Linking to external web page
I'm creating an app and need one of the links to direct to an external website (our online shop). Ideally I'd like it to open the page in the phone's default browser but can't seem to do that.
I've managed to display the site within an iframe but the site is too big to view on a mobile device and I'm told it's not possible for the user to 'pinch' the page to zoom in or out.
What would be my option to link users to the external page from the app?
Thanks!
