What do I need to see on my phone that I can’t when I am doing my taxes or even more so planning a trip - which I do a lot of?

I launch the Delta app as a Delta loyalist (Platinum Medallion) to book my flight. I then launch the Hilton app (I am Hilton Diamond) and compare prices/convenience with hotels with Hyatt (I am Hyatt Explorist).

The only exception was when we were looking for an AirBnb for an extended stay in Costa Rica next year.
