Optical heart rate when not moving is pretty easy to do.
Measurements are much harder when the user is moving around erratically, such as is typical with exercising.

For anything optical, you need accelerometers and lots of fun algorithms to compensate for motion. Soon as the motion is something the algo wasn't trained on, everything falls apart.
