Is there an Audulus 3 Demo version for Mac?

Not sure if this is the right place to post this question but, I am a very happy Audulus 3 user on my iPad Pro 12.9". I am thinking about using it on my MacBook Pro. But I have heard and read that there are some idiosyncrasies when using it with certain OSX versions/hardware configurations, etc.

A friend told me there was a demo version of Audulus 3 for the Mac. Is that true? I would like to try it out to make sure it will work for me.
