2020 has become a year of video conferencing. Apps like Zoom and MS Teams had dominated the market. Google Hangouts introduced free-of-charge features, and Discord had seen an increase in daily active users. The reason is the Covid-19 pandemic that put the world into lockdowns and social distancing. People needed to keep socializing and working, and the abovementioned solutions have become an alternative to real-life communication.

Video conferencing app statistics 2021

2021 has inherited the last year's demand for web video conferencing software. The companies like Microsoft, Apple, Dropbox, and Google introduce either remote or hybrid work modes. People adopted new ways of communication. Companies, at the same time, reshaped their strategies with heavy use of digital technologies.

Numerous research stated that online communication affects lots of small businesses as well. They need to adapt to new norms and invest more in digital communication as a core way of interacting with clients.

The question that may spring into your mind is, "Do I need to start digital disruption in my company too and switch to online communication?". Our answer is yes. Business communication software can benefit your business in employee efficiency, client engagement, and appeal to larger audiences.

Let us guide you through the emerging trends in video communication, vital features, and success stories. Let's take a closer look.

Why Video Conferencing Software has become so crucial

The recent Gartner report forecasts the worldwide social software and collaboration market growth to total $4.5 billion in 2021, an increase of 17.1% from 2020. Moreover, Gartner predicts that by 2025, nearly 65% of application software providers will have included different renditions of social software and collaboration functionality in their portfolios.

This data clearly shows how online communication undergoes massive change. People discover new ways of socializing, companies seeking ways to provide an offline-like experience using digital technologies and introduce new tech opportunities to their clients.

For example, the workplaces today hardly resemble the same ones during pre-pandemic times. The recent crowdsourcing session by Deloitte on workplace strategy, virtual collaboration, and workforce reskilling found that:

  • Organizations were not as ready as they thought for the virtual workplace;
  • Companies should redefine their use of collaboration tools to pioneer a new way of working;
  • Managers were unprepared to support the culture of the team and the overall system.

These problems dramatically reflected on such activities as organic collaboration, innovation, strategy sessions, and relationship building. But now, things start changing: companies deploy security infrastructure for remote workers, conduct workshops online, and organize virtual team buildings via Zoom.

Business executives also say they are planning to stick to a hybrid model of work. This model considers employees spending three days in the office and the remaining two days working from home. According to Buffer Remote Work Report, 99% of respondents prefer to keep working remotely.

As for business, the same applies to new strategies of operating and improving customer engagement. Those will require cloud technologies, including video meetings. CEO's plan to increase investments in their long-term digital transformation by more than 10%. Clients value new opportunities for remote interaction that saves time and helps to keep the safety measures.

The benefits of developing custom video conferencing software

The adoption of video meeting software has become crucial for multiple companies. To keep the efficiency of the business, you should consider developing custom communication tools. The solution will keep you connected with your employees, clients and help you stay relevant in a current business environment. Here's the list of key benefits you get:

Seamless remote work environment

As 63% of high-growth companies introduced hybrid work mode, the remote communication issues stand up first. Usually, employees need video calls, messaging, document exchange, and external tools integration for efficient work. Most modern solutions include these essential features.

Trends in remote work growth

Remote client interaction

The pandemic ensured that including digital communication helps build better relationships in terms of client interaction. Even before the pandemic, 96% of customers Forbes surveyed claimed excellent service as a determining factor in loyalty to a brand.

Remote interaction saves time, allows finding out more aspects of the service clients get, and even provides closing deals. These points can potentially make your customers more loyal to your brand.

White label software

Some companies cannot use software like Slack or Zoom due to privacy and security concerns. They also prefer not to advertise any external services they use. White label solutions don't have any logos, watermarks, and advertisements while you have a call or streaming. Security concerns are also covered.


It is vital to have your data stored and transferred securely. Due to lots of data leaks, legislation, and regulations, your software must comply with the local security requirements. To achieve that, you have to pay attention to implementing P2P protocols, using reliable cloud/server providers, and researching local regulations. By implementing all the steps mentioned above, your app is unlikely to face any data breach.

In-app in integration

However secure your video conference solution is, you have to keep in mind that you need external integrations. For example, your app may require payment and messenger integration. With custom software, you can build a video conferencing app into your existing software.

Multiple features for social interaction

Remote work revealed multiple problems people face while working at home. For example, they lack socializing with colleagues, coffee breaks, and small talks during the day. Empower your video conferencing app with 24/7 available rooms, where your employees can play simple games or have discussions with an office kitchen background.

Types of video conferencing applications

Before kicking off a development process, define the type of your application. You can interview business analysts to find out what business activities require a video collaboration app.

