There seem to be people who think that just about everything, including breathing too loud, is “not appropriate for Mass”.
Use what you want. It’s not their business. If you are concerned about distracting others, try to sit away from them. And make sure your sound is off.
The TLM crowd includes a good many people who would like to turn the clock back to 1940 or whenever, and of course nobody had electronics then, so you may get some fisheyes, but again, unless you are going there to make friends rather than worship Our Lord, it’s no one’s business but your own.
I currently use my mobile phone to pull up daily readings because almost none of the Church-provided missals have them and I do not have time to lug my own missal around to daily Mass when I’m rushing just to get the Mass itself in at odd hours like before or after work or on a lunch break.
