Fitbit is expanding its personal health coach with three major updates aimed at making wellness tracking more comprehensive. The new features include Cycle Health for women's period and cycle insights, a Resilience score to measure stress impact, and enhanced nutrition tracking with personalized macronutrient ranges. These updates are designed to help users better understand their health patterns and make informed decisions.

In a significant move, Fitbit is opening its Public Preview to non-Premium subscribers, breaking from its previous model where these features were exclusive to paying users. The company says this expansion allows more people to access advanced health insights without requiring a subscription. The Resilience score specifically focuses on mental health by tracking how stress affects the body, incorporating mindfulness session tracking and mood logging.

The updates arrive as Fitbit continues to evolve its AI-driven health platform, which recently added the ability to integrate medical records for more personalized responses. While some users may be hesitant to share medical data with an AI, Fitbit emphasizes this feature is optional. The company has also expanded availability of its health coach to users in the U.K., Canada, Australia, New Zealand, and Singapore, demonstrating its commitment to global accessibility.
