The latest Fitbit devices require an iPhone or Android phone. To verify that your phone is compatible with the Fitbit app, visit fitbit/devices.
If your phone or tablet isn’t compatible, you can set up some Fitbit devices on a Mac or Windows 8.1 computer with a program called Fitbit Connect.

Note: If you’re setting up certain Fitbit devices with an Android phone, a notification appears on your phone to begin the setup process. Tap the notification and follow the on-screen instructions to set up your device. If you don’t have the Fitbit app, the notification takes you to the Google Play Store to download the app.
- Apple devices—Apple App Store
- Android devices—Google Play Store
- Windows 10 devices (phones, tablets, and computers)—Microsoft Store
- Open the Fitbit app and tap Join Fitbit.
- Follow the on-screen instructions to create a Fitbit account and connect (“pair”) your Fitbit device to your phone or tablet. Pairing makes sure your Fitbit device and phone or tablet can communicate with one another (sync their data).
Note that to create a Fitbit account, you’re prompted to enter your birthdate, height, weight, and sex to calculate your stride length and to estimate distance, basal metabolic rate, and calorie burn. For more information, see How does my Fitbit device calculate my daily activity? After you set up your account, your first name, last initial, and profile picture are visible to all other Fitbit users. You have the option to share other information, but most of the information you provide to create an account is private by default.
For Fitbit Ionic, Fitbit Sense, Fitbit Versa, Fitbit Versa 2, and Fitbit Versa 3, you’re prompted to connect your watch to your Wi-Fi network. These devices use Wi-Fi to set up your watch, download playlists, download apps from the Fitbit Gallery, and for faster firmware and Fitbit OS updates. For best results, connect your watch to your home Wi-Fi network. For more information, see How do I connect my Fitbit watch to Wi-Fi?
For Charge 5, your phone might share your location with your tracker to reduce the time it takes for the built-in GPS sensors to connect to GPS satellites for the first time. Make sure the location permission for the Fitbit app is allowed. For instructions, see the Apple help article or the Google (Android) help article.
If you don’t have a compatible phone or tablet, you can set up and sync most Fitbit devices on your computer with Fitbit Connect. Fitbit Connect is a free software application that lets your Fitbit device sync its data with your fitbit dashboard.
If your computer isn’t Bluetooth-enabled, you must use a wireless sync dongle to set up and sync your Fitbit device. Most Fitbit devices don’t come with a dongle, but you can buy one from the Fitbit Store. We recommend using the Fitbit app if you can.
