What's New in Mendi App

3.5.0

May 2, 2026

The Training tab has a new face, and your Mendi score has a new voice! We've redesigned the Training tab from the ground up: a decluttered layout that strips away visual noise and lets the information that matters come forward. Your Mendi score is clearer, easier to read at a glance, and easier to place in the arc of your training. We've also added  Mendi Score Insights: a short, honest read on where you are. Each score range comes with a plain language interpretation of what it means and how to build from it, so the number is never the whole story. Under the hood, we've tuned up performance and squashed a long list of bugs, so the whole app feels faster, steadier, and more reliable. As always we love to hear from you - email us at help@mendi.io

Still no iPad Support

Whilst I like using my Mendi I would much prefer to be sat at a table using an iPad rather than having to hold my iPhone. Hopefully this can happen soon.

Honestly, I think it’s a scam…

Basically if you live your head up, the ball moves up… move head down, ball moves down… they make it seem like you control the ball on the screen with your mind and that calms you down and provides neuro feedback… BS… I wasted all that money to basically tap a few current emotions and watch a ball move on a screen with some headband on that makes you think it’s providing neurological benefits. It’s pretty much impossible for the headband to read your oxygen levels the way that it’s designed….dont fall for the gimmick… the other reviews are probably paid!!!

It is ok

It kinda works

Day 1

Exceptional plus the Meditation Series is a Must!

Jury is still out

I’ve been inconsistent with use of this device because I don’t see much difference in my sessions. I will continue to try usage to improve my pre frontal cortex engagement. The annual subscription fees are excessive in my opinion which is also a deterrent. I will continue use until my current subscription lapses and probably put my device on ebay. I notice mendi has less than 500 reviews/ downloads which may indicate lack of market value/popularity
