Ive tried a few feed readers, and this is by far my favorite one. Ive used Feeddler Pro since its previous version (built for previous iOSs), and paid for this update without hesitation.
I like the clean new interface, and the way I can customize my feeds into folders. Its easy to see at a glance which feeds have new posts, making this app the first thing I check on my phone when I wake up (for an interesting article to coax me out of bed).
My only complaints are: 1) The option to switch between RSS and website view seems to be glitching, so that I must use the "Open in Safari" option to view a full website sometimes; and 2) The Evernote integration no longer saves the entire text of the article--it still lets you add tags and select a notebook, but only saves the URL in a new note now. My workaround is to open the article I want to save in Safari, and then use the EverWeb Web Clipper app to save the article to Evernote the way I want it.
