Free Android Apps

As an open source operating system, Android is great in that you can find many of the apps you need for free (though keep in mind, Android apps are way more hack-able and track-able than iOS).  A great source for free apps is the Amazon Android App Store.  In addition, every day there is a free app available for download normally is a paid app.  These aren't all duds like Turbo Grannies - Angry Birds Rio and Plants vs. Zombies both have been featured free apps.
