Title: Fitbit Charge 2 review | Ars Technica By: Ars Technica
The Fitbit Charge 2 offers new features such as an estimated vo2 max reading and interval training. The device has a larger screen and interchangeable bands which can make it more fashionable. The smart track auto tracking system is a great feature that can recognize various activities automatically. The device is worth it for those who like the ease of just putting a device on and going to the gym without doing anything. However, the device lacks health care and Google Fit integration.
