Per-app settings allow you to enable accessibility settings on an app-by-app basis instead of applying them system-wide. This can be useful if, for example, you need your Messages app to have a bigger text size but not your Settings app.
This tip works on iPhones running iOS 16 or newer and iPads running iPadOS 16 or newer.
Open the Settings app, and select Accessibility.
Scroll down and select Per-App Settings.
Select Add App.
Select the app to add it to the list.
Once you’ve added an app, select it to access its available accessibility settings.
Here, you can enable, disable, and adjust a broad array of accessibility options to make the app easier to use, such as changing text size, inverting colors, reducing motion, etc.
