How we test Fitbit fitness and activity trackers
Our tough tests put each fitness watch or activity tracker through its paces. We check the accuracy of step, distance and heart-rate tracking in different scenarios. This ranges from a routine of daily tasks, such as loading or unloading the dishwasher and carrying the shopping, to more strenuous activities. This means we can tell you the fitness trackers that accurately measure your steps and those that don’t.
And we don’t stop there. We know a tracker will be useless if it’s so uncomfortable you’re reluctant to wear it, so we assess how comfortable each one is during exercise and for daily life.
