My memory isn't exactly what it used to be, and I've read that you can do exercises to improve it, so I downloaded Memory Trainer on a whim. Hey, it's free, so why not give it a shot, right?
The app leads you through a sequence of activities that exercises your "spatial and working memory, focus, chunking, and concentration skills." It starts off rather easy but gets more challenging, and so far the app has only confirmed that I have a horrible memory. However, I can only hope that by continuing the exercises I'll see some results. At the very least, it's a fun and interactive app.
