I use the Universalis app on my smartphone (Android), my PC (Windows 10), and my Amazon Fire tablet. It's very convenient and very reliable. It's also available on iPhones, Mac, Kindle, Nook, and eBooks.
I noticed two new things now available on the Universalis app: Lectio Divina and an enlarged form for the Morning Prayer. The Lectio Divina is based on the Gospel reading of the day. The enlarged form for the Morning Prayer adds the readings from the Office of Readings and the Gospel of the day's Mass. I really like both features but the enlarged form of the Morning Prayer is perfect for me.
The app costs $10.99, $12.50, or $24.50 depending on your options. Once you get the app downloaded you don't need to be online. If you get the registration code, you're set for life.
Books are expensive. The Catholic Book Publishing Corporation publishes fine books for the Liturgy of the Hours but they've never been updated. It still contains the original English translation from 1976 with the old collects that are no longer used at Mass. It's sad but the reality is that publishers don't really see a big market for these books. It looks like we won't see any new books until 2025 when the second edition is, supposedly, due. I'm going to be really old then so I'll just go ahead and use the Universalis app now.
