It might be cultural differences, but I found the Divineoffice.com audio versions to be painful to listen to. The dramatic whispering in the way they read the psalms and readings made it sound, to my ears, as if they were making fun of the text, which I’m sure was not the intention.
The Universalis App gives me everything in the currently approved official translations for my country, and is convenient, loads quickly, holds everything offline (which makes a huge difference to me), and has convenient other options to do with the text. I don’t see why “uses the official translation” would be an advantage of the surgeworks app, when Universalis does that too, and in fact allows you to choose other approved official translations from other countries, which means I don’t have to use the American translation, but you can choose to.
Maybe you’re only looking at the free app, as opposed to the paid-for version of the web version? The free app has a different translation of the psalms, for copyright reasons. The paid-for and web versions have the Grail psalms.
