Pulsometer widget for the Sensor Watch. This is to some extent pretty basic: you use a finger to count 30 pulses on the wrist; then there’s a lookup table that converts that amount of time to a heart rate. Turns out an index finger is a pretty good sensor! https://github.com/joeycastillo/Sensor-Watch/commit/0f349cb52e7436303f61a3dd2dde2f40d3dc05c3
