I love magic squares, but to me a magic square has always been part magic trick and part skill. Personally, I never could find the right justification to use it. “Hey everyone, wanna see a math trick?”

I ended up writing a motivational speech integrating the magic square as an example to illustrate my point. I went as far as having an android app made so I can concentrate solely on speaking, instead of worrying if my math skills will fail me.

I know of one other magic square app and am just wondering if more exist? Just trying to be as thorough as possible. Thank you!

I recommend and use myself only the app brain 1.0. Highly recommended but too rarely used.
Just my two cents.

Brain 1.0 and the Cent are both obsolete now.
