The founders of Fitbit are back with a new project — and this time, it’s not about tracking your own steps.
James Park and Eric Friedman have unveiled Luffu, a new health and safety platform designed to help families stay on top of everyone’s wellbeing. It covers kids and parents, as well as partners and even pets.
Luffu is being positioned as an “intelligent family care system”, starting with an app and expanding into hardware later on. The idea is to reduce the mental load that often falls on one person in the family. This is usually the one juggling appointments, medications, symptoms, and check-ins. Luffu achieves this by pulling everything into a single, shared place.
Unlike most health tech, which focuses on individuals, Luffu is built around the reality that health is shared. The app gathers and organises information across the whole family, learning what’s normal over time and flagging meaningful changes that might need attention. It’s designed to work in the background, surfacing insights when something actually matters rather than bombarding users with data.
Park says the idea grew out of his own experience caring for parents remotely after Fitbit. During that time, he tried to piece together health updates across different portals without the feeling of constant monitoring. Friedman echoes that sentiment. He describes the chaos of managing care across three generations and notes how easily your own health can fall to the bottom of the list in the process.
At launch, Luffu will focus on a handful of core experiences. These include “guardian moments” that proactively highlight changes, effortless health and medication logging via voice, text, or photos, and plain-language health questions that draw on your family’s shared data. Users will also be able to selectively share information with caregivers or relatives. Notably, privacy controls are baked in from the start.
AI plays a big role here, but Luffu is keen to stress that it’s not just another chatbot layered on top of health data. Instead, AI is used across the system to organise information, spot patterns, and provide guidance that reflects real family life — not generic advice. Importantly, users remain in control of what’s shared and with whom.
The name Luffu comes from an Old English word for love, which neatly sums up the pitch: caregiving as something deeply human, not transactional.
Luffu is now live with a waitlist for a limited public beta, with plans to grow into a broader ecosystem over time. For Park and Friedman, it looks like a return to familiar territory — but with a much wider definition of what “health tech” should actually do.
