Is Force accurate?
Fitbit is dedicated to developing the most accurate wrist-based activity trackers on the market. Our team has spent more than a year and performed multiple internal studies to rigorously test the accuracy of Force. Through our testing, we have confirmed that Force is one of the most accurate wireless tracking devices designed specifically for your wrist.
Why is my Force step count different than my count on other Fitbit products?
Force has been tested extensively against our clip-based devices like the Fitbit One and Fitbit Zip. That said, because Force is specifically designed for your wrist, if you move your body a lot and not your arms (or vice versa), you may get a slight difference in activity than you would see on your clip-based trackers. Additionally, since you’re more likely to wear Force 24/7, you may count a few more steps.
This is no different than any wrist-based tracker on the market. For most people, there may be no difference at all between clip and wrist based trackers or it may be within a few percentage points difference. That said, if you have a lifestyle where you move your hands a lot such as playing the drums everyday, you may see a few extra steps on your Force because we do want to give you credit for this activity.
Why do I get extra steps sometimes?
Force is a motion sensor on your wrist. There are many instances where your hands may be moving, but your body may not be, such as playing the drums, cooking, or even burping a baby. Force may count some extra steps here and there to give you credit when it thinks you are active. For more information, see How does my tracker count steps?
Don’t forget, it’s the trends that matter the most in achieving your health and fitness goals.
Why do I get extra floors sometimes?Your Force detects floors using an altimeter, which is a sensor that calculates altitude based on atmospheric pressure. Though your Force is designed to look for pressure changes based on elevation gains, occasionally pressure changes caused by, for example, a gust of wind, a weather change, or opening a door can cause your Force to register an extra floor or two. For more information, see How does my tracker count floors?
As with extra steps, trends matter most when assessing your activity level.
Will Force count steps when I’m pushing a stroller or a shopping cart?
Force will count your steps when you are pushing a stroller or a shopping cart because we do want to give you credit for this activity. That said, because your hands are not moving, your step count may be a bit lower during this activity.
Will my Force pick up steps when I’m in the car or riding a vehicle somewhere?
Force is a smart device that has been designed not to pick up your steps in these activities. It has been tested against driving, buses, trains, and other public transportation and should not give you extra steps when you’re traveling. That said, sometimes you’ll hit a bumpy road and may get a step or two. These should not make a big difference in your overall stats.
Will Force count steps when I’m working at a desk?
Force has been tested against activities like typing, writing, and using your computer. Generally, Force will not pick up steps when you’re working at your desk. If it does pick up a few, these should not make a big difference in your overall stats. If you wear Force on your dominant hand (e.g., the hand you write with), we recommend that you double check your device settings (see below).
How can I make my Force tracking more accurate?
You can improve the accuracy of your Force by changing the Dominant Hand setting on your Device Settings page (http://www.fitbit.com/settings/device), which can be found under the gear icon in the upper right corner of your Dashboard. Changing this setting to "Dominant" will decrease sensitivity of step counting and should reduce over counting of steps when your body is not moving. Using the "Non Dominant" setting will increase the sensitivity of step counting, and can be used if your Force is not counting enough steps. You can also add other personal settings such as stride length on your settings page to make Force more personalized for you.
