Some popular smart TV apps include the AccuWeather app, Pandora, NBA Game Time, YouTube and HBO Go, as of 2015. Hulu Plus and Netflix are also popular apps.
The AccuWeather app available on smart TVs gives users immediate access to weather forecasts for over 2 million locations around the world. The app features five-day forecasts that are available in 12 different languages, and it also gives alerts for severe weather in the local area and/or travel destinations.
The Pandora app on smart TVs offers high-quality music and a huge selection of stations. NBA Game Time is an app for those who love NBA basketball; the app delivers live updates of scores, highlights of previous games in HD and news from around the league. While the NBA app is free, it comes with a League Pass option -- for a fee -- that allows users to watch most regular season games live.
The HBO Go smart TV app allows the user to stream HBO movies and shows right to the television, while the Hulu Plus app offers the streaming of recently-aired network television shows. Netflix, arguably the most popular smart TV app, features an immense TV and movie catalog that can also be streamed to the TV.
