Many families share the job of watching over an aging parent or relative. A new wristband from the founders of Fitbit wants to make that job a little easier. It isn’t on sale yet, and its claims come from the company.
Consider a single dad we’ll call Marcus, who lives in Denver and checks on his mother two states away. (He’s an illustration, not a real person.) He calls most nights. When she doesn’t pick up, he worries for an hour. The Luffu Link caregiving band is aimed at that kind of gap.
Fitbit co-founders James Park and Eric Friedman started Luffu earlier in 2026, and Luffu Link is its first hardware. It’s a screenless band that tracks some health signals in the background and shares them with family members you choose. TechCrunch reports that Luffu targets family caregivers, older adults who want to stay independent, and health- and safety-conscious adults. Park told TechCrunch that family caregivers spend over 27 hours a week on caregiving on average. That figure came from Park, and we couldn’t trace it to a study.
What it does, and what to watch
| Works well | Be careful |
|---|---|
| No screen. Luffu says it looks more like jewelry than a medical device, in halo gold, onyx black or sterling blue. | Not shipping yet. Early 2027 is an expectation, not a delivery date, and preorder buyers pay before anyone has tested the final product. |
| Tracks activity and sleep, resting heart rate and heart rate variability, breathing rate and calories burned (TechCrunch). | Neither outlet describes how accurate the heart rate, breathing or GPS readings are, or whether they’ve been clinically validated. |
| Built-in LTE and GPS work without a nearby phone. A double press sends a check-in to family. | Both reports say LTE is included. Neither says whether the app charges a subscription. |
| A help request sends a voice message, the wearer’s location, battery level and health data such as heart rate to trusted contacts. | Android Authority says families control what is shared and with whom. TechCrunch found no description of data privacy or sharing controls. |
| Press and hold to record a voice note about a symptom, medication, meal or mood. The band records only while the button is held (Android Authority). | Battery life of up to five days per charge (Android Authority) is Luffu’s own claim, as are the features and privacy claims. |
After a voice note, the Luffu app organizes it. TechCrunch says AI in the app looks for daily patterns and flags notable changes.
Verdict
There is no product to test yet. TechCrunch based its report on company statements and an interview with Park, and Android Authority notes that battery life, features and privacy claims are Luffu’s own, not independent test results. The band isn’t a medical device as described, and it isn’t a substitute for a doctor, a nurse or emergency services. Anyone worried about a loved one’s health should contact a health professional.
Why It Matters to You
The band is meant for family caregivers and for older adults who want to stay independent. A quick check-in or help request could tell relatives that someone is fine or needs them, even when the wearer has no phone nearby. But it’s a promise from the company, not something you can use today, so check the privacy policy and any app costs before you preorder.
Price and timing
Preorders are open at $249.99, which Luffu’s site calls a $50 instant saving. Android Authority lists the expected retail price at $299.99. Shipping to the US is expected in early 2027. TechCrunch says LTE data is included, so you don’t need a separate carrier plan, and neither outlet gives the cost of any ongoing service. The Luffu app is in public beta and is expected to be broadly available in the US later in 2026, Android Authority reports. The company is also developing a home device but has shared no details.
When will it ship? Luffu expects to ship in the US in early 2027. That date can change.
Does the wearer need a phone? Not for the band’s check-ins and help requests. TechCrunch says built-in LTE lets the wearer send a help request without a phone. Family members use the Luffu app.
Can the band diagnose a health problem? No source says it can. It tracks signals such as heart rate and sleep and flags changes. Talk to a doctor about any health concern.
