Sometimes you want your app text to be smaller, so you can fit more content on a single screen. Sometimes you want it to be bigger, especially if you've been putting off buying those reading glasses. But until recently, if you had an iPhone, you had to choose one text size as the standard for all your apps.
Not anymore. In iOS 15, you can adjust text size separately for each of your apps. So you can, for example, keep the text small for your email, but make it a little bigger on Twitter – or vice versa. (Thanks to @OmarShahine for the info.)

First, you need to make sure the "Text Size" option is in your iOS Control Center:
Once done, it's simple to change the text size for each app:
And, of course, if you want to go back to standard text size, just go back to Control Center, select "Text Size" and move the bottom toggle to "All Apps". But be aware that you will reset all your apps to this text size.
