Fitbit Founders Launch AI App to Help Family Caregivers

Caring for aging parents or sick family members just got a powerful new ally, thanks to the minds that revolutionized personal fitness tracking.

James Park and Eric Friedman, who created Fitbit, launched Luffu this week after experiencing firsthand how overwhelming family caregiving can be. Park spent years coordinating his mother's health care from across the country, struggling with language barriers and scattered medical records. He realized the tools that work for tracking our own health fall short when caring for others.

The timing couldn't be better. Nearly one in four U.S. adults now serves as a family caregiver, a 45% jump from just a decade ago. These caregivers juggle information spread across doctor portals, pill bottles, calendars, and handwritten notes while trying not to make their loved ones feel smothered.

Luffu uses AI to bring order to the chaos. Families can log health information for everyone under one roof using voice notes, text, or photos of prescriptions and test results. The system learns normal patterns for each family member and flags concerning changes, like unusual blood pressure readings or disrupted sleep.

The platform answers questions in plain English too. Users can ask "Is Dad's new meal plan affecting his blood pressure?" or "Did someone give the dog his medication?" No medical jargon or complicated interfaces required.

The Ripple Effect

What makes Luffu different is its recognition that health care happens in families, not vacuums. A child's allergy might affect meal planning for everyone. A parent's medication schedule impacts the whole household's routine. By treating family wellness as interconnected rather than individual, the platform reflects how people actually live.

The app launches first, with hardware devices planned for later. Friedman says the goal is making caregiving feel "more coordinated and less chaotic" by surfacing what matters at the right time without constant manual checking.

For the millions balancing jobs, kids, and caring for aging parents, that kind of support could transform daily life from overwhelming to manageable.

Interested families can join the waitlist for Luffu's limited public beta now.
