The Fitbit app on Android is being updated to version 4.66, which includes new features such as food and mood logging capabilities. The update is being rolled out in stages, and many users, including those with the Google Pixel 10 Pro, may not have immediate access. Food logging has been revamped and can be accessed via the Gemini coach button for public preview users, while standard users can still log meals using the “+” button. The update also enhances hydration tracking, allowing users to log water under the label “log water.” The navigation bar has been redesigned, replacing the Coach and You tabs with Fitness, Sleep, and Health tabs. The Health tab now includes new Focus Areas like Nutrition and Mental Wellbeing. The rollout is expected to continue over the coming days.
