"A brilliantly thought-out tool for worship musicians." (Matt Redman, Worship Leader and Songwriter) “iSingWorship is a brilliant and creative resource...particularly exciting for people who are keen to lead worship but don’t have the musicians and resources to do so.” (Tim Hughes, Worship Leader and Songwriter) "I have used it in schools, in church, in small groups, on my own, and blaring it out on a bus going in front of the Olympic flame! This has to be an essential app for Youth and schools workers!"

Plug iSingWorship into your TV/projector with a cable (or wirelessly via AirPlay) and view song lyrics on a large screen. Also included are a variety of inspirational backgrounds that can be displayed behind the lyrics. All songs have been recorded by award winning producers and musicians in the most congregation friendly keys possible.
