To change this behavior, long-press the link and choose either “Open” (to open in the browser) or “Open in ‘Library’” (to open in the app). On iOS, universal links open in the app by default if the Gospel Library app is installed. Users can choose if they want links to Church content to open in the Gospel Library app or in the browser. The user or the operating system decides whether to open the content in the web browser or in the app. Links that are set up to work in both a browser and an app are called “universal links” on iOS or “app links” on Android. With the introduction of Gospel Library Online and continuing improvements to mobile operating systems, users can open Gospel Library content in the browser or in the Gospel Library app using the same URLs. Linking to specific content in an app or website (instead of the home page) is called deep linking.
