I’m quite happy to use the smart phones for times, trackers etc when I’m on a simple journey, say from home to town and back. However on a day out or more complicated journeys I prefer paper timetables for looking for connections etc. .I did find the small area booklets that GNE issued until recently very useful. I also know several people who haven’t got a smart phone or find them difficult to use so they haven’t got any means of finding times.
