A much improved version of my Sing Harmonies app is now at the App Store: it has a better look, improved functionality, and we've added nineteen new songs, available via in-app purchase. So far the most popular songs have been Amazing Grace, Rolling in the Deep, and Hallelujah. The least popular? Baby: sorry, Justin Bieber. The Sing Harmonies website has song arrangement info, keys, and more.![](//d10j3mvrs1suex.cloudfront.net/u/47237/666da3fe6a27d5645467d59a8359e2b18802f456/large/cropped-2-0-screenshot.jpg?1410569610)
