Welltra.AI (Welltra) describes itself as an AI-first company focused on transforming digital health and wellness through advanced affective AI. Its core idea is simple but ambitious: everyone with a smartphone camera should be able to check their physical and mental state on demand, without buying wearables that go out of date each year. To do that, the platform relies on remote photoplethysmography (rPPG), a clinically validated method that detects subtle changes in facial skin tone caused by blood flow. By processing the RGB channels of a short video captured in ambient light, Welltra's algorithms extract pulsatile signals and turn them into readable health metrics.
On the physical side, the platform reports metrics such as heart rate and respiration rate (both described as FDA-approved metrics within its offering), plus pulse-respiration quotient, stress index, oxygen saturation, heart-rate variability, blood pressure, relaxation, a composite wellness score, shock index, cardiovascular disease risk, cardiovascular age and cardiovascular BMI. On the mental side, it applies AI-driven behavioral and vocal analysis for non-invasive screening of stress, mood, anxiety, cognitive function, attention, energy and early indicators associated with mild cognitive impairment or Alzheimer's. A key design claim is that the algorithm runs locally on the user's device, so no recordings or personal data need to be uploaded to Welltra's servers.
Welltra packages this capability as several connected products: a mobile app for contactless self-screening, the Ru'ya smart mirror that doubles as a health-screening assistant, and an SDK that businesses can embed in under three hours and run entirely on the edge. The company targets telehealth and clinics, corporate wellness, insurance and underwriting, and fitness and well-being teams, and says its technology is already used in localized trials and real-world deployments across the Middle East.
