What is a Live Streaming App?

A live stream is multi-media digital content broadcasted by one host and transmitted to many viewers over the Internet in real-time. It can feature live events, like sports, news, a security camera feed, or on-demand content, like TV and movies. Video streaming complements social, gaming, telehealth, remote learning, online dating, eCommerce, and virtual events use cases.

Facebook Live, TikTok, Twitch, and YouTube Live are some of the most popular live streaming platforms available to creators. But, developing a proprietary app to host your brand's live content allows for greater control over creating your user experience, monetizing your stream, and scaling on your terms.

While developing a custom live streaming app requires up-front financial and engineering resources, its benefits can prove invaluable to businesses looking to bypass existing platforms and create their own streaming experience.

  • Analytical Insights: Apps can analyze performance and engagement metrics of their live streams and leverage them to improve their broadcasting and content strategy.

  • Real-Time User Engagement: Native live streams push users back into your app and promote real-time engagement with your content and team.

  • Monetization Opportunities: Apps can financially benefit from hosting live streamed content by incorporating paid ads, offering premium subscriptions, asking for donations, and implementing a pay-per-view model.

  • Brand Humanization: Sharing a candid video of someone from your app's team is a powerful tool for your business. It creates great trust between your mobile app and its users when they know a real person is behind the screen. 

Common Live Streaming Concerns

Most viewers will exit a live stream within seconds if they experience technical difficulties. Your mobile app must be prepared to take on the common challenges while streaming. Here are the top three fro your developers to consider:

  1. High Latency: Your streaming protocol must be equipped to adapt based on the viewer's network conditions. High latency decreases communication bandwidth and impacts the quality and speed of your audio and video stream.

  2. Poor CDN Region: Slow clouds, regional outages, and CDN problems like stalling or buffering will interrupt UX and result in a loss of viewership. As a content distributor or video streaming service provider, you must ensure high-quality and seamless delivery.

  3. Cost: Your live stream project can add up quickly, with upfront costs to cover your tech stack, engineering compensation, design work, QA testing, and project management.

  4. Content Moderation: Malicious users can make your mobile app an off-topic and unsafe digital environment by streaming harmful content and posting it in the chat. To keep your live stream app a safe and inclusive place for all users, implementing a moderation solution is essential.

  5. Limited Scalability: If you want to scale globally while boosting customer satisfaction, your app will need to be capable of supporting a high number of active users while delivering an optimal UX. Server health, metrics, use, and monitoring of the bandwidth resources should be at top of mind when developing your app. 

How to Create a Live Streaming App

Now that you are familiar with the possible types, benefits, and concerns of live streaming apps, let's dive into how to build one of your own in six simple steps. 

Building your own app? Get early access to our Livestream or Video Calling API and launch in days!

1. Determine Your Audience

The purpose of a live stream app is to create and broadcast content for users---so it needs to appeal to them. Identifying your audience will help you decide what type of live stream app to develop, the features it should include, and narrow down monetization options. One way to do this is by collecting user feedback if your app is already live or holding focus groups if you're still in the early planning stages. 

2. Implement Monetization Strategies

You'll need to monetize your streams to make money off your app. Combining multiple monetization strategies is the most effective way to ensure that all your hard broadcasting work pays off. Here are a few methods you can mix and match: 

  • Paid App: Charge a fee to download your app.

  • Freemium: Offer a free app download but charge users for access to premium features and content.

  • Advertisements: Feature sponsored content during your live stream or add static advertisements to the UI of your app.

3. Solidify Your Tech Stack

Your engineers must choose a programming language, database, and other developmental elements in any app creation process. However, building an app with live stream capabilities will require their attention to a few other components of your tech stack:

Streaming Protocol:

A video streaming protocol standardizes segmenting a video stream into smaller chunks that are more easily transmitted. There are a few protocols commonly used to stream live video:

Streaming Platform:

You will need a streaming platform to help build a highly available architecture that delivers a reliable real-time viewing experience. Building your own live streaming from scratch with HLS can be simple, but if you're looking for a ready-made platform, Amazon Web Services (AWS) is available. AWS offers two live video streaming AWS Solutions to cost-effectively deliver media content to a global audience as part of the AWS Solutions Library.

  • Content Delivery Network (CDN): Choosing the right CDN ensures the availability and performance of the live stream for your app users. AWS CloudFront powers popular streaming services, such as Netflix AWS MediaLive.

Choosing the best option for the three tech stack components above comes down to knowing what streaming aspects are most important to your audience: speed, clarity, or adaptability. Start by defining the problems that you intend to solve and adjust your stack accordingly. 

4. Design An Intuitive UX

Once you have identified your target audience and their needs, you can design a custom UI/UX to meet them in your app. When it comes to live streaming, less is more---and video should be the hero element of your interface design. 

5. Build & Test Your Prototype

Your team might have dozens of ideas they'll want to implement in your live video streaming app, but the best way to put them to the test is by building a prototype of your app. A minimal viable product (MVP) is a lightweight version of your mobile app that only contains the essential features needed to function. It's simple and intends to help your team gather feedback from Beta users.

6. Release, Promote, & Iterate Your App

After you have completed steps one through five, your live stream app is ready to launch! You'll need to market your app in a way that sets it apart from competitors and ensure that users have an enjoyable experience after downloading. Then, you'll need to keep a close eye on performance metrics and the KPIs you've set for your app to understand user behavior better and tailor the UX to improve it. 

Cost of Creating a Live Stream App

Depending on the features you plan to include in your streaming app, it can become quite an expensive and time-consuming project. While the final price of creating your app will vary, be sure to estimate the cost of your streaming protocol, chat solution, video service, storage plan, CDN, engineering, design, and project management costs before getting started.
