How 10 minutes of training rewires your brain
-
Measures blood flow and oxygenation in the brain to track attention, decision-making, and executive function in real time.
-
The app converts your brain signal into a live training game. When your prefrontal cortex activates, the game responds, creating a direct feedback loop that teaches your brain to focus on command.
-
Repeated training strengthens the neural pathways behind focus over time. The more you train, the more automatic and effortless concentration becomes, even off the device.

How to use
Put on Mendi
Position the headband comfortably on your forehead. Sensors auto-calibrate in seconds.
Train through play
Open the Mendi app and start a training session. As you focus, oxygen-rich blood flow in your PFC increases, and each game responds in real time to your focus.
Watch your score
After each session you'll receive a focus score. The more activated your PFC, the higher it goes. Train 10 minutes a day and your scores climb.
