Fitbit Founders Return with AI Family Health App

Fitbit co-founders James Park and Eric Friedman have launched Luffu, a new app built around AI that pulls together a family’s health data and keeps a running watch for changes. The company says the system can spot trends across records, wearables, notes, and uploads, then flag potential issues and surface follow-up questions for a caregiver. It also works like a chat assistant, answering health-related prompts in everyday language while drawing from the household’s stored information. Luffu supports kids, adults, aging parents, and even pets, aiming at the person who manages appointments, medications, and paperwork. Users can add details with voice, text, or photos, and the app connects with Apple Health and Fitbit. Access starts via a waitlist.
