Karaoke2U iPhone App, page-104

Yeah I saw that post too, but I can't see anywhere where 30 days are free.
There's a couple of free songs there you can choose though.

TBH maybe I'm missing it, but all the app really allows me to do is sing to a backing track and save it.
There's no analysis of how you did, or scoring, or comparisons or anything.
I really don't see the point of the App or what it has over other apps of its kind.
PlayStation and Wii games released years ago seem better.
Is anyone seeing anything else other than a recording feature?
