There are always a few things that change depending on circumstances. For example, I added the Apple Watch app when I was given an Apple Watch as a gift. I had a number of camera apps that I finally evaluated and kept ProCam and MS Pix. The Music folder moved to the home page when I retired and finally had some time to play. And yes, I have two calendar apps. One is for my schedule, such as it is, and the other for my wife’s. She has a dog walking business and if I kept a single calendar, I wouldn’t be able to find my events. Bob.
Some of you may see all of these iPhone screens as looking the same, but if you gave me that screen I would be lost because it isn’t mine. Small differences are big to the user in the iOS world.
