Last updated: 23 March 2018

Fitness trackers and smartwatches make it possible to learn about your activity, sleep or eating habits with nothing but a swift glance at a smartphone or your wrist.

Our test covers fitness bands and smartwatches that work with iOS and Android smartphones. Our expert testers give each tracker and watch a thorough workout to help you find the models that:

  • are the most accurate for fitness tracking
  • help you to keep track of your heart rate, food intake and burned calories
  • are water-resistant and have GPS.

Our Recommended list will help you quickly see which models come out on top.

Some models in our test include a heart rate monitor. We tested these against an ECG machine at the Faculty of Health Sciences at the University of Sydney and found that accuracy was mixed. See the summary of our findings.

Most of the products on test have fitness as the main design focus. However smartwatches also deliver much of the functionality of a fitness tracker with additional features and functions such as live notifications, the ability to accept a mobile call and support for third party apps.

Ease of use score

We set up each fitness tracker on Android, iOS and Windows where available and score how easy they are to set up and wear, and how well they track information via the band and via the related app.

Comfort score

Expand to view more details.

A panel of six people (3 men and 3 women) try on each fitness tracker. They rate how easy it is to put on and take off the band, how easy it is to adjust to get the best fit, and how comfortable the band is to use and wear daily. The scores are then averaged.

Pedometer accuracy score

The pedometer will measure your steps, though accuracy will vary depending on what you put in as your height, weight and, in some cases, pace length, and the technology used in the development of the device.

Digital clock

Most trackers can eliminate the need for a standalone watch as they present the time on your wrist. Polar M600 and TomTom Adventurer display time to the nearest 5 minutes. Misfit Shine and Jawbone Move double as analogue clocks to the nearest five minutes. Sony Smartband 2 SWR12 displays time using LED lights (no numbers).

Built-in GPS. Some models also include GLONASS (the Russian version of GPS). Models that support GPS and GLONASS should deliver the fastest position identification.

Heart rate monitors are a useful barometer of effort for some people and can act as a way to measure your fitness regime more precisely. Garmin Forerunner 235 provides instantaneous readings only.

While fitness tracking is the main purpose for these devices, notification of a text or phone call coming in from your smartphone can be very handy.
