Very useful and informative! I have really enjoyed using this app and would recommend this to others as well! Thanks to the developer for such great work!

Update - 2016-02-28 I hope this gets updated soon. It would be really nice if it took advantage of the new fluid layout methods of iOS 8 and later so that it could leverage the extra screen real estate of the iPad Pro. ------- This app makes the Liber Usualis very approachable. Calendar integration is fantastic, especially for those trying to wade the then more eclectic rules regarding the structure of the pre-Vatican II Church year. This is straight scan of the Liber, so don't expect it to behave like a traditional ebook. No text flow. You pan from column to column. I have used this app for a while on the iPad2, but it looks fantastic on the Retina display of the new iPad. No update required to gain the extra resolution. Kudos the the developers for getting this right. My only gripe is that the app can be persnickety when moving from page to page. It tries to "help" you go to the top of the next column, but it often feels more like a tug-of-war. It works much better, however, in portrait mode.

This update brings Liber Pro to full compatibility with iOS 8 and 9, and the larger iPhone screens. Thank you. There are also several welcome adjustments. On an iPhone 6 with iOS 8, the screen is now well used and makes it much more efficient for liturgical use. The zoom is indeed a bit quirky, but this is much less required than before on newer screens, as in landscape mode, the page is perfectly readable and accessible. Hopefully that can be fixed in a subsequent update. The combination of a reliable calendar with all the pages of the Liber Usualis is just brilliant.
