App is stable. Brain blood flow training is something the world sorely needs. The user interface is cluttered and poorly designed, but the core function is easy to use, I would give it 5 star except one problem. They hide the results from you. The purpose of the device is to increase your baseline oxygenation in the frontal lobe. It takes a measument of this at the start of every session when calibrating but it won't show you this reading, so you have no idea if it is helping or not.

Thanks for the great feedback! Mendi uses continuous wave fNIRS, which tracks changes in oxygenation, not absolute values—so the baseline isn’t shown to avoid confusion. We’re working on clearer progress visuals and improving the UI. Please email us at support@mendi.io if you have more questions. Best, Mendi Team

There are way too many glitches with the app in which you cannot connect the headset to a session. This time no matter what I do even delete and then re install, the app still won't connect and on top of that lost the data because it won't let you log in, however the q&a gas lights you to make it you believe that it was your mistake but they actually don't have an option to actually log in because when reinstalling they ask for email and then pw set up. So frustrating!

Hi CJ, we’re rolling out a new release that includes a fix for the login issue—expected by Monday. As for the device not connecting, this is typically due to either the app running in the background too long or missing location permissions. Let us know if it persists after checking those - we are here to help!

I recently got a Garmin and discovered that Mendi has been counterproductive to my meditation practice. After 2 years, still having no control over the ball apparently raises my heart rate and stress levels through pure annoyance and constantly feeling like I am failing at something that is clearly just not possible. On the plus side, now that I know this, I have found a new way to use it. I do like the music, so I now shut off the sound effects, let the music play, close my eyes and meditate.
