LED jump rope hooks up to a smartphone, shows data in thin air

People can’t count? This seems sort of silly — a large part of the appeal of jumping rope is that it’s so simple a caveman can do it

I’m amazingly bad at keeping count when exercising. Either I’m counting and bored or letting my mind wander and solving other problems and have no clue where I was at.

So yeah. I’d fit that ‘can’t count’ use case.
