Puse News Reader is an iOS app that uses RSS feeds to creates a visually engaging interface for browsing the latest stories from your favorite sites. In addition to the headline, the app pulls in the first paragraph as well as the banner image (if tagged correctly). Clicking on a story open up the article within the Pulse app (usually without the ads since it is still pulling from the RSS data). If you still need more details, you can click a button to open the story in the full web page mode. I find this method much faster for browsing stories because you can quickly scan through the headlines to see what is of interest, and the pictures are good at visually reminding you what you may have already read elsewhere.
You can easily add your favorite RSS feeds by searching for them or adding the URL directly, or if you use Google Reader, you can just login with your account.
I've tried other RSS readers, but they often felt too much like work. I was never able to get into a good rhythm where I would consistently "mark" the stories I had already read, or browsing between sources or for most recent stories was never as efficient as I would have liked. Navigating in Pulse is very intuitive and "iOS" friendly, making good use of the swipe for scrolling the headlines and tabs across the top make it easy to organize your feeds. I've also found Pulse to be quite versatile. I use it to read tech sites, deal sites (a bad habit I just can't kick), and some of my favorite Twitter feeds. Having all that organized in one app makes it much faster to get in, see what's new or of interest, and then get out.
My only complaint is that there isn't a way to go back to get "older stories". Once you hit the end of the line, you're done. On a few instances, I saw something interesting I wanted to read in the morning, but when I went back to read it that night, it had already "rolled off" the page, so I'd have to go to the website directly to find the article again. However, Pulse News does let you tweet or facebook post stories that you find, as well as email or "InstaPaper" articles as well, so there are ways to tag items you want to save for later.
The app is currently free in the Apple Store (I was one of the suckers that actually bought it early when it was released), so it's worth checking out.
