# Getting Started **Why React Native ?** We love building apps with React Native, because it helps us create high quality products for both major mobile platforms quickly and cost-effectively. React Native is a framework for cross-platform mobile app development for iOS and Android. If you want to save time, money, and staff resources significantly, then React Native is the ideal business solution. This progressive technology provides traditional and modern methods of hybrid mobile app development. For several years of work, the framework was used in world-famous apps such as Skype, Instagram, Airbnb, Walmart, SoundCloud Pulse, UberEats, Tesla, Tencent QQ, Baidu Mobile, and many others. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
