You can buy the Fitbit Charge 3 starting October 7

Fitbit is calling the Charge 3 its “smartest tracker yet” and its coming soon. The company’s latest fitness tracker will be coming to major retailers worldwide, online, and at Fitbit.com starting October 7^th. Here the Charge 3 will cost $199.95 for the Black/Graphite Aluminum or Blue Gray/Rose Gold Aluminum models and $219.95 for the Lavender Woven/Rose Gold Aluminum or Frost White/Graphite Aluminum models.

This tracker features a swim-proof design and has a large touchscreen display. Aside from the company’s usual slew of sensors that helps track your health and fitness activities, Fitbit is bringing its relative SpO2 sensor to its tracker form factor for the first time with the Charge 3. The data it gets from this sensor will be fed to the upcoming launch of its Fitbit Labs Sleep Score beta, which lets you better understand sleep-related metrics such as sleep quality and breathing disturbances. This beta program is coming first to the US, Australia, and the UK this November. And when they get FDA approval, this data can even be used to screen and detect more serious health conditions like sleep apnea.
