Why doesn't Apple Card provide running subtotals for each transaction?

If you have no faith in the security of the Apple Card then stop using it, cancel it and go on with your life.

Insider manipulation from who, Goldman Sachs? What are Master card people? People that are that leery should be using some kind of accounting software, financial software, so the items can be compared at beginning of statement, to close of statement and then adjusted for carryover charges and pending charges. A double entry could be manipulated too.

I don’t think more than one or two of my credit cards offer what you want.
