Also, would be nice if there was some control with the list of "Open Withs"

Edit: So I had class today, syncing it to my watch worked exactly as described, so yay. (JIC anybody else was curious)

So, this is a silly special case, I can't wear my watch during karate class, so I bought the HRM to sync with Garmin Connect, but it didn't seem to sync to the workout, I read online that it has to sync to the watch, so I just connected it to my watch, will this allow for recording my HR and then sync to Connect, or is there a special way to get it to sync with the workout?
