I have iBreviary, too. I actually have a dozen or so apps that are probably 90% repetitive, but after resisting for years, I finally paid for the lifetime license for Universalis because of the options they offer and that everything is presented in order, no “page flipping” to various sections. That’s true of iBreviary also for the Hours, but not for Mass, as I recall.
Edit to add: looks like my comments are repetitive, too! I’ve made similar posts elsewhere and forgot where I shared what! Appropriate faux pas for my cake day, I suppose! Now to find the apps for the senility-challenged.
