HeartFan 4+

Control your homekit devices during a workout.
HeartFan allows you to control your fans and lights within your house based on your heart rate. This can be especially useful for indoor sports where you want your fan to go up when you start sweating. Also controlling the light when reaching your limits gives you an immersive extra motivation.
