tablet application

I'm looking for a software developer to create a tablet application for both iOS and Android devices, designed to be a learning tool. My vision for the app is to create an educational experience that is both enjoyable and informative. I prefer a bright, colorful, and vibrant design that will engage the user in an interactive way that captures their attention and encourages engagement. My ideal developer will be knowledgeable in how to create a tablet application that works on both iOS and Android, with full compatibility and functionality. Kids will interact with the app to learn, math, language arts and other social emotional skills. The application will be similar to https://www.smile-zemi.com/s/ to get an idea of the application we want to develop. Developers with similar experience will be preferred.
