App Links is an open, cross-platform solution for app to app linking. App Links provide all the tools you need to expose deep links in your app or to have your app link out to others in the ecosystem.
For example, if someone is in the Mailbox app on their phone and sees an email containing a link to Pinterest, it will direct them into the Pinterest board in the Pinterest app on their phone. If they don't have Pinterest downloaded, it will present the person with the option to download the app from the App Store, or they can view the Pin on mobile web.
Right now, linking on mobile is a lot more frustrating and complicated than it is on the web. There isn’t an easy, consistent way to control what happens when someone clicks on your content in mobile, which makes it difficult to provide the best experience for your users. It’s also hard to find out when—and how—to send people out of your app and directly into another.
We strive for App Links to work side-by-side with other standards and libraries, because we know that app developers do not want to be in an either-or situation. Our approach enables people to share and discover links in a common and cross-platform way. While many companies are working to solve the problem of deep-linking in native apps, we are trying to build a truly cross-platform solution that addresses linking on mobile for iOS, Android, Windows, and web.
