I remember this app as well; “Flipreader” comes to mind but yields no Google results.

It was the peak of RSS for me, beautiful UX, customizable, all the posts in sequential order if I wanted instead of algorithms…

I remember it because useless when web publishers realized they were losing ad views to apps like these and all the posts became previews with links.

I believe you are thinking of Flipboard (still around, but a bit different nowadays).

I think you are referring to Flipboard, it is still in the AppStore

Can't edit my post but it wasn't Flipboard.

Found it - it was Instapaper!

EDIT: Well maybe not, this one seems more like a replacement for ReadLater/GetPocket whereas the one I used was purely based off RSS feeds. I used it on the original iPad 1st gen so it's probably long gone. I give up.

A fun evolution would be to format it into a newspaper format, complete with headlines, front page, and "continue reading on page N", then print it out on large paper, fold it, and mail it to you.

There's probably no money in it, but a physical weekly customized RSS feed highlights newspaper would be neat.
