Researchers at the University of Memphis have developed an app that tracks physical wellbeing through continuous analysis.
CuesHub, uses biometric AI models to help people monitor their daily health. The technology, developed by researchers at the mHealth Center for Discovery, Optimization, and Translation of Temporally-Precise Interventions (mDOT).
The startup was founded by Dr. Santosh Kumar, director of mDOT, and Dr. Tim Hnat, former chief software architect of mDot in 2022.
The app is available for Samsung Galaxy and Fossil smartwatches and uses research developed over 16 years. 122 participants engaged in a 100-day study called Mobile Open Observation of Daily Stressors (MOODS) using the technology.
The study tracked users’ stress. Participants noted a stronger awareness of their stress levels and were able to identify consistent stressors. They were also able to find new ways to manage stress.
“Using workload heart rate — a physiological measure linked to both physical and mental demand — the technology delivers real-time insights into when users are approaching fatigue,” the university said.
The app tracks changes in heart rate to determine pending stress and exhaustion, and is primarily being used by Memphis’ frontline medical workers.
“By receiving personalized cues for rest and recovery, healthcare staf are gaining a clearer understanding of their physiological stress levels and learning strategies to better sustain their energy and resilience,” the university said.
App users will also receive daily tips to “help build stress resilience.” The app also doesn’t use or store users’ personal information.
