I've tried about half a dozen apps like this and Jogg is top of it's class. The voice clone's accent didn't quite sound like me (though it would have fooled people who don't know me well) I will be using my own voiceovers so its not a big deal for me. The quality is excellent regardless.

The videos generated so quickly, faster than promised. I found some flaws, like an occasional unwanted jumpcut, but nothing compared to problems with other apps and given the quality of Jogg I am confident they will improve rapidly. I quickly upgraded to tier 3.
