"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!" (Jonny Brennan, YFC) - - - - - - - - - - Perfect for churches, small groups, kids groups, music rehearsals or even your own personal use, iSingWorship is an amazing resource designed to engage and inspire people in worship. Using iSingWorship is just like having your own very experienced band playing with you as you sing or lead worship. Download a song from the growing built in library and you can take out the vocal, repeat a chorus, end by going back to verse 1, break down into a quiet instrumental section to talk or pray over, or sing a chorus with just the drums playing. iSingWorship uses SATT™ (Smooth Audio Transition Technology) for incredibly smooth and natural song section changes. 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. Songs may also be played back in several alternative keys making the app useful for a wide variety of different situations. 4 free song previews available. - - - Compatible with iOS devices running iOS7 or later (additional AirPlay compatibility available on devices that support AirPlay mirroring).

Sitting down with your instrument and turning on a metronome (click..click...click...) at 60 bpm to repetitively play the same scale over and over again although effective, is not the most exhilarating experience that you're just longing to get back to every day. We understand that, and that's why we created Scale Junkie! With Scale Junkie, you can have a fun immersive experience while playing your scales to music specifically created to keep you engaged, and interested the whole entire time! You're not just practicing to a metronome any more, you now have a full band playing along with you!
