Multiple iOS apps knowing about each other

Hello,

Currently my compnay has put out several iOS apps and they are able to pass data between each other. I believe its a file that is stored in a common location. Is there any way for an app to know if another app (from the same developer) is installed? Our use case is to present a link to app store if the an additional app is not installed, or an "open in" link if the app is installed.


Thanks,

Joe

Have each app write to the common location a value indicating it is installed when it is first launched.
