Pretty well any RSS reader will do it. Do a search either for "RSS reader" or "News aggregator". If you are after a mobile app then Flipboard is pretty good, certainly available for iOS, probably for Android as well.
If you can program even a little bit then check out SimplePie - it's a PHP library - very easy to add to a web page (providing your hosting uses PHP)
