A fresh start for Fitbit founders
On Tuesday, the new startup “Luffu”—founded by prominent Fitbit co-partners James Park and Eric Friedman—launched its innovative wearable device, the “Luffu Link.” It is an LTE-connected smart health and safety band specifically designed to monitor the wearer’s overall physical and mental health. The device combines 24/7 continuous health sensing, instant voice journaling, geolocation tracking, and the ability to call for immediate help from trusted contacts without needing a smartphone nearby.
The device is currently available for pre-order at a promotional price of $250 USD (with an official retail price expected at $300), and shipments are scheduled to begin in early 2027 in three stylish color options: calm gold, onyx black, and silver blue.
Luffu Link smart band specifications
The Luffu Link band represents an advanced step within the company’s strategy to build an integrated smart ecosystem for family care. The band integrates directly with the Luffu health app launched earlier this year. The app runs on background artificial intelligence algorithms to collect and organize family health data, understand daily vital patterns, and monitor noticeable changes to help families respond early to any health emergency affecting their loved ones.
The band continuously gathers standard vital indicators, including physical activity levels, sleep quality, resting heart rate, calories burned, heart rate variability, and respiratory rate, with the aim of building a dynamic health profile that tracks changes over time.
Family care motives and AI analysis
The idea of founding Luffu stemmed from the founders’ personal experiences in caring for their families and elderly parents. They aimed to provide solutions that give families a clear and comprehensive picture of their loved ones’ health without burdening them with frequent follow-ups or making them feel closely monitored.
James Park said in an interview with TechCrunch: “When you become a family caregiver, you spend an enormous amount of time; studies show they spend more than 27 hours a week on average, which is a huge amount of time. We believe technology can reduce this burden, especially since current tools are very fragmented.” He added: “The band’s role is not limited to tracking alone; the secret lies in what artificial intelligence does with that data. It looks for patterns and changes—such as decreased activity or sleep changes after taking a new medication—to answer critical questions: What changed? Does this matter? Should someone be notified? Without overwhelming families with complex charts, many of which were designed during my work at Fitbit.”>
Interaction mechanisms and direct emergency alerts
The band allows users to press a dedicated button to record daily notes with their voice on the spot—such as medication schedules, disease symptoms, dietary meals, and mood—so the app automatically organizes them within the family’s health context.
Thanks to an independent SIM chip and GPS navigation, the band keeps contacts informed of the wearer’s geographical location, with the option to send a quick check-in notification by double-pressing the button. In emergency situations such as a fall, the user can press the button and record an emergency voice message—such as “I fell and hurt my wrist, can someone help me?”—so the band instantly sends the voice recording along with geographical coordinates, battery percentage, and updated vital indicators directly to authorized family members without requiring a separate cellular subscription.
Jewelry-like design and home aspirations
The Luffu Link band features a complete lack of digital screens. Park explained that this design choice is intentional for the band to act as a “quiet guardian” in the background all day, relying on an upscale design inspired by the world of fine jewelry to break away from the traditional look of sports trackers or bulky plastic medical alarms. The company also revealed it is working on developing a complementary smart home device to be unveiled later to enhance the smart family care ecosystem.
