Fitbit co-founders James Park and Eric Friedman have launched Luffu Link, an LTE-enabled health and safety band designed to offer comprehensive monitoring of physical and mental health. Priced at $250 for preorder with shipments expected in early 2027, the device supports continuous health sensing, voice logging, GPS location tracking, and emergency assistance features—all independent of a smartphone. It comes in three color options: halo gold, onyx black, and sterling blue, expanding Luffu’s goal of creating an intelligent family care system alongside their AI-driven Luffu health-monitoring app.

The wearable aims to ease the burden on family caregivers by automating health tracking and providing meaningful insights rather than overwhelming users with data. Luffu Link collects standard wellness metrics such as activity, sleep, heart rate, heart rate variability, and breathing rate, then analyzes patterns to identify significant changes potentially linked to new medications or health conditions. Users can capture real-time updates via voice, which the companion app then organizes within a family health context to keep caregivers informed without constant check-ins.

Equipped with GPS and LTE connectivity, the device ensures users can share their location and request help from trusted contacts quickly, without needing a phone or separate carrier plan. A double press enables discreet check-ins, and an emergency button lets wearers send voice messages, location information, battery status, and vital health data to family members if assistance is needed. This blend of continuous monitoring and on-demand communication positions Luffu Link as a quiet yet effective guardian designed to keep wearers safe and connected.

Distinct from other screenless health wearables, Luffu Link draws inspiration from jewelry to blend seamlessly into everyday life, emphasizing subtlety and comfort. The company is also developing a complementary home device to extend their family care ecosystem. Following the initial launch, the retail price will rise to $300, suggesting that Luffu aims to balance affordability with advanced health and safety capabilities for caregivers, older adults, and health-focused individuals.
