Devices like the Garmin Vivosport and the Samsung Gear Fit2 Pro offer similar features and accuracy levels. However, the choice between these devices often comes down to personal preference, budget, and specific needs such as GPS tracking or smartwatch functionalities.
Factors Influencing Accuracy
Several factors can influence the accuracy of the Fitbit Flex 2, including:
– Wear and Tear: The condition of the device and its strap can affect how well it tracks activities.
– User Input: Accurate information about the user, such as weight and stride length, is crucial for precise tracking.
– Activity Type: Different activities have varying levels of tracking accuracy, with walking and running generally being more accurately tracked than cycling or swimming.
Tips for Improving Accuracy
To get the most accurate data from the Fitbit Flex 2, users can follow a few simple tips:
– Wear the Device Correctly: Ensure the device is snug but not too tight on the wrist.
– Calibrate the Device: Especially for features like stride length to improve distance tracking accuracy.
