One of my most used services would be Feedly, which has been updated today with a bunch of additions. First, we have the usual speed improvements, a new 'discover' section, and support for Samsung's Galaxy Gear smartwatch.
Feedly for Android has seemingly been ripped apart and put together again, with a nice spring clean. Feedly says that its Android application has close to 300% faster start times, and a more fluid scrolling experience. Some visual changes have made the cut, with fonts being re-tooled for easier readability. One of the problems that people had with Feedly - where it auto-refreshed when switching back to the app - has been fixed.
The updated RSS reader has also received a new "discover" feature, which sees the day's most popular stories featured. New Facebook SDK integration and support for Samsung's Galaxy Gear has been implemented, too. You can grab the latest version of Feedly for Android from the Google Play Store.
