Smartwatch or fitness tracker?

In this test, the Samsung Gear S2 was assessed as a fitness tracker rather than as a smartwatch. Our smartwatches test can be found here.

How we test

Overall score includes:

Ease of use (30%): We test each fitness tracker on Android, iOS and Windows where available and score how easy it is to set up and wear, and to track on-the-go information via the band and its interfaces.

Comfort (35%): A panel of ten, split between five men and five women, try on each fitness tracker and assign them scores based on how easy they are to put on, adjust and wear. The trackers in the test are medium-sized, where applicable.

Pedometer accuracy (17.5%) and distance accuracy (17.5%): We measure paces and distance with a calibrated tracking tool, and then measure this against what the fitness tracker displays.

We also perform two tests on the heart monitors:

Resting heart rate: We measure the resting heart rate of five people using each of the fitness trackers and a medical grade heart monitor, the GE Healthcare Carescape V100. A score is then calculated based on the fitness tracker's accuracy.

Active heart rate: Athletes at the Sports Chamber at Sydney University exercise on a treadmill wearing one of the fitness trackers. A 12-lead ECG provides a real time reading of their heart rate, which is then compared to the readings of the fitness tracker. Readings of both are taken at 10 second intervals in the first minute, one minute intervals for five minutes, and then at 10 second intervals during the last minute of cooling down.
