Heart Rate

Shows the wearer's live heart rate, read straight from the watch's sensor.

Settings

Row	What it does
style	Text, or a Ring, Bar or Circle gauge.
min bpm	For gauges: the heart rate that reads as empty. 40 is a typical resting floor.
max bpm	For gauges: the heart rate that reads as full. 180 is a common exercise ceiling.
show bpm text	Off draws nothing, reserving the box for your own heart icon or graphic.
unit on own line	Puts "bpm" on its own line under the number, for narrow boxes.
font / font size	Typeface and size. Size 0 means automatic.
h. align / v. align	Where the reading sits in its box.
colour	The colour of the text or gauge.

For the Ring, Bar and Circle styles, the gauge shape rows (shape, blips, gap, taper, track colour) work like they do on Progress Arc.

Test it with the heart rate row in the Simulate tab. On a real watch, heart rate updates on the watch's own schedule and may read blank until the sensor has a value.

Every object also has the shared rows (position and size, ambient look, show when, Color Style and more), explained once in Settings Every Object Shares.
