Hinário CCB Virtual PLUS Nº4 e is an educational app designed for members of the Congregação Cristã no Brasil, offering a digital version of their hymnal. With 480 official hymns from hymnal Nº5 and 450 from Nº4, it serves as a convenient tool for worship and gatherings. The app also includes 6 and 7 official choirs from the respective hymnals, alongside 12 teachings from Nº5, a preface, a general index, and a correlation of hymns from the Old to the New Testament.

Additionally, users can access offline radio (TuneCCB) with lyrics, and download and view sheet music in various formats. The app operates offline, ensuring accessibility without internet connectivity, though it may experience performance issues on devices with less than 1GHz processing power. It features a neutral dark gold interface, although it is important to note that it does not replace traditional hymnals used in worship settings.
