Lebanese startup Instabeat put its heart rate and activity tracker on the head, not because it reads brain waves, but because competitive swimmers didn't want to wear anything on their bodies that might create drag. The head is safe though, as that's where many swimmers would wear goggles anyway. Instabeat was designed to fit into an existing pair of goggles and create minimal resistance. As an added bonus, the device is able to use colored lights to convey to swimmers whether they're in their target heart rate on the go via a heads up display. The company raised $56,000 on Indiegogo this year and plans to ship its first units in November.
