The app is designed to stimulate the child to watch the action on the tablet display and to complete the tasks in an interactive way. The visual and audio treatment of the app supports the eye-hand coordination. KEY FEATURES - 4 TASK LEVELS and 4 VISUAL LEVELS The app can be customized depending on the child’s individual skills. The visual levels are manifested through the types of illustrations viewed (V1 – V4). The task levels are marked G1 – G4. - SKILLS SECTION The Skills section records the child's progress within the app. Thus, the parents and therapists can monitor the development of the child’s skills over time. - The possibility of the child accidentally switching off the app is prevented.
