The company was founded in 2007 and gained popularity for its range of activity trackers, smartwatches, and related accessories. Fitbit’s products are designed to help individuals monitor and improve their health and fitness by tracking various metrics such as steps taken, distance traveled, calories burned, heart rate, sleep patterns, and more.

Fitbit offers a diverse lineup of devices to cater to different user preferences and needs. Some of the popular models include the Fitbit Charge, Fitbit Versa, and Fitbit Inspire. These devices incorporate features like GPS tracking, heart rate monitoring, smartphone notifications, music control, and exercise tracking.

What’s in this document

We get you started quickly creating a Fitbit® account and making sure your tracker can transfer the data it collects to your dashboard. The dashboard is where you’ll set goals, analyze historical data, identify trends, log food and water, keep up with friends, and much more. As soon as you’re done setting up your tracker, you’re ready to start moving.
Next, we explain how to find and use the features that interest you and adjust your preferences. To find more information, tips, and troubleshooting, please browse our comprehensive articles at help.fitbit.com.

Setting up your Fitbit Charge 2

For the best experience we recommend using the Fitbit apps for iOS, Android, or Windows 10. If you don’t have a mobile device, you can also use a Bluetooth®-enabled Windows 10 PC or Mac. For non-Bluetooth options visit help.fitbit.com.

Your Fitbit account asks for information such as height, weight, and gender to make various calculations such as stride lengths to estimate distance and basal metabolic rate to estimate calorie burn. You have the option to share your age, height, or weight with Fitbit friends but the information you provide is private by default.

Setting up your tracker on your mobile device

The free Fitbit app is compatible with more than 200 mobile devices that support iOS, Android, and Windows 10 operating systems.

To get started:

  1. Make sure the Fitbit app is compatible with your mobile device by checking http://www.fitbit.com/devices.
  2. Find the Fitbit app in one of these locations, depending on your device:
    • The Apple® App Store® for iOS devices such as an iPhone® or iPad®.
    • The Google Play™ Store for Android devices such as the Samsung® Galaxy® S5 and Motorola Droid Turbo.
    • The Microsoft® Windows Store for Windows 10 mobile devices such as the Lumia™ phone or Surface™ tablet.
  3. Install the app. Note that if you don’t have an account with the store you’ll be required to create one before you can download the app.
  4. When the app is installed, open it and tap Join Fitbit to be guided through a series of questions that help you create your Fitbit account, or login to your existing account.
  5. Continue following the onscreen instructions to connect, or pair, your Charge 2 to your mobile device. Pairing makes sure the tracker and mobile device can communicate with one another (sync data back and forth).

When you’re done pairing, read through the guide about your new tracker and then explore the Fitbit dashboard.

Setting up your tracker on your Windows 10 PC

If you don’t have a mobile device, you can set up and sync your tracker using a Bluetooth-enabled Windows 10 PC. The same Fitbit app that is available for Windows 10 mobile devices is available for your computer.

To get the Fitbit app for your computer:

  1. Click the Start button on your PC and open the Windows Store (called Store).
  2. Search for “Fitbit app” and when you find it click Free to download the app to your computer.
  3. If you’ve never downloaded an app to your computer you’ll be prompted to create an account with the Windows Store.Fitbit charger 2 Version 1 (2)
  4. Click Microsoft account to sign in with your existing Microsoft account. If you don’t already have an account with Microsoft, follow the onscreen instructions to create a new account.
  5. Open the app after it’s done downloading.
  6. Click Join Fitbit to be guided through a series of questions that help you create a Fitbit account, or login to your existing account.
  7. Continue following the onscreen instructions to connect, or pair, your Charge 2 with the Windows 10 app. Pairing makes sure the tracker and app can communicate with one another (sync data back and forth).

When you’re done pairing, read through the guide about your new tracker and then explore the Fitbit dashboard.

Setting up your tracker on your Mac

If you don’t have a compatible mobile device, you can set up your tracker with a Bluetooth-enabled Mac and use the fitbit.com dashboard to see your stats. To use this method you’ll first install a free software application called Fitbit Connect that lets Charge 2 sync its data with your fitbit.com dashboard.

