I think one of the big ways my iPad has made a difference to my workflow is Siri shortcuts. I don't have an iPhone so this might be just as easy on an iPhone and not specific to iPad, but it's still something I think everyone should make use of.
Prior to using Siri shortcuts, when I would meditate in the morning this was my routine:
Now I do ALL of that without touching my device once.
All without even having to be next to my iPad. :)
Another example, I say "Hey Siri, start my workout" and it checks what day it is, and opens up my workout tracker app (Strong) and starts the right workout for the day. If it's a day I don't normally workout, it asks me which one I want to do, and then starts that one.
