Fitness bands are focused on the specific tasks associated with fitness (steps, sleep, tracking heart rate etc) while smartwatches also include additional productivity and communication features.

Recommended View more details.

We recommend models with a CHOICE Expert Rating above 80%.

CHOICE Expert Rating View more details.

This overall score consists of: ease of use (30%), comfort (35%), pedometer accuracy (17.5%) and distance accuracy (17.5%).

Ease of use score View more details.

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 View more details.

We use a panel of six people (3 men and 3 women) and get them to 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.

Step count accuracy score View more details.

We measure how accurately each fitness tracker measures steps. Accuracy depends on what you put in as your height, weight and, in some cases, pace length, and the technology used by the fitness tracker.

Distance accuracy score View more details.

We measure accuracy of distance and how well it tracks how you move. The fitness tracker uses a number of technologies to track how far you've travelled. Accuracy depends on what you put in as your height, weight and, in some cases, pace length.

Resting heart rate accuracy View more details.

We measure five different people tried on each fitness tracker and readings are taken against a medical-grade monitor. Each tracker is given time to stabilise. Note, we no longer test resting heart rate accuracy as of 2022.

Active heart rate accuracy View more details.

We measure accuracy and how well each tracker responds to changes in heart rate, and how it deals with adverse conditions, such as sweat and motion. Note, we no longer test active heart rate accuracy as of 2022.

Year tested View more details.

Models tested in, and after, 2022 are no longer assessed for resting and active heart rate.

Waterproof or resistant claims View more details.

There are a variety of certifications that indicate the degree of dirt, grime, grit and water protection these include ATM (Atmospheric Pressure), IP (ingress protection) and WR (water resistant). The rule of thumb is, the higher the number, the greater the protection. For example, 1 ATM is equivalent to 10 metres underwater and 5 ATM is equivalent to 50 metres. Some manufacturers may make broad claims instead such as "water resistant."

Bluetooth View more details.

Bluetooth 5 is the most recent, widespread version which improved battery life as well as speed, signal strength and performance over longer distances. But fitness bands and fitness features on smartwatches don't really require features beyond the slightly older Bluetooth 4.0. "Smart" Bluetooth is more or less the same as 4.0. Some brands do not specify the version used.

Yes
Session tracker View more details.
