On a standard web browser it's very easy to see how your data is being transferred to servers via the padlock icon and tools like Firebug or Chrome dev can give you the information for things like AJAX requests.
With phone/tablet apps, it's a different matter and is pretty difficult to find out if your data is being transmitted across secure connections or not without digging into network activity.
I was wondering if there are any standards built-in to dev kits about displaying this information on apps as there are in browsers? Something official that can be relied on as opposed to custom icons on individual apps that don't really mean anything. Or do users simply not care that much about this information?
