About a week after they released their Nick app, Nickelodeon has now released a Nick Jr. app for all Amazon Fire TVs, Fire TV Sticks, and Fire TV Edition televisions. This new Nick Jr. app is tailored for kids under 6 years old, while the Nick app is for older kids. As you’d expect, the two apps are very similar in their design and features, so take a look at my overview of the Nick app to get a feel for both apps. To access all of the content in either app you’ll need to activate the apps with a subscription television provider, but both apps do have a decent assortment of free ad-supported content that does not require activation to view. The free content does include full-length episodes of most of the shows available through these apps.
