The Ottoman Keyboard is a free Android app developed by Hayrat Neşriyat that enables users to type in Ottoman Turkish with ease. This keyboard is based on the TS13206 document published by the Turkish Standards Institute in 2006, which outlines the layout of the Ottoman Turkish Keyboard.

The keyboard is designed with the common letters in both the Latin and Arabic alphabets placed at the same position. Non-common letters are placed in positions based on their sound and shape similarities. The keyboard also includes all the symbols necessary for writing in Arabic and Persian. The Ottoman Keyboard is an excellent tool for those who need to write in Ottoman Turkish and want a keyboard that is easy to use and accurate.
