Smart TV App Development

The television has returned to its place as the undisputed heart of the home.
Modern Smart TVs are no longer just displays; they are sophisticated, internet-connected ecosystems that offer content providers a direct line to the global living room.

FX Digital is a specialist agency with deep expertise in navigating the fragmented Smart TV landscape. We help leading media brands navigate the complexities of multiple operating systems to deliver seamless, “lean-back” viewing experiences. From initial product strategy to design, high-performance development, and rigorous platform certification, we manage the entire lifecycle of your application.

Whether you are looking to launch a new VOD service or migrate a legacy application to a modern, scalable architecture, our team has the technical regional knowledge to ensure your brand stands out on the big screen.

Why Smart TV app development matters

The Smart TV market has seen explosive growth, becoming the primary gateway for digital entertainment.

• Global Ubiquity: By 2026, over 1.1 billion households worldwide are projected to own a Smart TV, representing more than 50% of all global households (Strategy Analytics).
• Shift to OTT: As consumers move away from traditional cable, over 72% now prefer Smart TVs for their integrated streaming apps and intuitive discovery features.
• High-Value Engagement: Smart TV audiences are “lean-back” viewers who spend significant time engaged with premium content. This environment demands a polished UI that rewards ease of use and high-quality playback.
• The Dominant Screen: Roughly 61% of internet households now use their Smart TV as their primary streaming device (Parks Associates).
• Ecosystem Integration: Modern TVs are now part of the wider smart home. Brands that secure a presence here benefit from features like AI-powered recommendations and voice-controlled navigation.

Key Platforms

What We Deliver

• Web-Based & Native Excellence: Where possible, we utilise a robust web-application approach (JavaScript/HTML5) to allow for a single codebase across multiple platforms, accelerating your roadmap. For high-performance needs, we build natively to unlock the full power of the hardware.
• The “10-Foot” Experience: Smart TV design is a unique discipline. Our UI/UX designers specialise in “10-foot UI,” ensuring layouts are legible from across a room and navigation is optimised for a D-pad remote, not a touchscreen.
• Custom Video Players: We build and integrate high-performance video players tailored to your content. We manage the complexities of multi-DRM (Widevine, PlayReady, FairPlay) and implement essential viewer features including multi-language subtitles, alternative audio tracks, and playback analytics.
• Strategic QA & Automation: Our dedicated QA lab tests across a vast range of real-world devices and fragmented OS versions. We utilise test automation to reduce regression time and leverage our deep platform expertise to navigate the complex manufacturer certification process, ensuring your application successfully reaches the app store.

Challenges & Considerations

Smart TV development requires solving for hardware fragmentation and strict performance requirements.

• Platform Fragmentation: Because Tizen, webOS, and Android TV, and other key platforms each require specific technical approaches, our team guides you in selecting the ideal development strategy. We analyse the trade-offs between native, cross-platform, and hybrid models to ensure we balance your budget requirements with the high performance your users expect.
• Remote & Voice Logic: Unlike mobile, every interaction on a TV is filtered through a remote. We focus heavily on focus-management and intuitive “up-down-left-right” logic to prevent user frustration. Furthermore, we build for the growing demand for voice control to allow users to search for content, control playback, and launch apps using natural language commands.
• Hardware Lifecycle: Consumers keep TVs for 5-10 years. We optimise our applications to run smoothly on the latest models while remaining performant on older, less powerful hardware still in active use.
• App Store Certification: Each manufacturer has a distinct, often opaque, approval process. Our long-standing relationships with vendors allow us to navigate these hurdles efficiently.

Our Work

BritBox: Global Expansion via High-Performance Architecture 

FX Digital partnered with BritBox to scale their streaming service across a fragmented global ecosystem. To ensure a premium experience on both high-end TVs and lower-powered hardware, we utilised the LightningJS framework, leveraging GPU-accelerated rendering to maintain smooth navigation. Our team managed the end-to-end delivery, including custom UI design and multi-DRM integration, enabling BritBox to launch successfully across Samsung, LG, and Vizio platforms.

Dyn Media: Redefining Sports Streaming on the Big Screen 

For the launch of Germany’s “home of sports,” FX Digital developed the Dyn Smart TV application across Samsung Tizen, LG webOS, Android TV, and Apple tvOS. To meet a fixed, season-opening launch date, we utilised a single-codebase approach with LightningJS for the initial multi-platform rollout, subsequently delivering a native tvOS application in Swift to leverage the full performance of the Apple ecosystem. The solution featured a unified user interface, complex third-party CMS integrations, and an interactive video player, delivering a seamless experience to fans across the DACH region.

Get Started

With Smart TV penetration reaching over 50% of households globally in 2026, the living room is your most valuable digital real estate.

If you need a partner who understands the nuances of the 10-foot UI, the complexities of DRM, and the roadmap to a successful launch across all major TV brands, we are ready to help.
