Make the text sizes of the application larger or smaller without affecting the default settings of the operating system.
iPhone has excellent accessibility features and has been adopted by many popular applications; the dynamic type, which allows you to increase or decrease the text size of the operating system and all supported applications, is a good example. Starting with iOS 15 and iPadOS 15, you can independently specify the text size for each application (even the home screen), thanks to the convenient new text size control in the device control center. (IOS 15 and iPadOS 15 are currently in public beta, and the stable version should be launched in the fall.)
How to add the Text Size control to the Control Center
First, you need to add the text sizes control to the control center (the switch that shows when you swipe down from the top right corner of the screen).
Open the “Settings” application on your iPhone or iPad and go to the “Control Center” section. Tap the green plus icon next to the “Text size” option to add it to the control center. You can now use the three-line control icon to rearrange the text sizes controls.
How to change the text sizes for a specific app using Control Center
Now that the text size control has been added, open the application you want to change the text sizes, and swipe down from the upper right corner of the screen to open the control center. Touch the “Aa” text size icon.
At the bottom, switch to the “(application name) only” option. By default, this function will change the text sizes of the entire operating system. Now you can swipe up or down to change the size of the text. It can range from 80% to 310%.
Swipe up from the bottom of the screen to exit the control center. You will immediately see the updated text size.
You can revert to the default size at any time. To perform this operation from the control center, click the text size button (“Aa”), switch to the corresponding option, and return to “100%”.
