Although the Ionic is mainly an exercise tracker, it does have some other useful features.

For instance, you can store and listen to music while you exercise, and a partnership with Pandora will allow Pandora Premium and Plus subscribers to take Pandora stations offline to the device. The company also introduced a new Bluetooth wireless headset, the Fitbit Flyer, that can be purchased separately.

A near-field communications chip embedded in the device lets Ionic users make purchases at retailers equipped with NFC checkout points. Fitbit has partnerships with AmEx, MasterCard and Visa. Fitbit Pay incorporates technology from Coin, which the company acquired last year.
