Very Happy with this App, we have put many people on to it. We had an Issue with it dropping out and going to the Ipad Home Screen. We emailed Karafun and they fixed it within 5 Days, I was very impressed.
I've been singing for quite a while now on KaraFun and I love it! The quality is good, their windows application is really powerful and the library includes thousands of karaoke songs ready for playback as soon as you know what to sing. Their mobile app is also a killer is you want to throw a party with friends on the go.
