Hi,
I've gone back and forth on an app. It'd be nice to have, but haven't been sure it's worth the effort and cost, not just to get developed but also maintain over time.
I think around the time we were seriously considering it, we'd also hit a bunch of hurdles with Apple blocking AppShopper and TouchArcade app updates, so it left us with a bad taste in our mouths.
Besides that, I'd also hoped Apple would extend web push notifications to mobile Safari, but they still haven't done that.
Right now, we don't have any serious plans on doing an app. I don't know if that will change.
