Fitbit’s founders launch Luffu Link, a screen-free band for family caregiving

Fitbit co-founders James Park and Eric Friedman have launched Luffu Link, a screen-free health and safety band that helps families keep up with a loved one’s wellbeing.

The wearable combines everyday health tracking with voice notes, location sharing, and a way to contact trusted family members. It is built for family caregivers and independent older adults, but can be used by anyone who wants an easier way to stay connected to the people who care about them.

How it works

At first glance, Luffu Link works like a screen-free fitness tracker. It monitors activity, steps, sleep, heart rate, and heart-rate variability throughout the day. But instead of turning that data into another set of scores, the Luffu app looks for changes in the wearer’s usual routine.

The band also has a button for adding context by voice. A parent could record that they started a new medication, noticed a symptom, or were feeling unusually tired. Luffu saves that update alongside their health data, which could help explain a later change in sleep or activity.

The same button helps families stay connected. Wearers can send a help message or double-press to let selected contacts know they are okay. Built-in LTE and GPS allow those features to work without a phone nearby, although help requests go to trusted contacts rather than 911 or emergency services.

What’s behind the launch

Fitbit helped make tracking your own health a daily habit. With Luffu, its founders are shifting the focus to the people around you. Instead of producing another score, the band is meant to help families notice when something changes and decide whether they need to check in.

The timing makes sense. Nearly one in four American adults is now a family caregiver. While most consumer wearables focus on personal optimization, Luffu stands out for turning its attention to the often-overlooked work of caring for the people around us.

Where to get it

Luffu Link is available to preorder and is expected to ship in early 2027. It requires a Luffu Family Plan, starting at $19.99 per month for up to four members.
