The latest update to LDS Hymns (1.6.1) fixes an annoying crashing bug, but also provides the Portuguese Hymns! Special thanks to Eurico Costa for his help with the translation.
Many of you have asked to help with additional languages. I would love to add more languages, but this is limited by the availability of the hymns in native PDF format (not scanned), which is only possible with the original music notation source content (which only the Church is likely to have). The only other language with these PDF hymns available is French. I'm hopeful that in the future more languages will become available!
