Sing! is an electronic application designed to replace your regular printed songbook. This app is perfect for those who enjoy singing, praying, or simply using their time on the go. With a rather dark and simple UI, Sing! minimizes possible distractions while still providing a quick and natural way of handling to navigate, zoom, and search.

Sing! can be used in churches, during mass, and other services. It currently includes only Latin texts by default, but additional songbooks can be obtained while inside the application. The available songbooks include Oratine latina, which features Roman Catholic prayers and songs in the Latin language, and Magyar katolikus népénekek [HU], which includes Hungarian prayers and songs based on Szent vagy Uram, Miatyánk, Glória, Hozsanna, and other songbooks.

The app also features interlinked songs and prayers from multiple books, with a quick navigation possibility if they exhibit a certain relationship, such as translation or different text for the same melody. Sing! is a handy feature for services in multiple languages or multi-language families. With Sing! on your phone, your songbook is never forgotten, making it a songbook of the modern age.
