The Keres Keyboard App was designed to allow users to enter common phonetic characters into iOS devices, including iPhones and iPads running iOS 8 or later. This app adds the ability to type Keres directly into your devices text fields, including word processing/note taking, social media, and messaging apps.
The characters are arranged into a single keyboard. The vowels are clustered together, as are the consonants, numbers, modifying markers, and punctuation.
The Keres Keyboard App also includes installation instructions and directions for enabling specific keyboards.
