N-Back Origami: AR Memory Game

I saw research saying that single n-back is just as effective as dual n-back for increasing working memory, and I personally find it much more pleasant, so I tested 7 apps from the app store to see if they have this feature. Of those, this one was my favorite. The graphics are clean and memorable. It takes a bit to get used to the shapes, but once I named them all, it was easy and fun to play. I paid for the full in app upgrade to have the ads removed. At first the ads didn't go away but then they stopped so I think it just takes a while to kick in. The high score tracker doesn't seem to track my high scores correctly, but that's my only complaint. Other than that, it works very well. Personally, I'm not interested in the AR feature, I find it easier to focus in the normal nice, but I guess it's a fun novelty.
