While there are many desktop and mobile RSS readers, there are only a few which allow one to start reading on the desktop and continue on your smartphone, with the read status of articles being propagated in both directions.
YomoMedia is one such client, and unlike the competition is actually free too. The software can handle the usual RSS feeds, but also audio and video podcasts too.
The mobile client features an especially attractive user interface, and high-lights a particular feature of the software – the ability to bundle similar feeds into specific categories to view together.
