I first saw the mention of a SR Iphone app in someone's signature. As an Android user, I searched the PlayStore for apps, and downloaded it there.
I love the app. Much faster and more responsive than the browser on my phone. That's a good thing for a couple of reasons. Makes SR more easily accessible, easy to track which threads I have read, and if I need a quick reminder or attitude adjustment, the site is "right there."
Even when I'm on my computer, I check in on the app instead, simply because the interface is so slick and the responsiveness so quick.
