How does Mendi work?

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.

Returns & Exchanges

The Mendi Headband comes with a 60-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.

10 minutes a day. A lifetime of sharper mental clarity.

Mendi's brain-training technology is built on decades of Functional Near-Infrared Spectroscopy (fNIRS) research used in neuroscience labs across North America and Europe.

Improvement in sustained focus

42%

Reduction in perceived stress

31%

Improved mood and emotional balance

16%

Better general wellbeing

51%

Results are based on aggregated in-app data and self-reported outcomes from thousands of users who completed eight weeks of Mendi neurofeedback training. Improvements were measured using validated scales (ACS, WHO-5, PSS-10, GAD-7, PHQ-9). Individual results may vary.

Introducing Focus Areas
Build a Habit of Reflection

Build a Habit of Reflection

Every few weeks, Mendi invites you to check in with yourself. These short, research-backed check-ins take just a couple of minutes, creating a habit of awareness and keeping you connected to your goal as you continue to train.

Your Progress, Visualized

Your Progress, Visualized

Once you complete your first check-in, your results appear in the Profile tab: your most recent result, the date of your last check-in, and a growing visual of where you've been. Scroll through past results, spot patterns, and export your data any time.

Grow with Intention

Grow with Intention

This isn't just about tracking metrics. By checking in regularly, reconnecting to your goals, and watching your mental well-being evolve, you're building something lasting: through reflection, awareness, and action. Whether you're just starting out or coming back after a break, this is your space to grow.

Built on fNIRS Neuroscience

Stronger every session. Proven by your data.

Mendi creates measurable, lasting neural change. Each training session strengthens the prefrontal cortex through neuroplasticity. The science behind it has been in neuroscience labs for 40+ years.

Train Through Play

Your brain controls the game.

The Mendi app turns your real-time brain activity into a training game. When your focus increases, your score climbs. The feedback is instantaneous, and the changes persist long after each session ends.

"Repeated practice strengthens the neural connections involved in performing the task. With practice, feedback, attention, and motivation, we can master any skill and become experts in our chosen fields."

Frequently Asked Questions

  • Mendi uses fNIRS (functional near-infrared spectroscopy) to measure blood flow and oxygenation in your prefrontal cortex in real time. That signal feeds into a 10-minute daily game where you train your brain to activate and sustain focus. The more you train, the stronger and more consistent that activation becomes.

  • 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!

  • Yes. Mendi sits on your forehead and uses near-infrared light to read brain activity. No electrical stimulation, no needles, no discomfort. The same fNIRS technology has been used safely in neuroscience research for over 40 years.

  • Most users begin noticing changes within 2 to 4 weeks of consistent training. Measurable improvements in focus, stress resilience, and mental clarity are typically reported after 8 weeks. Results vary by individual and training frequency.

  • 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.

  • Yes. The Mendi app supports multiple user profiles, so the whole family can train on one device. Each person tracks their own progress separately.

  • No. The Mendi app is free with no ongoing subscription fees. You pay once for the device and get full access to all training features.

  • Mendi comes with a 60-day risk-free trial. If you are not satisfied within 60 days of purchase, you can return it for a full refund.

  • Mendi works with iOS and Android smartphones via Bluetooth.

  • Meditation apps guide you through a practice but cannot measure what your brain is actually doing. Mendi reads your prefrontal cortex activity in real time and gives you objective feedback on your performance. You are not just following instructions. You are training a measurable skill.

  • Yes. Mendi is built on 40+ years of peer-reviewed fNIRS neurofeedback research. Independent researchers at Stockholm University validated Mendi's sensor accuracy against BioPac fNIR100 lab equipment. Published studies on fNIRS neurofeedback training show measurable improvements in sustained focus, working memory, and stress resilience.
