XL Keyboard is a utility application designed for iPhone users who require a keyboard with larger keys for improved accessibility and ease of use. It allows users to customize their typing experience by adjusting the keyboard size, selecting from various layouts such as QWERTY, AZERTY, and more, and enabling features like autocorrect and spell checking. Users can also change the keyboard's color and select their preferred emoji skin tone. With its user-friendly interface, XL Keyboard aims to enhance typing efficiency on mobile devices.

The app supports multiple languages, allowing users to switch between installed system languages seamlessly. It includes features like a thumb keyboard option for larger devices, click sounds for key presses, and the ability to add words to the dictionary to refine autocorrect functionality. Notably, XL Keyboard does not collect user data, ensuring privacy while typing. However, it does not support dictation input, which may be a consideration for potential users.
