The Claim
Wristband activity trackers and smartphone applications produce step count measurements that are moderately to strongly correlated with those from pedometers in sedentary white-collar workers, but the absolute values differ, indicating device-specific measurement bias.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Wristband trackers and smartphone apps give step counts that match pedometers in pattern but not in exact numbers when used by sedentary white-collar workers, showing each device measures steps differently.
See the scientific wording
Wristband activity trackers and smartphone applications yield moderately to strongly correlated step counts compared to pedometers in sedentary white-collar workers, but the absolute values differ, indicating device-specific measurement bias.
Wristbands and phones detect arm and body movements differently than pedometers, which only count steps when the hip moves in a specific up-and-down pattern. This causes each device to count the same walking differently because they sense motion in different places and use different rules to decide what counts as a step.
What the research says
1 studyDifferent fitness trackers (wristbands, phones, pedometers) count steps differently, even when worn at the same time — so you can’t just compare their numbers directly. The study found that while they all show similar trends, the actual step counts don’t match up.
