Update to Liber Pro (iOS app for the Liber Usualis)

    Dear friends on the forum, I am going through a bit of a rough patch between jobs at the moment. In this interim, I've been focussing on some self-employment activities while applying for jobs. I don't generally talk about my apps here on the forum because that seems self-promoting and solicitous; however, in my present circumstance, I would like to mention that there is an update to Liber Pro out that includes in-app purchases for annotations and search. If you have an iOS device, Liber Pro is a cost-effective and approachable entry into the Liber Usualis. The app even calculates the current feast day from a given date, making it easy to navigate to specific propers. As an example, you open the app, tap the calendar tab, see the current feast day, and tap to go directly to it in the Liber. Annotations allow for markup, and a text-based search helps find more obscure chants and passages.

    A bit of background on the making of Liber Pro...

    I was briefly a seminarian at Our Lady of Guadalupe Seminary (FSSP) in 2008, and I quickly learned that navigating the Liber Usualis is not for the faint of heart. There are a lot of ribbons and bookmarks for a reason, and seminarians frequently have multiple holy cards in their Libers because sometimes there still aren't enough ribbons to handle hopping from place to place. My first interactions with Musica Sacra occurred when I discovered its online PDF of the Liber. I made contact with CMAA, and Jeffrey Tucker answered my questions about the PDF being in the public domain and that I could use it to build an app for the Liber. If you view the first page in Liber Pro, you'll see the document it is based on comes from CMAA. My goal in creating the app was to make the Liber easier to use and carry around ... and to be able to create any number of bookmarks.

    A number of folks in my own choir (including our director) use this app (and another of my iPad apps for sheet music called Forzando) to eliminate carrying around thick binders of music, and they have had success having all the music for a given Mass readily available at a few taps of the finger, including propers, ordinaries, Mass settings, and motets. (These choristers still use hymnals, as those contents are copyrighted.)

    Even if you are not interested in Liber Pro, I would appreciate your prayers.

    I've used it for years as a light weight option for practicing while traveling, or when I might need the Liber but don't have room to carry the whole book. It's great! Thanks for it, and I'll check out the update!

    And you're welcome to talk about the app a little here. Certainly other users talk about publications and engraving projects.

    Janet, thank you so much for your interest. I do occasionally get requests for an Android version, but I don't have plans to port it to another platform at this time because it would be a much larger undertaking than it might first appear. Just about everything is different on Android vs. iOS, even the programming language. While the data, concept, and basic design remain the same, it would basically require a rewrite of the app.
