The Brotherhood Hymnary is a comprehensive app contenting all Brotherhood Hymns. This mobile app is an offline application and requires no internet connection to use after the initial download and also has the following capabilities: Hymns can be favorited, searchable either by hymn numbers or first line indexes, zoomed in and out for better viewing, flipped between text and sol-fa notation views, and swiped right to un-favorite hymns.
I trust that you will find this app very useful and convenient in your daily activities within the Kingdom.
