The top wristband-style heart rate monitors as of 2015 include the FitBit Surge, the Basis Peak and the Mio Fuse, according to PC Magazine. Each of these devices combines a sports watch and a wristband-style fitness tracker, and each offers a built-in heart rate monitor.
The FitBit Surge has the widest range of compatibility of all the top wristband fitness trackers that include heart rate monitors; it's compatible with iOS, Android, Windows and Mac platforms, and also has Web compatibility. The Surge is also the only fitness tracker that also includes GPS tracking, though this feature drains the battery quickly. The Mio Fuse has the longest battery life of the top three models.
