How to Troubleshoot and Resolve Fitbit App Crashing Issues
When the Fitbit app starts crashing, it hinders your ability to manage Fitbit devices and access the app’s features. This problem has been reported across all Fitbit-supported platforms. Sometimes, an app update or an OS update might trigger the issue. Additionally, the app may not crash upon launch, but instead when accessing specific features, such as viewing charts.
In certain situations, you may encounter a black screen without an error message. At other times, incessant crash popups may bombard the screen—even with the app running in the background—severely disrupting regular phone use.
Troubleshooting Prerequisites
- Compatibility: Ensure that your device is compatible with the Fitbit app. Check the compatible device list on the official Fitbit website.
- Server Status: Verify any service outage by checking online services like DownDetector or official Fitbit social media channels.
- Storage Space: There should be sufficient free storage space on your device. A lack of space can cause the Fitbit app to crash during syncing or other operations.
- Relaunch the Fitbit app.
- Restart your device.
- Relog into the Fitbit app.
1. Update the Fitbit App and Your Device’s OS
An outdated Fitbit app or a device’s OS missing the latest patches can result in incompatibility, leading to crashes. Updating both to the latest versions can solve the problem.
Update the Fitbit App
- Open the Google Play Store or Apple App Store and search for Fitbit.
- If an update is available, select it to begin the update process.
Update the Fitbit App - After updating, restart your device and open the Fitbit app to check for proper functionality.

If you have exhausted all the methods above and the Fitbit app still crashes, it would be wise to reach out to Fitbit support for further assistance.
Here are a few additional methods you might consider if the Fitbit app continues to crash:
11. Check for External Factors Affecting Connectivity
Outside interference from other Bluetooth devices or Wi-Fi networks may sometimes cause the Fitbit app to malfunction. Consider the following steps:
