Overview

• Google will launch an opt-in preview of a Gemini-powered personal health coach in October for U.S. Fitbit Premium members across Pixel Watch and Fitbit hardware.
• The coach builds personalized weekly training and recovery plans that adapt in real time to device metrics and user check-ins about illness or injuries.
• New sleep algorithms analyze weekly and long-term patterns and propose adaptive schedules to improve rest, recovery, and jet lag management.
• A redesigned Fitbit app centers the coach with an Ask Coach prompt, clearer metric visualization, improved syncing, and a new dark mode.
• The system ingests data from Fitbit and Pixel Watches plus third-party sources via Health Connect and HealthKit, while reviewers caution about LLM reliability and data privacy.
