the contenders

Fitbit Charge 2

You don’t need a degree in biometrics to understand the awesome data captured by Fitbit’s Highly Commended do-it-all tracker with automatic activity tracking. You can use it to easily keep tabs on sleep patterns, steps taken and calories burned, and to measure your heart rate or set health targets.

Polar A370

The water-resistant A370 is your ticket to a healthier lifestyle. Accurate wrist-based heart rate monitoring keeps an eye on heart health, while Smart Coaching guides you through workouts and sets goals to help you reach peak fitness. At night, Sleep Plus tracks shuteye, providing feedback on how to optimise your time in bed.

TomTom Spark 3 Cardio

The waterproof Spark 3 Cardio, complete with built-in heart rate monitoring, is the ideal tracker for runners. Integrated GPS keeps you updated with distance, speed, pace and route stats in real-time, while Race Mode pits you against yourself – select a past workout and see if you can smash your last performance!

Nokia Steel HR

It may look more like your average analogue timepiece than a techy wearable, but Nokia’s understated activity tracker has bags of smarts. The Steel HR automatically knows when you start a run, bike ride or swim, and tracks everything from steps to heart rate – all while looking like a fine fashion piece.

Moov HR

The next logical step for Moov was to add heart-rate monitoring to its minimalist fitness tracker system. As before, the Moov app’s voice coach guides you through workouts, but this time it uses your heart rate data to optimise each session, maximise results and help you turn annoying, unwanted flab into muscle.
