"Butlers Lives of the Saints" is an audiobook based on the Benziger Brothers 1878 edition of Alban Butler's famous work. It features short biographies of saints for each day along with reflections. This app, compatible with both iPhone and iPad, offers a glimpse into the lives of saints following the old Universal Roman Liturgical Calendar. Users can enjoy spiritual growth and encouragement by listening to these saintly biographies any time of the year.

The app allows users to download it for free and access some programs. Upgrading to the full version provides unlimited access to the complete series. The MP3s are streamed, saving storage space, and a connection is necessary for playback. For those interested in managing the MP3s themselves, a download service is available on the developer's website.
