Overview

Welltra AI is a mobile‑centric digital health platform that lets you capture a range of physiological and psychological metrics with just a phone camera or a smart mirror. The company presents itself as a contactless way to track heart rate, respiration, oxygen level, and other vital signs, while also offering conversational analysis for mental well‑being.

The core of its offering is Remote Photoplethysmography (rPPG). By analyzing the subtle changes in the RGB channels of a facial video, Welltra extracts heart rate, breathing frequency, and other FDA‑approved metrics in real time. Because the processing happens locally on the device, you do not need to upload any video or data to a server. The same approach is used for oxygen saturation, blood pressure, and heart‑rate variability, giving you a composite Wellness Score out of ten. The platform can also calculate shock index, cardiovascular risk, and vascular‑derived BMI, all from the same camera feed.

Welltra adds a layer of neuro‑cognitive screening through AI‑driven voice and behavioral analysis. After a short audio session, the system reports on stress, mood, anxiety, and early markers of cognitive impairment such as mild cognitive impairment and early Alzheimer's. The results are tied to a single app that consolidates all the vital and mental health data. They also offer a ‘Ru'ya' smart mirror that integrates the same contactless diagnostics into a home environment.

If you need a tool that fits on a smartphone and does not rely on wearables, Welltra's contactless vitals may appeal. For clinicians or corporate wellness programs that wish to embed the technology in a broader ecosystem, an SDK is available for rapid implementation and full on‑device processing. The technology does not require a cloud connection, protecting user privacy. The range of metrics is broad, but you will need to be comfortable with the platform's limits, such as lack of standardized pricing or clear guidance on which metrics are supportable in all lighting conditions. The company also emphasizes a new product suite; user adoption data and third‑party validation are not yet published.
