Todo Mongol Bichig is a free keyboard app for Android developed by Suragch Development. The app is designed for users who prefer to write in the traditional Mongolian vertical script, also known as Todo Script or Clear Script.

The keyboard layouts include Todo and Mongol, and users can switch between them by long-pressing the keyboard key. The app also provides word suggestions based on your typing, and the data is stored on your device, ensuring your privacy.

One of the unique features of Todo Mongol Bichig is the vertical text input window, which allows users to type in the proper orientation. Since most other apps do not support vertical script, the app also allows users to share the text they type as an image.
