Wearable First Look
Quick Verdict
The people who invented the modern fitness tracker are taking another swing at it. James Park and Eric Friedman, who founded Fitbit in 2007 and sold it to Google, announced Luffu Link on August 25: a screenless band with built-in LTE that tracks your health, records voice notes at the press of a button, and lets family members check on each other without anyone carrying a phone. Preorders are open at $249.99, with an expected retail price around $299.99 when it ships in the United States in early 2027.
The catch comes in three parts. The band is many months from shipping, so every impression so far comes from announcements rather than wrists. The full experience appears built around a Luffu Family Plan at $19.99 a month, and what the band does without it is not yet documented. And Luffu has said nothing about whether your health data will sync to Apple Health or Health Connect, which decides whether Link joins your health stack or becomes another silo. Interesting device, wide open questions.
Who Is Behind It
Luffu is the second act of the two people with the strongest claim to having created this category. Park and Friedman started Fitbit in 2007, took it public, and sold it to Google in a deal that closed in 2021. Google has since folded Fitbit hardware into Pixel devices and pushed the brand toward screenless trackers like the Fitbit Air.
The founders resurfaced in early 2026 with Luffu, initially as a family health app that pulls a household's health and safety information into one place, with AI organizing the data and surfacing changes. Link is Luffu's first hardware, and it slots into that family-first frame rather than chasing Whoop-style athletic recovery.

Two design choices stand out. First, the cellular radio: most screenless bands are phone tethered, while Link talks to the network on its own, which is what makes the family check-in and help features work for a kid at practice or a parent who does not carry a smartphone. Second, the voice button: pressing the band and saying "took my blood pressure meds" or "big pasta dinner" is a genuinely lower-friction logging interface than opening any app, and Luffu says the AI files those notes into something structured.
One important boundary Luffu itself draws: the help button alerts your chosen contacts with your location and a voice message. It is not an emergency service and does not call 911.
The Real Positioning: Care, Not Performance
Luffu is aiming Link at family caregivers, independent older adults, and health-conscious adults, and describes the band as "a quiet guardian" on your wrist. That is a different market from Whoop, Fitbit Air, or the smart rings, which sell recovery scores to people who train. The closest comparison might be a hybrid of a screenless tracker and a family-safety product, a lane that has been dominated by kids' watches and medical alert devices, neither of which anyone wears happily.
That framing also explains the subscription. Family location sharing and LTE service cost real money to run, and $19.99 a month for up to four people is priced like a family utility rather than an athlete's analytics platform. The open question is the one Luffu has not answered: what does a Link do if you never subscribe? Until that is documented, budget for the plan as part of the price.
The Questions That Matter Before You Preorder
Where does the data go? Nothing in the launch coverage mentions Apple Health or Health Connect export. The original Fitbit was famous for keeping data inside its own walls, and Google's Fitbit still routes everything through its own app. If Luffu repeats that pattern, your sleep, heart rate, and HRV history will live in one more silo that the rest of your health stack cannot see. If Luffu opens it up, Link becomes a legitimately interesting input device, especially that voice log.
How good are the sensors? Nobody outside Luffu has tested accuracy yet, and early 2027 is a long time in a category where Whoop, Oura, Garmin, and Google will all iterate before Link reaches wrists. Treat every capability above as a claim, not a review.
Will it exist as promised? Park and Friedman have shipped hardware at scale before, which puts them well ahead of the average wearable startup. But preordering anything eight-plus months out is a bet on a roadmap, and pricing, features, and dates announced in August can move by launch.
Should You Preorder?
Wait, unless the family-safety features are exactly what you have been looking for. The screenless-band category already has shipping, reviewed options today: the Fitbit Air, Whoop, Amazfit's Helio Strap, and Luna Band all exist now, and our guide to the best screenless fitness trackers compares them. If the appeal is specifically a band your whole family wears so everyone can check on each other without phones, Link is the first credible product aimed at that, and the preorder price saves about $50 if you are comfortable with the wait.
For everyone else, the rational move is to let it ship, let reviewers test the sensors, and let Luffu answer the sync question. The band's own history is the argument for patience: the founders' last company shipped sixteen years of hardware, and the interesting version of this product is the one that survives contact with real wrists.
Where Vora Fits
Vora is built to work with whatever you wear: it reads from Apple Health and Health Connect and turns the combined picture of your sleep, training, nutrition, and recovery into daily decisions. Whether Luffu Link can join that picture depends entirely on the export question Luffu has not answered yet. If Link writes its data to Apple Health or Health Connect, it will slot into Vora's device-agnostic setup like any other tracker, and its voice-logging button would pair naturally with the way Vora already handles voice logging.
Until then, the practical guidance is the same as for every new wearable: do not buy hardware on the assumption that its data will be portable. Check which wearable metrics actually sync to Apple Health before committing, and treat any device that keeps your data to itself as a subscription you pay with your history. The screenless wave keeps producing interesting hardware; the winners will be the ones that let your data leave.
