About

Split Words

Read full description

Split Words is designed to assist children with dyslexia and auditory processing difficulties in improving their reading skills. This app provides an exercise to enhance auditory processing, auditory memory, and auditory awareness by teaching them to split complex words into sub-words. Children with dyslexia often find it challenging to read words with more than four sounds. Split Words tackles this hurdle by training young minds to break down larger words into smaller chunks, making it easier for them to read and piece together complex vocabulary. The simple yet engaging activities within the app have been carefully crafted to support children in their reading journey. We are committed to continuous improvement, and your feedback is highly appreciated. If you have any suggestions or feature requests, please reach out to us directly through the in-app feedback system.
