The main components of the interface are a notepad sheet with the target word written on it either in letters (LEARN modes) or in question marks (PRACTICE and TEST Modes), several scattered letter cards and card slots in a number that matches the number of the letters in the target word. The target word is spelled either in upper- or lower-case letters.

The goal of each activity is to assemble (“spell” or “write”) the target word in the card slots using some of the letter cards.

The letter card can be dragged using simple gestures. Once the dragged card is near the appropriate slot the application places the card in the slot.

Application settings (sound cues, response to shake motion, practice or test mode, level, letter case, and background), help and contact form are available via the Settings reachable through PRESS&HOLD button. An additional feature is a selection of different background pictures.


  • LEARN Mode offers children to practice spelling by relying on both audio and visual prompts.
  • PRACTICE Mode helps children learn by testing their knowledge in spelling words relying only on the audio prompt. The trick here is to “write” a word without a visual prompt. The child listens to the audio prompt to make the word. The audio prompt can be heard as many times as needed by tapping the field with question marks.
  • TEST Mode focuses on testing children’s accuracy providing them with SCORE. Children have to rely only on the audio prompt. The trick here is to “write” a word without a visual prompt. The child listens to the audio prompt to make the word. The audio prompt can be heard as many times as needed by tapping the field with question marks. You may choose the number of words to be tested and scored in the SETTINGS: 5, 10, 15, 20 or 25 words. If a wrong letter was dragged to the slot, you may UNDO the move by tapping the Undo button in the upper left corner of the screen.

You may choose any spelling list, including custom spelling list, to use in any of the modes.
