When searching for smartwatches compatible with the Fitbit app, the options are limited.
Only Fitbit devices and Google Pixel Watches work directly with the Fitbit app.
Third-party smartwatches from other manufacturers cannot sync data directly to the Fitbit ecosystem due to proprietary technology restrictions.
This limitation exists because Fitbit uses proprietary algorithms and data processing methods that aren’t shared with other manufacturers.
The integration between hardware and software is designed specifically for Fitbit’s own devices and their Google partnership products.
This comprehensive guide will explain the current state of Fitbit compatibility and present the best alternatives for health-focused smartwatch users.
Let’s get started.

What’s the right choice for you?
If you’ve already invested in Fitbit, prefer Fitbit’s approach to health insights and motivation, want seamless data synchronization, and value Fitbit premium features and community, you should go with Fitbit compatible devices.
However, if you prioritize smartwatch features over fitness tracking, are already using another health platform, or need specific features not available in Fitbit devices, alternative options would do.
The Future of Fitbit Compatibility
Google’s acquisition of Fitbit has led to significant changes in the platform.
Third-party app support has been discontinued and Google is focusing on integrating Fitbit functionality into its own ecosystem rather than expanding compatibility with other manufacturers.
This means that true Fitbit app compatibility will remain limited to Google and Fitbit devices, making the Pixel Watch series the primary gateway for non-traditional Fitbit users.
