First Suggestion: Peripheral vision is about the seeing outer/peripheral squares I wish the 4 x 4 grid left the inner four squares blank or shaded. This would make focusing on the center easier so the player would not keep shifting their eyes(This means the 4 x 4 square would have just 12 numbers.)Second suggestion: a 3 x 3 option would be great for kidsThird: touching the correct square with my finger also distracts the process. If the two axis were labeled like a chess board and the app had voice recognition, I could use my voice to give the correct square (a1 to d4)

When I first started practicing this game, it was a little infuriating. But now I’ve seen positive results in my alertness, short-term memory, and productivity.

I got this app through a recommendation. I wanted to improve my peripheral vision for reading and really in general. This app definitely helps me do that, just get it, be patient and consistent and you will notice results, I have in just 3 days and I don’t plan on stopping using this app. I recommend this app to anyone who is a reader and is generally interested in self improvement.

This is the best! Can you add reverse numbers and upside numbers too?
