Warning, shameless plug incoming. I made a HN app for iPhone and iPad to solve some of the issues of the site. Mainly going back and forth from comments to article. Haven't gotten to a better voting yet, but I may in the future.
I suspect it's not, as mine is universal. If you had mine on it, they'd both have the same icon. Also, you can go to the app store from the link above and if it says "Open" it means you have it on the device.
