Major Factors to Consider Before Starting with a Smart TV App

Understanding the Market

First of all, you need to analyze the TV platform options available in the market. Learn about their target audience, popularity rates, current trends within platforms, etc. Do proper research on the market to get the app idea you want to develop. Further, see your competition and the reception rates of similar applications through each platform.

Size of Screen

The size of the screen is a critical factor while developing a TV app. It affects text readability, colors, resizing, horizontal alignment, and other factors that reflect how well you can predict and adapt to different screen sizes. It is recommended to ensure that the app can be resized if used on a small screen as well. One should always use proper padding between the core visual elements;

Remote Control & Navigation

A big difference between navigating a regular app and a smart TV app is the variety of tools that users can navigate their smart TVs with. These tools include common remote controls, digital assistance, smartphones, and gamepads. The selection of navigation tools usually depends on the smart TV platform and so you should consider it when designing the app for offering a seamless experience.

Smart Recommendation Features

The smart recommendations in the smart TV apps will assist in tracking browsing activities, search histories, and user preferences that aid in suggesting the appropriate content for viewers. The TV apps’ intelligent recommendations contribute to a better user experience and more time spent on the platform. Users will then receive content for OTT platforms that focus on entertainment, for example, based on their browsing patterns and preferences.

Testing on Real Devices

It is always beneficial to test smart TV apps on real smart TVs. This will help you to ensure the app functions as intended. Otherwise, users may encounter unexpected bugs that will further have an impact on the user experience. Also, if you don’t have an opportunity to test all features on a real device, it is always preferred to test features that are on the highest priority, such as video streaming, and custom navigation.

The Bottomline

Streaming content on Smart TVs is a new form of entertainment that strives for a user-friendly and convenient experience. It is now even considered a robust platform for developing a wide range of digital products, from Smart TV streaming apps to learning programs.
