Advanced Features To Add In A Video Chat & Conferencing App

advanced features in a video meeting app

High Camera Resolution

It is best to have 4K support camera resolution for the video calling apps as it would be really disturbing to interact with a hazy distorted face.

Remote Management

This feature comes handy when users are a large enterprise with multiple VC units. In that case the remote management allows the users to change the settings without having to physically walk from room to room.


Meetings on video calling apps needs focused attention and background noises with people talking, keyboard typing, kids crying, vehicular traffic, can be a big distraction. The Noise Blocking technology allows to keep these distracting noises at bay during the meeting. What’s unique about this technology is that it recognizes a real person talking, so when it doesn’t find a real person, it mutes the microphone automatically. Meanwhile, acoustic fence technology can also be used to block the unwanted noise. This technology does the marvelous job of building a virtual boundary around meeting area via the use of
microphones. This way the sounds not within this “fence” get blocked.


With this feature there is no requirement of manual framing. The absence of this feature would mean wastage of time of the moderator to zoom in & out the video. Here, the camera automatically adjusts the view so everyone present in the group can fit in the screen.

Push Notifications

This is a critical feature for Zoom like app as it allows people to be easily notified about missed calls, messages, updates, or anything else.

Data Encryption

With more and more business using video-conferencing apps, they all want security to be much preferred. In fact, the best way to build trust among people for your video-conferencing apps is to offer their safety by ensuring that their data is in safe hands. And what can be the best way of doing so than end-to-end encryption. This way one can ensure that only the sender and the receiver can see what is shared and discussed.

Host Tracking

In the physical meetings, the focus is generally on the hosts, speakers, or lecturers. The listeners and people in the group must be able to see & feel their body language, see the facial expressions and emotions to totally be in sync with the host. Now this experience can even be added in the video-calling apps through this feature of Host Tracking. The systems can actively zoom in on the host actively tracking their body movements and this way speaker can always be in the focus.

Optical Zoom

In the absence of zoom-in feature, it is not possible to see a certain thing clearly. Hence, this issue can be easily resolved with optical & digital zoom functionality. It is best to integrate optical zoom functionality as it offers better image & video quality in the video calling app.

Virtual Background & Green Screen

The host of video conference will be able to showcase an image/green screen in background using this very functionality. With the use of attractive virtual background images, it will be easier for the speakers to make the experience more appealing.

Live Video Editing

This feature will save a lot of efforts & hours of speaker in the video post-production. There are special effects and other quirks that makes the video a lot more interesting.

Whiteboard Camera System

This is an advanced camera system enabling to attach whiteboard owned by you. The app system will enable speaker to stream the content of whiteboard over video conference. This way the users will be able to download whiteboard contents and thus they have all the important information needed during the conference.

Virtual Hand Raising

Remember how to school we had to raise hands to get something answered so to avoid chaos that would occur when many talking at the same time. Same is with the video conferencing apps. This virtual hand raising functionality allows people to talk only when they raise their hands and this feature comes greatly useful during the webinars and during the discussions among many people when it generally tough to control who speaks and when.


Here a virtual whiteboard is offered to the users as there are often instances that during the meetings a manager or a supervisor has to explain a point to the team and white board comes helpful for this. They can use pointers or color a specific area and can use the virtual white boar to share images, draw graphs, charts or share numbers with the team members.


multiple video conferencing chatrooms appFor the online meeting apps, Chatroom is a crucial feature that has to be offered to the users and the good thing with mots video-conferencing apps is that it restricts users to only those having an invite code. Only the ones with the invite code can join the video call. As soon as the virtual chat room has been created, a person with the invite code can enter the chat room and join the ongoing meeting or the webinar.

Team Required To Develop A Video Conferencing Mobile App

Creating a video-conferencing app like Zoom is going to require a lot of efforts on the part of development team, and it is best to give the task of developing a video conference app to a development firm instead of a freelancer as a lot going in the making of such an app. These are the in-house resources that come along when you choose a video calling app development firm instead of a freelancer:

Project Manager

This is the person entirely responsible for the making and completion of the project. S/he manages the entire team on all stages and gets the work done and at the same time is the communication link between the development team and the business that is getting the app developed.

Android/iOS Developers

Now as per the decision of the business, a team of developers is decided. It can either be a team of Android developers, or a team of iOS developers, or there can even be two team of developers for both of the platforms, if the business chooses to get the app developed for both iOS and Android.

Back-end Developers

This team is responsible to handle the back-end work of the app as this is the core of the app and the backend developers have to be really adept and experienced.

UI/UX Designers

This is the team responsible for the look and feel of the app, like in terms of users’ experience with the app and this is an important factor deciding the success of the app, hence it is crucial to have a team of sound designers.

Quality Analysts

Once the app has been developed, it is vital to ensure that it doesn’t face any trouble as it runs, and to ensure that the work is working smoothly, we have a team of QA developers, who check the app for any glitches or errors. In case there is an issue, they report the development team so they can work on the same, and if the app runs smoothy without any errors then it is considered complete and ready to be launched.

How Much Does It Cost To Create A Video Meeting App Like Zoom?

There are several factors responsible for the cost of video-calling app, such as:

  • Hourly rates of developers
  • Design
  • Features
  • Number of Platforms

However, among these, the biggest factor influencing the total development cost of an app is the hourly development rates and this differs from location to location. For instance, the hourly development rates are higher in the USA, Eastern Europe, whereas it is a lot lesser in the Indian region.

Still to give a rough estimate, the cost to develop a video conferencing app with basic features will be somewhere around $20000-$55000, whereas to create an app with advanced features and technologies and for both the platforms, the cost will be somewhere around $45000-$80000, when chosen Indian region for development.
