We are a building a Smart time management and event discovery features into one single unified easy to use and intuitive application. we are using lots of custom-made react native components. we also implementing redux in the app. facebook login, some events are pulled from facebook... We delivered a beautifully designed iOS/Android app using React Native which allows for a shared codebase and rapid development/iteration cycles. We can also integrate it with back-end solutions like Firebase for quick development, or build a custom backend using Node.js and GraphQL to allow for more flexibility and scalability. I also made calculator ,counter ,animated fish app and many other app.
