Good Android applications include Math Training for Kids, Facebook Messenger, Twitter Periscope, Netflix and Hulu Plus. Some of these apps are free, while others require purchase or a subscription.
Netflix and Hulu Plus have both adapted their streaming services to be used on Android devices. The apps themselves are free, but the usual Netflix and Hulu subscription fees apply. Google Chromecast enables users to stream Netflix shows from their Androids to their TVs.
Facebook and Twitter apps are also available to Android users, with Facebook Messenger and Twitter Periscope completely free of charge. The educational Math Training for Kids app is also free.
