1. End-to-end Market Research “An Overall Market Review”

Well, it’s not the case only with video chat app development where the market research is needed. But, this is the first foremost step or can say a key investment any business needs to make before getting into the market for a stable and smooth growth.

This is a process where you can get to know about your target audience’s mind – their pain, thoughts with demands and requirements. This research will also get you more understanding of your competitor’s approach – their niches and more, to make an ultimate solution by building a better version of your video conferencing app.

2. Go for Appropriate Developers Team Hiring “The Foundation”

After performing a complete market survey, the next step to take is – checkout for the best developers team. Yes! the perfect team that can work through all your thick and thin to get your video conferencing app into reality.

However, if you already have a set of proficient developers to work on then you can relax and proceed further or else, you have to opt for the developers as a full-time employee, and have to have keen eye on the hiring process to select the skillful dedicated one. Of course, the full time employee hiring concept can reduce the most from your overall infrastructure cost, which is very important for any business to look out for.

3. Set MVP features “Time to Make Decision with Investment”

MVP (The Minimum Viable Product) is something which plays a key role here in the entire app development process. It’s the one which makes you understand the core step that is required to make an appropriate approach to get connected with your targeted audience. Well, MVP speaks about actual products with the most viable and valid functions. It supports you in analyzing a variety of concepts that are related to market launch, in such a way that exposes you to make a decision whether you have to continue investing in the product development or not, for better future stability.

4. Final Testing & Market Launch “Final Market Approach”

This is the final common step for every product that comes across its journey from development to market launch. This is to make the business aware of what could be the final outcome when the app reaches the market, so that they can rectify the issues if any at the first stage.

However, the testing is based on several ways that includes survey, end users review, and more. The core point is about having a better clarity about the product with its usage, features, compatibility and adaptability. These collective feedbacks result in further enhancement of the application. Once done with all these processes, the final approach of market launch is executed where the video conferencing app gets connected to the users and generates revenue.

Now, you must have got a better idea about the key measures that you need to take care of before developing an app, at the constructive level. Thus, let’s proceed further with more and understand this version much more clearly.

Thinking Of Creating Your Own Video Conferencing App?

Explore the Steps to Build a Video Conferencing App

Now, let’s have some discussion on the logical part that must be considered while building a video conference app for your business. This is based on elaborating the features and requirements identified in the Pre-stage phase.

The three common strategies for building a video conferencing application are:

  1. Communication Platform as a Service (CPaaS)
  2. Branded Software Development
  3. Prebuilt Solutions

The last strategy, namely prebuilt solutions are the most recommended strategy to create a video conference app for your business.

Step 1: Study Your End-User  

This initial step will identify the type of users on your video conferencing app. Such insight can be drawn from a survey which expects more ‘visual expressions’ on the app by including more filters, stickers and emojis. 

The design process tends towards digital product security and will be a value addition for the end user. Privacy is a significant factor and will be based on cyber security, supportive security features and encryption for quality excellence.

Step 2: Determine the Key Features of your App  

The typical user experience is what defines this feature. Let’s have a look at some of the core features that are needed for a video chat app development,

video conferencing app features

New User RegistrationIt is the first screen which defines the user experience. It will provide information about the critical field, phone numbers and email address. It will integrate with major media networks like Gmail, Twitter and Facebook.

User’s Profile Management – A core function, it will show the general profile details of the user and brief reference to the location of the user in the bio. Here, you can see the phone number and picture with all the privacy settings being established.

Search & Add User’s Contacts – The app must be able to scan contacts and connections using two features – search engine, that aids easy navigation and a quick identification of correct references with real name or username, incorporating with the user’s phonebook contacts.

Users Overall StatusThis feature indicates the current status of a user that includes idle, away, busy, and more. Even it indicates the current online presence as well as the last logged-in time of the user.

User’s Interactive Chat A video calling app without the ability of text messages is something unimaginable. Yes! This is one among the most needed features every user must be looking out for. Moreover, text communication is always considered to be the most important and proven solution at the workplace for maintaining effective communication with clients.

