While Apple has expanded the range of customization options available to iPhone users over time, there is one aspect of the iPhone’s system font that users cannot alter. However, users who have an iPhone running an earlier version of iOS 16 can now change the font on their device thanks to a new tool created by a developer.
Zhuowei Zhang, a developer, created a tool that altered the system font of an iPhone by taking advantage of a security flaw in iOS 16’s predecessor. To use the tool and modify the system-wide font on an iPhone, it must run iOS 16.1.2 or earlier because the security flaw Zhang used to create the tool was patched in iOS 16.2.
You can find the iOS version on your iPhone by going to Settings -> General -> About and looking at the information there. You won’t be able to downgrade if you’re using iOS 16.2 because Apple stopped signing iOS 16.1.2 over the weekend.
The tool can be downloaded as an IPA file from GitHub. Users can choose from various fonts, such as Comic Sans MS, Fira Sans, DejaVu Sans Mono, and others, to change the font on their iPhones. Your iPhone’s appearance will change if you use the tool, as shown in the screenshots below that Zhang has provided.
Users are strongly advised to update to iOS 16.2 as it contains many new features and significant security fixes, such as new options for the iPhone 14 Pro’s always-on display, Apple Music Sing, the new Freeform app, and more. Using our guide, you can learn more about iOS 16.2.
