When Im home I prefer the four volume LOH, but when Im in my office I like this app. When youre praying privately it doesnt matter what translation you use--prayer is prayer. If you want to use the official prayer wording, then use Latin. But this app wont work for you if you absolutely have to use the same English as in the printed volumes.
The app is constantly being improved.
Having said all this, I would like to see crosses marking the Gospel canticles as a reminder to make the Sign of the Cross when reciting those parts.
