicates that heart rate zone thresholds information is retrieved from the device (requires permission to access user profile).
[S]: indicates that heart rate zone threshold calculation is done by the datafield based on a simple formula based on maximum HR.
[K]: indicates that heart rate zone  threshold calculation is done by the datafield based on Karvonen's formula instead of the simple one.
[A], [M] or [T] (half-width fields only): indicates if the displayed value along the current one corresponds to the average, the maximum or if the values are alternating every seconds in colors (avg = blue, max = purple).
[L]: indicates that lap information is displayed instead of activity totals.

Disclaimer: the datafield does not calculate heart rate on its own. A heart rate sensor compatible with your Garmin Edge device is required to measure heart rate values. Minimum Connect IQ version required 2.4.0.
