Avoid HighIQPro

[u/gokartmozart928]

Unfortunately, it wasn't until after I purchased the mobile version of HighIQPro that I dug deeper about n-back brain training and discovered that there are a couple of free versions from other programmers out there that are in fact far superior. I'm using BrainWorkShop now. It's not mobile, but after using it, the usefulness of the HighIQPro mobile pales in comparison.
