Letterschool Enabling Learning B.V. – an international edtech company focused on early childhood education, providing engaging digital tools to help children develop handwriting and literacy skills worldwide.

The goal was to create an intuitive and engaging application that helps young children learn how to read and write letters through play. The solution needed to support multiple languages — including left-to-right and right-to-left writing systems such as Arabic — while adapting to different learning speeds and educational needs. Ensuring a fun, motivating, and pedagogically effective experience for children aged 4–10 was key.

Building on an existing foundation, we took over the application and continued its evolution through new features and long-term support. The app was extended to cover a wide range of learning areas, including block and cursive letters, lowercase and uppercase writing, numbers, and spelling exercises.

Over the years, the application also underwent continuous technological modernization, including the gradual migration of the iOS codebase from Objective-C to Swift, ensuring maintainability and compatibility with modern platform standards while supporting the long-term evolution of the product.

We ensured consistent performance and scalability across platforms, while continuously improving the user experience to keep learning interactive, engaging, and accessible for children across different languages and regions.
