The Fitbit Versa 4 Blue is a digital touchscreen smartwatch designed for everyday wear and multi-sport tracking. It features built-in GPS for outdoor pace and distance, Bluetooth connectivity for phone pairing, and a lightweight aluminium case in a platinum finish with a blue S/L size band. The device is waterproof to 50 m and runs Fitbit OS, offering a combination of activity tracking, sleep analysis and health metrics including heart rate variability to support informed training choices.

Advantages

The watch provides an integrated Daily Readiness Score that analyses recent activity, sleep and heart rate variability to suggest whether to push for an intense workout or opt for recovery.
