One app has almost anything a Catholic could want: iPieta.
This is a partial list of what they have:
Douay Rheims bible, linked to both Haydock commentary and St Thomas Aquinas’s Catena Aurea-- and you have the option of English, Latin, or both, either interlinear or side-by-side
Calndars with readings, gospel is linked, for both OF and EF.
But wait! There’s more!!!
Prayers
and a section with saint’s lives, catechismS, council documents and papal encyclicals, and many good Catholic books like Introduction to the Devout Life…
and the Summa Theologica by St Thomas Aquinas.
ETA and you can download matching audio for quige a number of things on there, but I don’t think you can get an audio of the Bible. However, I believe that Librivox has the Douay Rheims in audio, you could download that onto iTunes, then sync onto your phone, or get a download manager app and dowload directly onto there. (I have two: Goodreader and Download Manager, you really only need one for both audio and reading. I like both of these.)
