Lawsuit Claims Fitbit Heart Rate Monitor Is Inaccurate

CBS/January 8, 2016

SAN FRANCISCO (CBS) — The makers of Fitbit are being sued by people who allege that the popular fitness device isn’t accurately keeping track of their heart rate while exercising.

The lawsuit filed in federal court this week claims that the wrist-based activity tracker is consistently misrecording users’ heart rates by a “very significant margin.” It also takes aim at Fitbit commercials with slogans like “Every Beat Counts” and “Know Your Heart.”
