Tether Unveils QVAC Health to Aggregate Wearable Data With On-Device AI

• Tether launched QVAC Health to unify fitness and wellness data using on-device AI.
• The platform organizes inputs from wearables, apps, and trackers.

Tether has launched QVAC Health, a device-level wellness system that builds on the company’s earlier work in on-device artificial intelligence. In May, we reported that Tether unveiled QVAC, an AI platform designed to run directly on users’ hardware without relying on cloud infrastructure. The company is now extending that concept to personal wellness by targeting long-standing fragmentation across fitness and health applications.

According to a December 10 blog post, QVAC Health aggregates biometric readings, workout records, nutritional logs, and medication reminders into one encrypted interface that remains functional even offline. The company argues that users today depend on isolated apps and proprietary systems that rarely communicate, which forces sensitive health information through external servers owned by device manufacturers.

Tether Pushes A Unified Approach To Wellness Data

Tether CEO Paolo Ardoino stated that the new platform serves as a neutral ground for information from multiple wearables and wellness apps. He emphasized that the tool is meant to counter the closed data environments maintained by major tech vendors while giving individuals direct control over their fitness history. He added, “We are breaking down the walls between Big Tech ecosystems so you can own the full picture of your health.”

QVAC Health relies on on-device AI models and natural-language processing to allow conversational interaction with health entries. Users can report symptoms, meals, supplements, or workouts verbally or in text, and the system structures the information automatically. The platform also supports private medication tracking with encrypted reminders.

Moreover, an early-stage computer-vision component allows users to photograph meals for calorie and macronutrient estimates without sending images to external servers. The company plans to extend these capabilities with proactive guidance generated entirely on-device, including sleep suggestions or recovery prompts.

Local Processing Anchors Tether’s Broader Expansion Efforts

All AI models are downloaded peer-to-peer and processed locally, enabling correlation across devices such as watches, smart rings, and fitness apps. Tether said upcoming updates will introduce Bluetooth Low Energy support so QVAC Health can read raw sensor data directly from wearables, bypassing manufacturer APIs.

The launch comes as the company explores a significant expansion plan. As previously reported in September, Tether is evaluating a potential funding round that could reach up to $20 billion, with Cantor Fitzgerald advising on the matter. Ardoino did not refute the rumors. He confirmed that the company is assessing partnerships aligned with its push into sectors beyond stablecoins, including AI, energy, and media.

Beyond software, Tether is also moving aggressively into robotics. It invested €70 million in Generative Bionics, a spinoff of the Italian Institute of Technology. The company has spent more than two decades developing humanoid systems, producing 60 prototypes, and assembling a team of 70 engineers and AI specialists.

Funds will go towards the development of Physical AI, a production facility, and edge-driven robotics systems for logistics, healthcare, and manufacturing. Generative Bionics is planning to debut its first robot at the CES 2026 event in Las Vegas.
