Mobile app

I am looking to develop a mobile app for both iOS and Android platforms. Its primary function will be Live Score, so that users can keep track of a variety of scores in real time in any sport. It is important that the app is accessible to and enjoyable for people of all ages, from teenagers to young adults and beyond. It needs to be easy to use, with intuitive features to make it a great experience for the users. I’m looking for someone experienced in mobile app development who can help me create this app in an efficient and timely manner.
