abckeypad app for iPhone and iPad

It is a patented keyboard that is intuitive because it is arranged in alphabetical order and can correct the error input character without erasing it by using the conversion key that switches input with the previous and next alphabet in alphabetical order. The keyboard is arranged in alphabetical order, so it is easy for children or foreigners who are not familiar with QWERTY keyboards to use.
