Love my Mendi

Mendi has been a game-changer for me. I usually do a session before my language course, a 10- minuter feels like chugging a virtual coffee.

Mendi uses functional Near-Infrared Spectroscopy (fNIRS) technology to measure and provide real-time feedback on your brain's activity, specifically targeting the prefrontal cortex (PFC). This region is crucial for executive functions like focus, decision-making, and emotion regulation. By training with Mendi, you strengthen neural pathways in this region of the brain.


The Mendi Headband comes with a 30-day money-back guarantee from the date of receipt, allowing you to return the product if you're not satisfied. 



Additionally, the device is covered by a one-year hardware warranty, which provides a replacement if the product malfunctions or breaks under normal use conditions.


How it works

Making the Invisible, Visible

What if you could see your brain health improve in real-time? With Mendi, you can.

  • Step 1

    Place The Headband Across Your Forehead

    The soft Mendi headband is fitted with non-intrusive sensors that bring your brain activity to life. As you place the headband across your forehead and start the game, Mendi begins to measure oxygenated blood flow in response to neural activity in your prefrontal cortex.

  • Step 2

    Start The Mendi Neurofeedback game

    The Mendi headband makes brain training tangible by visualizing your neural activity in the Mendi neurofeedback game. Make the ball rise and earn points. The ball’s movement upwards alongside streaks in collecting points indicates an increase in brain activity.

  • Step 3

    Track Your Progress + Build a routine

    Measure progress, compare results over time, and track improvements with the Mendi Score. The Mendi score is a representation of how well you activate your prefrontal cortex when training, compared with your historical data, how diligently you stick to the habit of training.

FAQs

Have Questions?

Mendi is a portable neurofeedback brain training system that combines fNIRS technology with behavioral science to enhance brain health. The Mendi system includes two core components:

  • The Mendi headband which uses functional near-infrared spectroscopy (fNIRS) to monitor oxygenation in the prefrontal cortex (PFC).
  • A brain training mobile app which allows you to visualize and practice controlling your brain activity in near real-time.


With Mendi, you can measure, track, and strengthen your brain health. Consistent Mendi training enhances the brain’s executive functions, including sustained attention, emotion regulation, stress management, and working memory—fostering a healthier brain and greater mental well-being over time.


Thousands of users report positive changes in their brain health and mental well-being through regular Mendi use. The most frequently reported benefits include enhanced focus, improved emotional regulation, and higher-quality sleep. Mendi can support brain health across several key areas:

  • Mental well-being: Brain training is essential for mental health and is commonly used in clinical settings for preventive care as well as by individuals managing stress, anxiety, ADHD, and sleep issues.
  • Performance: A healthy brain is foundational for optimal performance. Many individuals and organizations use brain training to improve focus, decision-making, and productivity.
  • Overall health: Brain health impacts every part of the body. Just as with prioritizing physical fitness, maintaining cognitive health is essential for overall well-being.

Read more about how our community benefits from Mendi in our user stories.


New users should gradually adjust their neurofeedback training to suit their individual needs. During the first week, we recommend three 5-minute sessions to become familiar with the app and headband.

Over time, you can increase session length. Aim for 4–5 sessions per week, gradually extending them to 10 or 15 minutes as you progress, until you feel comfortable with daily sessions. Be mindful of mental fatigue, and prioritize quality over quantity by scheduling sessions under calm conditions for the most accurate feedback.


Mendi is suitable for all age groups, though we recommend it for ages 5 and up. It is particularly helpful for those seeking to improve focus, emotion regulation, and working memory as part of a healthy brain training routine.

Please note that Mendi is not a certified medical device and is not intended to diagnose or treat medical or mental health conditions. If you have, or suspect you may have, a medical condition, please consult your healthcare provider before using Mendi.


Get started in less than 30 sec:

  • Put on your Mendi headband and open the Mendi brain training app. Make sure it fits snugly on your forehead to measure brain activity accurately. 
  • Find a dim spot to avoid bright lights, this helps ensure a clearer signal.
  • Select your training duration and settle in. Relax and focus on the ball, aim to make it rise. Each time a star appears, think of it as instant feedback that you're “doing it right.”

Bonus Tip: Try a quick session before work, studying, or sports. It’s a great way to boost focus and mental sharpness!
