Luffu Link – Fitbit’s Founders Are Back With a Wearable Built for Seniors and Family Care

The people who helped put fitness trackers on millions of wrists are trying something different with their next wearable.

Fitbit co-founders James Park and Eric Friedman have introduced the Luffu Link, a screenless LTE health and safety band designed around family caregiving, independent older adults, and people who want health monitoring without wearing a traditional smartwatch.

Rather than trying to compete directly with the Apple Watch, Garmin or Fitbit on workouts and smartwatch features, Luffu Link focuses on something much more specific: helping families keep an eye on the health and safety of people they care about without constantly checking in on them.

The wearable is currently available for preorder for US$249.99, down from its listed US$299.99 price, with shipments expected to begin in early 2027. However, there’s an important limitation for Canadian buyers: Luffu says Link currently only works in the United States.

Luffu Link isn’t really trying to be another Fitbit

Despite its Fitbit connection, Luffu Link is quite different from the fitness trackers Park and Friedman became known for.

There isn’t even a screen.

Instead, the slim band quietly tracks health and activity in the background while using LTE, GPS and the companion Luffu app to keep family members connected.

Luffu Link tracks activity, steps, sleep, heart rate and heart-rate variability (HRV). The company says it uses that information to learn the wearer’s normal daily patterns and look for meaningful changes over time.

That makes the concept particularly interesting for families with older parents.

Rather than calling Mom or Dad several times per day just to make sure everything is okay, family members can potentially use Luffu to stay informed while allowing the wearer to maintain some independence.

A wearable designed with seniors and caregivers in mind

Luffu isn’t marketing Link exclusively as a senior wearable.

The company describes it more broadly as a device for families, caregivers and people who want additional health and safety monitoring.

But many of its features make a lot of sense for older adults living independently.

The band includes built-in LTE and GPS, meaning several important functions can continue working even when the wearer’s smartphone isn’t nearby. LTE service is included with the device and doesn’t require a separate carrier plan.

Wearers can press the physical button to request help from predefined trusted contacts.

There’s also a simple check-in feature: double tapping the device can let family members know that the wearer is okay.

Location sharing adds another layer of reassurance for caregivers.

This approach also avoids making the Link look like a traditional medical-alert pendant. Luffu has instead gone for a slim, jewelry-inspired design available in Halo Gold, Onyx Black and Sterling Blue.

Voice logging could be one of its most useful features

One of the more unusual Luffu Link features is voice logging.

Instead of opening an app and manually entering information, the wearer can press the button and record things such as medications, meals, symptoms, mood, notes and reminders.

That information is then synchronized with the Luffu app.

For family caregiving, this could be more useful than it initially sounds.

An older parent could quickly record that they took a medication, aren’t feeling well or noticed a new symptom without navigating through menus on a smartwatch or phone.

The broader Luffu platform is designed to organize family health information and surface useful changes or patterns to caregivers. Luffu launched its family-health platform earlier in 2026 before introducing the Link hardware.

Up to five days of battery life

Luffu advertises up to five days of battery life, although that figure comes with some fairly significant conditions.

The company’s estimate assumes 24/7 health tracking, a Bluetooth connection to a smartphone, several daily voice logs, GPS turned off and LTE primarily being used for help messages. Heavy GPS or cellular use can reduce battery life.

Fast charging is supported as well, with Luffu estimating roughly 20 minutes or more to reach 80% and a little over an hour for a complete charge.

The band is also rated for water resistance down to 50 metres, although Luffu specifically recommends avoiding showers, baths and environments such as hot tubs.

There’s a subscription

Here’s the other big catch.

Using Luffu Link requires a Luffu Family Plan subscription.

Luffu currently lists a standard Family Plan covering up to four members at US$19.99 per month, while an Extended Family Plan covering up to eight members is planned for US$29.99 per month. The company notes that pricing and plan details remain subject to change.

That makes Link considerably more expensive over the long term than its US$249.99 preorder price might initially suggest.

On the other hand, the subscription includes the broader family-health platform, and LTE connectivity for the Link doesn’t require users to purchase a separate cellular plan.

What about Canada?

Unfortunately, this is where Canadian Nerdfuse readers will need to wait.

Luffu explicitly states that Luffu Link currently works only in the United States, with its cellular service also limited to the US.

The hardware supports Android and iOS, with Luffu recommending Android 14 or later and iOS 18 or later.

There’s currently no confirmed Canadian launch date.

Why Luffu Link matters

We’ve seen plenty of wearables designed to tell us how many steps we’ve taken or whether we slept well.

Luffu Link is interesting because it approaches wearables from a different direction.

It’s less about optimizing your 10K time and more about answering questions such as: Is Dad okay? Did Mom remember her medication? Can she quickly tell us she needs help?

There are already medical-alert systems that address parts of this problem, of course. Luffu’s approach is to combine health tracking, family communication, location awareness and AI-assisted health logging in something that looks much closer to a modern wearable than traditional emergency hardware.

And the Fitbit connection makes this one particularly worth watching.

Park and Friedman helped establish the modern fitness-tracker category with Fitbit. With Luffu, they’re betting that the next useful evolution of wearable technology might not simply be collecting more health metrics—it could be making those metrics easier for families to actually use.

Whether Luffu Link succeeds at that will become much clearer once the device starts shipping in early 2027.
