Bagan is a free keyboard that allows you to type in Zawgyi, the most used language in Myanmar.
Bagan Keyboard supports both Zawgyi and English, so it will be easy for you to type in the language of your choice. It is also designed to be easy to use and to provide a good user experience. It features an auto-suggestion and auto-correct system, which should save you time and energy. The app is pretty smart and learns from you - so the more you use a particular term or phrase, the more it will suggest these via the auto-suggestion or auto-correct features. It learns from your typing habits and subsequently gives you the option to finish your sentences for you.
