Mendi - Brain training is an Android application developed by mendi.io. It falls under the Lifestyle category with a subcategory of Health & Fitness. This program focuses on brain health, recognizing its importance in overall well-being. By using functional near-infrared spectroscopy (fNIRS) neurofeedback, Mendi detects changes in the brain's local blood flow and oxygenation in response to neural activation.

The fNIRS signals are processed with proprietary algorithms to create simple and visually comprehensible feedback signals. The Mendi headband, equipped with fNIRS sensors, is placed over the forehead to measure oxygenated blood flow to the prefrontal cortex (PFC), a critical brain region responsible for executive functions such as focus, working memory, emotional processing, and decision-making. With repeated training, lasting structural and functional neuroplasticity occurs, leading to improved mental acuity and brain health.
