Not only can an Android app register that it handles links for a given domain or scheme, but multiple apps can be available, if say, you've written a better imgur or flickr viewer. But the UX to say "always open this type of link in this app" is simple and unobtrusive as well.
Shame iOS hasn't yet followed along with this, but I suspect it might be one of those things that would substantially affect legacy iOS apps.
I am not familiar with iOS but in Android they do, since day one, how is iOS different in that regard?
Opener attempts to fix this by mapping web links to app-specific links.
It's more hassle to implement but a free with iAP is surely a better monetisation model for a 'utility' app like this?
