Available in the iTunes store, StarMaker Karaoke touts itself as the only karaoke app with real Auto-Tune capabilities. Users can sing and record over 300 songs into their Apple device, with the option of sharing the creation on social networking mediums like Facebook and Twitter.

The program also offers new tunes every week, with lyrics included to prompt singers as they record their renditions. Purchasers can switch from two Auto-Tune settings including Hip Hop and Magic Tune, with the former intended for rap joints and the latter to touch up regular vocals.
