Fitbit Cofounders Unveil Luffu, an AI Family Health App Now in Private Test

Park and Friedman pitch a family-first system that centralizes health data with user control over sharing.

Overview

  • Luffu is described by the company as an intelligent family care system intended to reduce the caregiving mental load by monitoring shared wellbeing across households.
  • The service is in private testing, and sign-ups are open on Luffu’s website for a limited public beta waitlist.
  • Its AI aggregates and organizes family health information from connected devices, Apple Health, Fitbit, medical portals, and user inputs such as voice, text, and photos.
  • The system proactively watches for changes to share insights and alerts, and it supports plain‑language health questions tailored to individual family members.
  • An app-first launch is planned to expand into complementary first‑party hardware, with the founders citing an estimated 63 million U.S. family caregivers as the market need.
