Though its interface is a bit tricky, Stitcher connects you with just about every podcast out there. Podcasts are organized by subject, or you can just search for a familiar title. Shows can, in turn, be organized into playlists for a continuous stream. Once you've exhausted all your favorites, let Stitcher recommend something new. With a special emphasis on sources like NPR, CNN, and ESPN, Stitcher has a little bit of everything.
Tasker is a glorious application if you have the patience to learn how to use the app. What it does is allow users to create custom made commands and then use them in various places. There are many apps out there that have Tasker support and you can even use Tasker to create very complex commands for NFC tags. It’s difficult to truly explain what this app can do because it can do so many things. Between the apps supported, plugins you an add, and the sheer volume of stuff that you can do, there aren’t many apps out there as useful as this one. IFTTT is another excellent automation app. In some cases, it may even be better than Tasker thanks to its simplicity and wide range of uses. Droid Apps

With an accompanying set of useful widgets, it's the best weather app on Android. Droid App
