Luffu Link, a new wearable from Fitbit’s co‑founders, offers all‑day health sensing, voice logging, and LTE emergency support for families.
Fitbit’s co‑founders have unveiled Luffu Link, an LTE‑enabled health and safety wearable that blends continuous biometric monitoring with built‑in emergency communication.
What Luffu Link Offers
The new band features all‑day heart‑rate and oxygen‑saturation tracking, a built‑in microphone for voice‑logged notes, and a dedicated LTE connection that can summon emergency services or alert pre‑selected family members with a single press.
Unlike many existing smartbands, Luffu Link operates without a paired smartphone, allowing users to stay connected even when they leave their phone at home or in a bag.
Design and Battery Life
Luffu Link adopts a slim, silicone‑wrapped profile reminiscent of Fitbit’s classic devices, but with a slightly larger display to accommodate the LTE antenna. The company claims a typical battery life of up to 48 hours with continuous health tracking and LTE standby mode.
Safety Features
The emergency button triggers a predefined message that includes the wearer’s location, vital signs, and a short voice note if the user can speak. Recipients receive a real‑time alert via a companion app or SMS, ensuring rapid response in situations where a phone may be unavailable.
- Continuous heart‑rate and SpO₂ monitoring
- Voice‑activated journal entries
- LTE‑based SOS alerts
- Companion app for family monitoring
Pricing and Availability
Luffu Link will be sold directly through the company’s website starting in October, with a base price of $199 and an optional $9.99‑per‑month LTE service plan.
The founders emphasize that the device is aimed at both health‑focused consumers and families seeking an extra layer of protection for children, seniors, or outdoor enthusiasts.
We wanted to create a wearable that could genuinely act as a lifeline, not just a fitness tracker.
The launch follows a broader trend of wearables adding cellular connectivity, a feature previously limited to high‑end smartwatches.
