About

Read and Colour

Features
Read full description

Read and Colour is a first reader story app with colour-in illustrations and tap to read words. It is designed by qualified teachers to encourage independent reading in pre-school and early primary school aged children. Being teachers and having young children of our own, we struggled to find a 3-6 age reading app that ticked all the boxes so we decided to write our own. We discovered from other parents with young kids that, like us, they wanted an app that had: - no in-app purchases - no adverts - nothing locked - didn't need internet connection - accessible to young children - encouraged independent reading - helped pre-school kids to get a head start with learning the sounds of all the letters As well as the first reader story with 10 colour-in illustrations, Read & Colour has the additional functionality of tap the sound, sound practice, shape practice and tap to read common words. Features: Read and Colour - toggle between tap to read words or tap to read sounds - 10 illustrations to colour - read and colour remembers how each drawing was coloured Sound Practice - children press the buttons to hear the sound of the letter, helps them to associate the two Common Words - allows children to practise reading a word and then tapping it to see if they are right Tap the Sound - the child is asked orally to tap a particular sound. Tap the correct one and get a well done! Shape Practice - this feature is designed to help children become familiar with the sounds of the letters of the alphabet and how to write them.