As an experienced team of developers, we highlighted the key types of video calling applications our clients need:

Video Conferencing

Most clients seek an app that provides video conferencing, messaging features, and screen recordings. Additionally, some of them have external integrations for appointment management.

These apps don't require many resources as they adjust to users' device and internet capabilities. They usually support up to 50 conference members simultaneously.

The well-known examples of video conferencing apps are Skype, Google Hangouts, and Zoom. The latter has become extremely popular due to its simplicity and no requirement to be a part of the Microsoft or Google ecosystem.


Messengers like Facebook, Telegram, WhatsApp, and Apple's Facetime/iMessage have a video chat feature. Except for quick message exchange, they provide opportunities for video chats. Some of the messengers allow holding calls typically for 2-30 people. Some messengers apply AR/VR technologies to enable users to use custom masks and animations.

Fast Video conferencing app development

Online collaboration software

Video conferencing is not the only option companies seeking for remote collaboration. They require proper connectivity covering all the corporate needs. For example, an app like Slack allows messaging, video and audio calls, sharing documents, external tools integration like Jira & Google Calendar, and group channels.

There are plenty of solutions on the market that provide the same functionality as Microsoft Teams and G-Suite. Still, they are built differently.

Unfortunately, companies seeking privacy avoid using these tools. They may be affected by hacker attacks, use wrong security protocols, and are not suitable for internal work ecosystem integration.

Entertainment apps

Video chats are not only applicable for work but leisure as well. Having fun with friends or playing video games together has become standard with apps like Discord. Those apps allow playing games like Pictionary or Apples to Apples, arrange video conferences, stream favorite games, and have a group & private chats.

How to Create a Video Chat App?

All apps, as mentioned above, might work for the IT or creative industries. However, telemedicine, real estate, banking, insurance, events & exhibitions industries require deeper integration with local IT infrastructure.

Hiring a team of software developers would be an option for creating a custom app. The main advantage is that you can design your application with compulsory features, built-in integrations, and levels of accessibility. Moreover, hiring a team means they could adapt to your security requirements as well.

So, how to build your own video conference system with a team of professionals? Here are the critical steps for creating your video-based software:

Define the requirements

Firstly, you need to understand the target audience. Secondly, consider all the possible use cases of your application. Make a list of them so the team gets a better understanding of your requirements.

Select the team

This point includes searching and hiring either an in-house team or finding an outsourcing company. Usually, outsourcing teams are easier to hire and do onboarding. They already have expertise in particular industries, a team of developers, hiring managers, and customizable engines. All those means you'll get a faster delivery compared to hiring a whole in-house team.

You should also consider that you need to hire about 10-12 specialists for an in-house team. When the development process is complete, you'll need to leave only 5-6 specialists for QA and additional features development.

Get a proof of concept (POC) or MVP

This point is crucial when you have no clear vision of what your product or service should have. Companies tend to use PoC and MVP for collecting feedback, checking hypotheses, and testing the business model.

PoC and MVP include developing a prototype by a team of UI/UX specialists to provide the design for your app. It also allows you to evaluate potential use cases and the usability of the app. A team of business analysts would help you uncover more opportunities you could use.

MVP and PoC stages in app development

When you find a perfect match with design, a team of video conferencing software developers and engineers will develop technical requirements and an application with basic features to get it tested.

Usually, PoC and MVP stages take about 4-10 weeks and cost from $10,000.

Get to know your team

The team of video conferencing app developers comprises various specialists. Each of them is responsible for different aspects of the application:

Backend developers

Backend developers are responsible for building server logic, implementing video and security protocols, and connecting all the required APIs. The latter is used for external software integrations like payment gateways or cloud services.

Frontend developers

Frontend developers are responsible for building the final look of your video meeting application. They get all the design and mockups and implement them as separate working elements in your app.

UI/UX designers

As we previously mentioned, designers are responsible for how your app will look like. The design mockups and transfer them to a team of frontend developers.

QA specialists

The quality assurance team provides manual testing of your application. In case QA specialists find any bugs, they'll notify developers to fix them instantly. QA allows you to avoid critical issues before the release and quickly resolve any if they appear after the launch.

Project manager

Project managers are the key people you will communicate with. They are responsible for meeting deadlines and managing developers. They can also provide you with updates and offers that could make your project better.


DevOps engineers put together all the pieces that make up a project. They know the specifics of programmers, testers, system administrators and help to simplify their work.

Solution Architect

Solution architects provide all the team with the technical documentation, standards, and workflows for creating a unified product.

Choose the tech stack

Here is the list of standard technologies our team uses for video calling app development:


  • React Native
  • Saga
  • Redux
  • Swift
  • Kotlin