Video/Audio CallsVideo chats and calls are the core feature for any video conferencing apps as they are supportive to connect the people as well as the businesses despite their geographical location. Since, the feature regulated the phone calls it is much appreciated on the whole. Yes, it makes the call more affordable when made to any foreign land.

Group Video CallsForming and engaging with like-minded people over a social community, is the best part of a video calling application. Within these communities, the people can have both casual as well as formal video chat regarding any topic they like, games, jobs, assignments, politics, and more.

Therefore, it is always good to have a check on the strength of users, the video conferencing app can have. However, this simple evaluation can make a big difference in business where you have to involve a certain count of business people to have a further business with. But, at the time keep in mind that as the group increases the estimated cost of an app will also increase.

End-to-end Encryption – For any conversation, the security is a major issue to be pointed out. When it comes to the encryption process, it starts with the sender’s end and gets over at the recipient’s end, where with in-between, it’s all about protecting the data from the hackers – where nobody can be able to read the content of the message unless it reaches the recipient.

Immediate Push NotificationsWhile developing an app, you have to see whether the app is able to provide the notification on your device or not. As this feature will retain and also remind the users of the app again and again, at the same time also notify the users about important updates or chats. 

This push notification works regardless of the fact that whether the user is on the call or not, it will simply pop up the message via the phone’s notification bar.

Entire Screen Sharing – Enables the users to share their entire screen with other participants during any video calling session making the session a solid collaboration. Here, with screen sharing if needed the participants can also share the emojis and other reactions to make the presentation more meaningful. Overall, this feature eventually boosts up the user experience with more interactive and effective communication.

The above are some of the essential features but there are more to dive in, the other add-on features include virtual background, Stickers, masks, voice-enabled assistants, offline contacts, and much more.

Step 3: Make UI/UX Design “Innovative & Interactive part”

Whether it’s an app or a presentation, the first look – the appearance is something that grabs people’s attention. Thus, UI/UX design is the best part that speaks for itself in any video chat application. However, it is critical to have the needed UX components being designed at the utmost early stage. But, to succeed with the user experience it has to be prioritized  – visually appealing interface and intuitive navigation for better user experience.

If a newbie is able to navigate your video chat app easily without any guidance then that is the checkpoint for your successful video conferencing app. Of course, now your design can be called as the first influencer of your app to make a successful market reach.

Step 4: Development and Deployment “All about back-end”

Let’s get to know about the development and deployment, the utmost final steps for any video conferencing app before reaching the market.

Back-end Development “the server-end study”

It is a stage where the entire back-end development is taken into consideration including working on the app server, web server and database creation. This is the stage where the functional center of the app will be determined to proceed further with the process.

While designing a video call app, the key focus of the functionality is towards the optimization wherein the app is expected to perform well despite the large quantity of data. This will make the development phase more accurate and flawless and provides the video chat app the strength to manage multiple calls without any lag.


It is a technology that supports real-time communication over desktop and mobile systems using a variety of APIs. In other words, the term that works for any video-based application. The growth of this technology is largely because of its dependability as an open-source service and is supported by a number of software developer communities like Google, Opera and Mozilla.

The process of developing a mobile application begins with choosing the ideal technology stack. The two options available are:

  • iOS (Swift, iOS SDK)
  • Android ( Java, Android SDK)

However, the final stage of the tech stack ends up on with the requirement of features that are needed in an application. Of course, the cost estimation made till now is the final one to decide whether to  implement in the project and if so, how much etc., to have the best video conferencing app development.


In the final step, the code is tested for issues or bugs. These are resolved and ‘fixed’ in the testing stage. Overall, here the ‘clean’ final software product is user satisfaction, that’s apart from performance similar to peer apps in the segment.


The discussions above shows that in order to choose the perfect video conferencing app development strategy multiple steps need to be adopted. The fundamental factors are assessing resource availability and with the choice of perfect technology vendor.
