Keyboard Master is an input method and application launcher for Android devices. This app allows you to change the input method of a specific application, allowing you to use a different keyboard. This is useful for users who have to switch to a different application every time they want to type in their favorite language. It is also perfect for users who need to type in their native language but have to switch to the English keyboard to do so.

Keyboard Master works as a system app. This means that it will not require you to install it as a regular application. You will not need to open the app and click on the "Enable Keyboard" button to enable it. This app does not need any additional hardware, and it will work on all Android devices, even those with older versions.
