Fitbit founders launch AI-powered wristband to monitor health of whole family

September 4, 2026 - 10:40

The team behind the original Fitbit is back with a new wearable aimed at the entire household. Their latest creation, the Luffu Link, is a slim, wireless wristband built to monitor the health of several family members at the same time, not just one person.

Instead of pairing the device to a single profile, the Luffu Link uses a shared tracking system. The band can identify who is wearing it through a quick tap or a simple voice prompt, then switches to that person's health data. This means parents and kids can take turns using the same device throughout the day without mixing up their step counts, sleep stages, or heart rate readings.

The artificial intelligence inside the band goes beyond basic numbers. It learns each person's normal patterns and sends gentle nudges when something looks off, like a restless night or a spike in stress levels. For parents, there is a separate dashboard that shows trends for each child, but it keeps the details simple so it does not feel like a medical chart.

The founders say they wanted to move away from single-user gadgets that sit in a drawer after a few months. By making one band that serves the whole family, they hope to build a habit that everyone can share. The device charges once a week and works without a phone nearby, storing data until it syncs later.

No price or release date has been announced yet, but the company says it is in final testing with a small group of families. The focus is on everyday wear, not clinical accuracy, so the band is designed to be comfortable enough for a child to forget it is there. Whether it can match the original Fitbit's success remains to be seen, but the idea of a shared health tool is a clear shift from the personal-device model that dominated the last decade.
