Fitbit Revamps Weight Stats Page and Prepares 'Sleep Lab' with LLM Integration

Fitbit has redesigned the Weight stats page and logging experience in its app, making it consistent with other stats pages. The update includes a new "Day" tab and a carousel for viewing weight data. Additionally, Google is working on a new experimental feature called Sleep Lab which will analyze users' sleep patterns and behaviors using large language models (LLMs). This Sleep Lab feature will be initially tested on an opt-in basis before a wider launch, likely requiring Fitbit Premium subscription. It will involve a daily sleep journal to reflect and track progress with the aim of providing personalized suggestions for better sleep.
