Hairy Letters is an award-winning educational app developed by Nessy Learning Limited. This app aims to teach children aged 4 to 6 the names and sounds of each letter in a fun and interactive way. The app offers six color-coded stages to introduce letters, and each stage has its own set of games and activities.

The app's standout feature is its multisensory learning approach, which includes tracing letter shapes on the screen with a finger, playing games to build letters into simple words, and animated characters that bring letter sounds to life. Additionally, the app helps children learn to blend sounds into words and includes upper case letter names.

Overall, Hairy Letters is a great tool for parents and teachers looking to help young children develop their language skills. The app is entirely free of advertisements and in-app purchases, making it a safe and reliable option for young learners. The app is available for iPhone and exclusively uses British English.
