“Apps intended for kids may not include third-party advertising or analytics.”

Whether you are a first time developer or a large team of experienced programmers, we are excited that you are creating apps for the App Store and want to help you understand our guidelines so you can be confident your app will get through the review process quickly. The guiding principle of the App Store is simple – we want to provide a safe experience for users to get apps and a great opportunity for all developers to be successful. If the App Store model and guidelines are not best for your app or business idea that’s okay, we provide Safari for a great web experience too.
