It won't help at all. The problem is that Apple seems to hate explicit buttons, so you never know what tapping something will do. Here's an example in the phone app:
- in the contacts tab, tapping a contact will show details
- in the call list tab, tapping a contact will call them
There is no way to know ahead of time. You have to try it out, and then remember that the two tabs behave differently.
I have accidentally called people when I just wanted to look at their contact details more than once, and I've been using an iPhone for 15 years or so.
