Fitbit brings Luffu App for family health

New platform uses AI to help families track health, share updates, and get proactive alerts, all in one easy-to-use app

Fitbit co-founders James Park and Eric Friedman are back with a new mission of helping families take care of each other’s health more easily. Their startup, Luffu, is an AI-powered platform that centralizes health information for the entire household, including pets.

Instead of each family member tracking health separately, Luffu creates a shared health timeline. Users can track medications, appointments, lab results, vitals, and more, all in one app. The AI quietly works in the background to spot changes and send gentle alerts, so families know when something needs attention without being overwhelmed by notifications.

A standout feature is the app’s natural-language support. Families can ask questions like, “Has Mom’s sleep pattern changed this week?” or “Did the dog get its medicine today?” and get straightforward answers. The AI interprets all the shared data to provide helpful insights, making it feel like having a personal health assistant for the whole family.

Privacy remains a priority. Every family member chooses what information to share, keeping personal data secure and under control.

Luffu is currently in a limited beta release as a mobile app, with plans to expand to connected devices later. The founders hope it will ease the daily burden on caregivers, millions of whom manage family health with scattered notes, portals, and apps.
