Fitbit has announced its first smartwatch, the Ionic. A health and fitness platform, Ionic offers a personalized experience. Ionic builds on Fitbit's health and fitness expertise with a new relative SpO2 sensor, making it possible to track deeper health insights like sleep apnea in the future, GPS tracking, on-device dynamic workouts, improved heart rate tracking, and water resistance up to 50 meters.

Smart features like contactless payments, on-board music, smart notifications, and a variety of popular apps and clock faces are available in the Fitbit App Gallery. Ionic offers more than four days of battery life, automatic activity and sleep tracking, and cross-platform compatibility, according to the vendor. Ionic is available for pre-sale starting August 28 on Fitbit.com and in retailers globally starting October 2017, with a new Fitbit Ionic adidas special edition device coming in 2018. The Fitbit app software development kit (SDK) will be open to developers in September 2017, the company said.
