Video Streaming App Development Company: OTT & Streaming App Development

Updated September 2026 · Written and maintained by the Progression Agency strategy team

Progression Agency builds video and audio streaming apps for media companies, creators, fitness and education brands: on-demand libraries, live streaming, subscriptions and apps for phones, tablets and connected TVs. Video streaming application development is mostly decided before any screen is designed: how video is encoded and delivered, how viewers sign in and pay, and which devices must be supported on day one.

What is video streaming app development?

Video streaming app development is designing and building apps that deliver video content on demand or live to viewers across devices.

Streaming is used well beyond media: fitness classes, courses, church services and events all run on the same pipeline; see fitness app development and education software development.

What changes for live streaming

Live streaming app development differs from on-demand video because latency, chat and moderation matter while the stream is running. A live streaming app development company should explain how video is ingested, transcoded and delivered to many viewers at once, and what happens if a stream drops. Live streaming app development also covers features like reactions, gifts, scheduled events and recordings available afterward, which can be added once the core stream is stable.

Live streaming website or app: which to launch first

The website is often the quicker first release, because viewers install nothing and the same player can sit behind a paywall or member login. It suits conferences, worship services, classes and one-off events where the audience arrives from an email or a shared link.

Apps earn their cost later, when viewers come back often enough to want notifications, downloads or a TV screen. We usually build the video pipeline and entitlements once, so the website and the apps read from one library and one set of accounts. Browsers add limits worth planning for, such as autoplay rules, and we test those on real devices before an event goes public.

Security, privacy and store rules for video streaming apps

Streaming apps handle licensed content and payments.

• Content licensing and DRM obligations.
• App store rules for digital subscriptions.
• Accessibility: captions and audio descriptions.
• Privacy laws for viewing data.

Our video streaming app development process

We validate the video streaming concept and target users, define a first release around the core loop, prototype and test the flows, build cross-platform or native in two-week sprints, prepare App Store and Google Play submissions, and launch with analytics and acquisition campaigns. A live streaming mobile app gets an extra stage in that plan: rehearsal broadcasts on phones under poor network conditions, including drops and reconnects, before any public event.

How much does it cost to build a video streaming app?

As a price band, a video-on-demand app on a managed video platform commonly costs $100,000-$180,000 and a multi-device streaming platform with live and TV apps $180,000-$300,000+. Streaming delivery is an ongoing cost.

Technology for video streaming apps

Chosen for speed to both stores and long-term maintainability. Video streaming web hosting from a packaged provider can hold a small library at the start, but your own player, entitlement rules and control over how delivery splits across regions all call for custom work.

Mistakes to avoid when building a video streaming app

What sinks apps in this category.

• Building an encoding pipeline from scratch unnecessarily.
• Ignoring TV platforms.
• No captions.
• Underestimating delivery costs.
• Weak search and recommendations.
• No offline mode.
