About This Software

Let me introduce the world’s FIRST and BEST overlay utility to prevent 3D motion sickness!

My ex-girlfriend — who just so happens to be my wife now — used to suffer from severe 3D motion sickness.

I couldn’t share the games I had loved my entire life with her.

That was the moment I knew I had to do something.

So I built this utility — for her. And now, for all of you.

Don’t lose the love of your life over something as small as 3D motion sickness.

This program may slightly cover part of your screen…

But it might just show you what true happiness looks like!
