Blueberry uses brain sensing (fNIRS) to understand your internal state and context sensing to understand your environment. Together, these enable you to gain deeper insight into how, why, and when your mind activates during the day. With head up information, you can understand how your mind responds throughout the day.

Blueberry uses functional near infrared spectroscopy (fNIRS) to measure relative change of blood oxygenation in the brain. Our algorithms process fNIRS and contextual data to extract information about users’ mental states. Beyond the basic physiological measurements estimations (heart rate and pulse rate variability).
