title: Is there a list of iOS apps that can be called using custom URLs?
body: <p>It is possible to launch your own app via custom URL scheme as described at <a href="http://iosdevelopertips.com/cocoa/launching-your-own-application-via-a-custom-url-scheme.html" rel="nofollow noreferrer">http://iosdevelopertips.com/cocoa/launching-your-own-application-via-a-custom-url-scheme.html</a> for example. Is there a list of the apps that use this mechanism somewhere already? A list of custom URLs available to date? If you have or know an app that uses this mechanism, adding it here will also help.</p>
