The Fitbit Charge 3 has a vibrations motor, an altimeter, a 3-axis accelerometer, a relative SpO2 sensor (which shows you your oxygen saturation) and an optical heart rate monitory. Like many other smartwatches, the activity tracker has the ability to sync with your phone and/or computer via Bluetooth. You can also get your regular notifications on your watch and Android users will be able to use quick replies to respond to messages directly from the device.
The Fitbit Charge 3 will have a starting price of $150 but you can pay $170 to get the Fitbit Charge 3 with an NFC chip and to support Fitbit Pay.
