1. Overview Phakchi is a new type Thai Keyboard that runs on both iPhone and iPad. There is a standard Thai keyboard in iOS. But it is a little difficult for Thai language learners to use it for some reasons like below.(1) There are a lot of characters and symbols on the standard Thai keyboard, and they are arranged randomly. So its not easy to find the character that you want to input.(2) There are some similar characters in Thai consonant characters.

The vowel screen includes 15 vowel symbols, 4 tone marks and other symbols like an ellipsis and a repetition mark. If the prediction comes into play, the screens change automatically.
