The app includes five themes: Neutral, Colorful, Strawberry, Purple Rain, Marine and Custom.

In addition, Keeble offers multiple keyboard layouts:

  1. Simplified ABC offers an ABC keyboard and leaves out all the difficult, less important keys. It is intended for beginning users who are still exploring letters and who should not be distracted by keys they do not need.
  2. Simplified QWERTY is a standard keyboard, leaving out all the difficult, less important keys. It is intended for beginning writers who should not be distracted by keys they do not need.
  3. QWERTY is the standard keyboard layout.
  4. QWERTY extended is optimized for iPad Pro.
  5. Scanning - ABC offers a simplified, ABC keyboard for users with fine-motor challenges who access the keyboard through switch scanning.
  6. Scanning - Frequency of use is a research-based keyboard layout that offers letters based on frequency of use: the most frequently used letters are placed at the beginning of the keyboard, saving switch scanners lots of time.

Aside from picking a theme and a keyboard label, you can also select a preferred font, coding color for the vowels and define if the letters should be always capital or dynamic depending on if the Shift key is used.
