The application On the Wings of Faith (SAF) is a collection of 655 hymns that allow Christians around the world to praise the Lord in song. It offers the possibility to the Christians of the EPC to learn the questions of the catechism as well as the hymns of the ACH (Christian Association of Men). Moreover, SAF allows to add our favorite hymns as favorites. What sets it apart from its predecessors are its neat and pleasant interfaces. SAF incorporates both references from other hymns such as Shalom, Bulu, Bassa, Hymnes et Louanges, as well as the corresponding melodies.
