Fitbit is a line of wearable fitness devices owned by Google. Wearers of Fitbit products, including the Surge, Charge, and Versa, report the calorie counter function is inconsistent in reporting calories burned. Owners also state that Fitbit shows calories burned when idle. One owner reported nearly the same calories burned when they took 13,000 steps versus the next day 8,000 steps.
There is likely a case against Google for inaccurate advertising and/or defective products since the step-counter does not accurately report users’ steps. In January 2021 two related class-action lawsuits were filed against Fitbit for inaccurate heart rate monitoring, fraud, and violations of U.S. securities law.
