Luffu Link: A Family Health Band That Connects Everyone

Most fitness trackers care about one person. Luffu wants to change that. Created by the same people who started Fitbit, this new system thinks about the whole family. James Park and Eric Friedman launched Luffu in February. It began as a simple app where people could track things like meals, medicines, doctor visits, and symptoms. Now it has grown into something bigger.

The Luffu Link is a screenless wristband that works on its own 4G LTE connection. That means you do not need your phone nearby. It has GPS built in, so you can share where you are or send a quick check-in to family. The band tracks sleep, activity, heart rate, calories, and breathing. Then it uses AI to learn your patterns and warn you if something changes. It has one button. Hold it to record voice notes about your health. Press twice to let family know you are okay. Everything gets organized in the Luffu app, where you can even make a profile for your pet.

People can preorder the Luffu Link right now for $250 in the US. That price includes beta app access, a charger, and two band sizes. It comes in halo gold, sterling blue, and onyx black. Shipping starts in early 2027, and after that the price goes up to $300. The band lasts five days on a charge and takes about one hour to recharge. It works with Android 14 or later and iOS 18 or later. You also need a family plan. A plan for four people costs $20 a month or $200 a year. A bigger plan for eight people costs $30 a month. The LTE data is included with no extra carrier needed.

Some people think Luffu Link is only for older adults. That is not true. It is meant for everyone. Adults between 35 and 60 can use it to manage kids, aging parents, pets, and their own health. Active adults over 65 can get discreet safety support without wearing an emergency pendant. Younger adults can start with basic tracking and still benefit from the safety features. Families decide what gets shared and with whom. Luffu is also building a home device to help families coordinate care across different households. That is expected later this year. Park and Friedman said their own caregiving experiences inspired them to build a single place for families to track health and safety together.
