Disappointed. No option to re-record a single line or passage, so you need to be a one-take wonder or keep restarting. Audio feedback not working for me. From a design POV unclear what all video filters and EQ effects do, and video annoyingly gimmicky. It had the song I wanted on premium but I need audio and line re-takes to do it. Will likely go back to other karaoke app. Song had lines during an instrumental too, ruined a take for me! Not too usable for me.
