Key Takeaways
1. Introduction of New Sleep Metrics: The upcoming Fitbit app update will include new sleep metrics, such as Sleep Need, which provides a detailed breakdown of individual sleep requirements.
2. Understanding Sleep Debt: Another new metric, Sleep Debt, will help users assess their energy levels based on sleep history, indicating if they need to rest more.
3. Changes in Tab Organization: The app may revert to a tab structure that includes dedicated Fitness and Sleep tabs, moving away from the current three-tab layout.
4. Beta Testing of Features: Both new sleep metrics were previously tested in the Fitbit Personalized Sleep Schedule Lab, indicating readiness for wider release.
5. Uncertain Release Timeline: The release date for the updated app version remains unknown, with the current version only mentioning bug fixes and performance improvements.
A significant update seems to be coming soon for the Fitbit application. Recently, two new sleep metrics and a revamp of the tab organization were found in the code of the Fitbit app version 4.60, which was released in early January 2026.
New Sleep Metrics
According to Gadgets and Wearables, users of Fitbit devices may soon have access to extra sleep metrics in an upcoming update. For instance, owners of devices like the Fitbit Charge 6 (curr. $99.95 at Amazon) can already monitor their sleep duration, stages, and schedule, along with a calculated Sleep score. It appears that a new feature called Sleep Need is being developed. Lines in the app’s code suggest that this metric will provide “a detailed breakdown to explain how your sleep need was calculated”.
Understanding Sleep Debt
Another new sleep metric is Sleep Debt. The code for the Fitbit app includes phrases such as “Less than usual may mean you’ve built up some ‘sleep debt’, and you may want to take it easy”. This indicates that this score will help users understand their current energy levels based on their sleep history. Both of these features were beta tested in the Fitbit Personalized Sleep Schedule Lab last year.
Potential Tab Structure Changes
In addition to these metrics, the app’s tab structure may be getting an update. Right now, the app consists of three tabs: Today, Coach, and You. This layout was introduced in an August 2023 redesign. According to another report from Gadgets and Wearables, the app’s code shows signs that dedicated Fitness and Sleep tabs could be brought back. Just to remind you, before the 2023 update, there were four tabs: Today, Fitness, Sleep, and Health. How these tabs will be organized in the future remains uncertain. Additional clues pointing to a design change include onboarding messages like “Ready to explore your new redesigned app?”.
It’s still unknown when Fitbit will release this new version of its app for iOS and Android users. The change log for version 4.60 on both platforms simply mentioned that it included “bug fixes and performance improvements”.
