Keyman is a free iPhone application developed by Summer Institute of Linguistics Inc SIL. It allows users to easily type in over 1,700 different languages on their iPhone, iPad, or iPod. With Keyman, you can install all your language keyboards as a system keyboard and use them in every app on your device.

Keyman offers a wide range of language keyboards, including Amharic, Tamil, Greek, Hebrew, Sinhala, Syriac, Tibetan, Hindi, and many more. This makes it a valuable tool for users who need to communicate in languages other than English.

One of the key features of Keyman is the ability to build custom keyboards using Keyman Developer and load them onto your phone. This allows users to create personalized keyboard layouts that suit their needs.

Additionally, Keyman provides a smooth and optimized typing experience with predictive text for a growing set of languages. This makes it easier and more efficient for users to type in their desired language.

Another useful feature of Keyman is the built-in browser, which displays your language even if iOS doesn't support it. This ensures that users can view and interact with websites and content in their preferred language.

Please note that in order to install a new keyboard, Keyman requires the "Allow Full Access" option to be switched on. However, for privacy and security reasons, users can switch this option off once the keyboard is installed.

Overall, Keyman is a valuable tool for individuals who need to type in multiple languages on their iPhone, iPad, or iPod. With its wide range of language keyboards, customizable layouts, and predictive text, Keyman provides an efficient and user-friendly typing experience.
