Thank you for the feature request. Unfortunately, I'm not sure I understand the request. iOS does not allow you to select different default apps. Apple simply makes their apps the default for browser, email, etc. On all other platforms, when you tap the URL link in mSecure, you can either launch our built-in browser or your device's default browser or app. If this is for iOS, can you provide me an example of an app that allows you to launch a link and have the option of which app to use to open the link with?
