Fitbit s origins
Fitbitâs first device was the Fitbit Tracker in 2009, but 2013 brought wearables to the collective consciousness with the Flex (above).
These two devices brought the idea of step tracking and the evergreen 10,000 goal to the masses. But it was the next device, the Charge HR, that Conor Heneghan believes transformed the company thanks to its optical heart rate sensor.
âI certainly think the move to the optical heart rate tracking was pretty pivotal as a technical enabler, Heneghan told Wareable.
âWe build so much around that. The estimation of the sleep stages, sleep score, heart rate variability. It s all relying on that optical heart rate sensors, so that s a key milestone, he continued.