To install Fitbit Connect and set up your tracker:

  1. Go to http://www.fitbit.com/setup.
  2. Scroll down and click the option to download. If the button does not correctly show your type of computer (for example, if it says “Download for Mac”), choose the correct type, then click the button.
  3. You’ll see an option to open or save a file; choose open. After several seconds you’ll see an option to install Fitbit Connect.
  4. Double-click Install Fitbit Connect.pkg. The Fitbit Connect installer opens.
  5. Click Continue to move through the installer.
  6. When prompted, choose Set up a New Fitbit Device.
  7. Follow the onscreen instructions to create a Fitbit account, or login to your existing account, and connect your tracker with Fitbit Connect.

When you’re done with the setup steps, Fitbit guides you through an introduction to your new Charge 2 and then takes you to the fitbit.com dashboard.

Syncing your tracker data to your Fitbit account

When you start using your Charge 2 you’ll need to regularly sync it with your Fitbit dashboard. The dashboard is where you’ll track progress, see your exercise history, track your sleep patterns, participate in challenges, and much more. We recommend syncing at least once a day.

The Fitbit apps and Fitbit Connect use Bluetooth Low Energy (BLE) technology to sync with your Fitbit tracker.

Each time you open the Fitbit app it syncs automatically if the paired tracker is nearby. You can also use the Sync Now option in the app at any time.
Fitbit Connect syncs every 15 minutes if the tracker is within 20 feet of the computer. To force a sync, click the Fitbit Connect icon located near the date and time on your computer and choose Sync Now.

Getting to know your Fitbit Charge 2

This section tells you how best to wear, navigate, and charge your tracker. If you bought an accessory wristband, you’ll also find instructions for taking off the original band and putting on a different one.

Wrist placement

Review these tips to make sure you’re wearing your tracker for optimal results.

All-day wear and exercise

For all-day wear when you’re not exercising, your Charge 2 should usually rest a finger’s width below your wrist bone and lay flat, as you would normally wear a watch.

For optimized heart rate tracking keep these tips in mind:

  1. Experiment with wearing the tracker higher on your wrist during exercise. Because blood flow in your arm increases the farther up you go, moving the tracker up a couple inches can improve the heart rate signal. Also, many exercises such as bike riding or weight lifting cause you to bend your wrist frequently, which is more likely to interfere with the heart rate signal if the tracker is lower on your wrist.Fitbit charger 2 Version 1 (4)
  2. Do not wear your tracker too tight; a tight band restricts blood flow, potentially affecting the heart rate signal. That being said, the tracker should also be slightly tighter (snug but not constricting) during exercise than during all-day wear.
  3. With high-intensity interval training or other activities where your wrist is moving vigorously and non-rhythmically, the movement may limit the sensor’s ability to provide a heart rate reading. Similarly, with exercises such as weight lifting or rowing, your wrist muscles may flex in such a way that the band tightens and loosens during exercise. If your tracker does not show a heart rate reading, try relaxing your wrist and staying still briefly (about 10 seconds), after which you should see a heart rate reading.

Fitbit Charge 2 General Info & Specifications


Your Charge 2 contains the following sensors:

  • A MEMS 3-axis accelerometer, which tracks your motion patterns
  • An altimeter, which tracks altitude changes
  • An optical heart rate tracker


The wristband that comes with Charge 2 is made of a flexible, durable elastomer material similar to that used in many sports watches. It does not contain latex. Accessory wristbands are available in genuine leather.

The buckle and frame on Charge 2 are made of surgical-grade stainless steel. While all stainless steel contains traces of nickel and can cause an allergic reaction in someone with nickel sensitivity, the amount of nickel in all Fitbit products meets the European Union’s stringent Nickel Directive.

Wireless technology

Charge 2 contains a Bluetooth 4.0 radio transceiver.

Haptic feedback

Charge 2 contains a vibration motor, for alarms, goals, notifications, and reminders.


Charge 2 contains a rechargeable lithium-polymer battery.


Charge 2 stores most minute-by-minute stats and exercise data for seven days. It stores SmartTrack data for three days and summary totals for 30 days. Heart rate data is stored at one-second intervals during exercise tracking and at five-second intervals at all other times.

Stored data consists of steps, distance, calories burned, floors, active minutes, heart rate, exercise, sleep, and stationary vs. active hours. Charge 2 can store a maximum of 10 hours of exercise data. This means that if you exercise for more than 10 hours and don’t sync your tracker, your exercise history will not include everything. We recommend syncing your tracker at least once a day.


The Charge 2 has an OLED tap display.


Wristband sizes are shown below. Note that accessory wristbands sold separately may vary slightly in size.
