New wearable combines health tracking, location sharing, and emergency communication to support users and family caregivers.
James Park and Eric Friedman, Fitbit’s founders, have launched a new wearable through their startupLuffu, moving beyond traditional fitness tracking with a device designed around health, safety, and family care.
Called Luffu Link, the screen-free wearable uses LTE connectivity to stay connected even when the user doesn’t have a smartphone nearby. The device is aimed particularly at family caregivers, older adults, and people who want an additional layer of safety in their daily lives.
Health monitoring without a screen.
Luffu Link continuously records several health and wellness indicators, including activity, sleep, resting heart rate, heart-rate variability, and breathing rate. Rather than simply presenting users with a collection of statistics, Luffu says its system is designed to identify changes in everyday patterns. The accompanying Luffu app uses AI to organize information and highlight changes that may be relevant to a person’s wellbeing. Users can also record voice notes about symptoms, medication, meals, mood or other health-related information, allowing those details to become part of their broader health history.
The screenless design is deliberate. Instead of functioning like a conventional smartwatch, Link is intended to remain unobtrusive while operating in the background.
Built for family safety.
One of the device’s more distinctive features is its focus on communication between family members. Built-in GPS lets trusted contacts receive location information, while a double press can serve as a quick check-in.
The LTE connection also means users can request help without relying on a phone. For example, someone who has fallen or needs assistance can press the device’s button and send a voice message. The alert can include their location, battery status and selected health information, giving family members additional context. Luffu Link is currently available for pre-order at $250, with the company expecting shipments to begin in early 2027. Its planned retail price is $300. The device will be offered in three finishes: halo gold, onyx black and sterling blue.
For Park and Friedman, the move represents a return to wearable technology with a different objective: not simply measuring activity, but helping people stay informed, connected and safer in everyday life.
