How to Customize Button Shapes Per App in iOS 15

Apple introduced a dedicated Per-App Settings feature in iOS 15 that allows users to customize accessibility settings—including Button Shapes—on an app-by-app basis. This article provides a straightforward guide on how this feature works, why it is useful, and the exact steps to enable Button Shapes for individual apps without changing your system-wide display preferences.

What Are Per-App Accessibility Settings?

Prior to iOS 15, accessibility features like Button Shapes, Bold Text, and Increase Contrast were strictly system-wide toggles. Turning on Button Shapes added underlines or shaded backgrounds to navigation elements across the entire operating system, regardless of whether a specific app already had clear buttons.

iOS 15 resolved this limitation by introducing Per-App Settings at the bottom of the Accessibility menu. This tool lets you configure visual accessibility preferences for specific third-party apps, default Apple apps, or just the Home Screen.

How to Enable Button Shapes for Specific Apps

To customize Button Shapes for an individual application, follow these steps:

1. Open the Settings app on your iPhone running iOS 15 or later.
2. Scroll down and tap Accessibility.
3. Scroll to the very bottom of the menu and select Per-App Settings.
4. Tap Add App.
5. Choose the application you want to customize from the list of installed apps (you can also select "Home Screen").
6. Once added, tap the app's name in the Per-App Settings list.
7. Locate Button Shapes under the Display options.
8. Tap it and switch the setting from Default to On.

The changes take effect immediately within the selected app. If you ever want to revert the appearance, return to this menu and select Default or Off, or swipe left on the app in the Per-App Settings list to delete the custom configuration entirely.
