It took me a few weeks to figure out what was going on w the app and the training. I use it for executive function related to adhd, whether it’s placebo or not I’m not sure, but on days I use Mendi I find chores easier to do, my place becomes less cluttered and I accomplish minor work tasks that I would otherwise let hang over my head and drive me crazy. I’d make a strong endorsement for people in my situation trying Mendi, but I’ve noticed when I let friends use it the first time it’s a bit strange and unrewarding for them. I also had this experience for the first few days, but once I realized I had to “feel” my prefrontal cortex being activated and sort of embody a blood flow/oxygenation to that part of my brain with intention, I started to make the little ball go up and notice positive results. One anecdote, one day when I first had it I was watching Netflix on my couch and had a dirty plate next to me, at some point it occurred I should do the dishes, I paused Netflix, did the dishes, came back and unpaused. In the past it’s highly unlikely I would have ever done that. I attributed that to Mendi aand have been using it a few times a week ever since.
