Diagnosing sleep apnea traditionally involves a complex, clinical setup that can be uncomfortable, time-consuming, and intimidating. PranaQ approached Pilotfish with a bold idea: to develop a lightweight, fingertip-worn device that could collect accurate sleep data in a home setting. The result was TipTraQ, a three-gram wearable device that uses PPG sensors to capture respiratory and cardiac signals. Designed for at-home screening and remote diagnosis, it leverages AI-powered data analysis to identify sleep apnea and other sleep-related disorders, eliminating the need for in-clinic testing.
