What percent of the apps that came preinstalled on an iPhone do most people actually use?

For example I would never think of creating a spreadsheet on the small screen of an iPhone.

I use about 66 pc of what is installed, and have added quite a few more that i use in business or in travel. Many are redundant - I n do not need to have my photos stored in 3 different places - so first I disable redundant features. If the app's reason for living gets thin enough - it is gone. But I maintain several spreadsheets on my 8+. They are linked to my desktop, so major revising are fine there, but I often need their connect on the phone.
