The latest semi-smart watch from outdoor tech specialist Garmin sees it add a much wanted feature to the spec sheet of the Forerunner 225 tracker -- the ability to count how hard that flight of stairs made your heart beat via its own embedded wrist sensors.
So no more pairing it with an external sensor to track the erratic thumping in your chest, thanks to a built-in optical system that pings your flesh to track the minute changes caused by the red stuff. The Forerunner 225 boasts a four week battery life when used without GPS in simple activity tracking mode, sinking to seven hours of full-on GPS/heart action when everything's turned on. It's £239.99 and available in June. [Garmin]
