Great app!

* Update: super surprised a how fast they responded as they were down fixing technical issues and it is up and running again within an hour. Couple hours ago this app wasnt working at all ! IT HAS BEEN and WAS working fine earlier yesterday eve, but then after loading, none of the features are accessible, and error message comes : "Something went wrong! UPS we are sorry :(. Try later. OK! " I was able to access to send a trouble report but I tried restart phone and did not fix it.*
In general this is a very good app for practicing and performing and has the most karaoke songs that other providers have. I am not totally satisfied with the lyric syncing in exact time with the music as pro karaoke providers do so well but for a phone app its great. I would like to see more song with guide or good model vocals. The fact that it has a complete self contained performance recording makes it easy to submit to karaoke contests. I have now even tried Red Karaoke on the Internet from my computer the functions are even better. It may be my computer or browser, but the functions wont load or do lock up sometimes. Also the pitch change function is not available or does not work for most of my favorites. Otherwise the features to review and modify your recording are good. You cant go back and modify a recording you saved. You have to delete and re-record one you dont like. If you want a song you dont find, they are pretty good about adding those you request but sometimes they drop some without notice, but usually for a better version. On my 4s iOS 9, I had problems with limited memory. Now running on iPhone SE, iOS version 10.1, 64 GB – no problem.
