The Fitbit Sense 2 and Versa 4 are two of the most popular devices from Fitbit. They look fairly similar - but work quite differently - so you might be stuck choosing between them if you want to upgrade your fitness tracker in 2025.
As a health editor at woman&home and a fan of the best Fitbits, I've tried and tested every device on sale over the years. They are among the best fitness trackers overall, balancing premium lifestyle features and excellent health monitoring at a reasonable price point.
