How to Embed Video Calls on App & Web

Integrating video call capabilities can elevate your app’s functionality and user experience. With the rise of remote work and virtual events, video calls have become crucial for daily communication. In this article, we’ll guide you on how to seamlessly integrate video call functionality into your app, making it more engaging for your users. Let’s get started!

Things You Need to Know Before Building a Video Call App

If you’re planning to develop an online video call app, there are a few essential things you should consider to ensure its success. Here are key things you need to know:

  1. Purpose and Target Audience

First, determine the purpose of your online video call app and identify your target audience. Will it be for personal use or business use? Knowing your target audience will help you design the app with their needs in mind.

  1. Technology

Choose the technology you will use to build your online video call app. WebRTC is a popular choice for building real-time communication apps, but there are other options available depending on your needs.

  1. Infrastructure

Ensure that your infrastructure can support the expected number of users for your online video call app. This includes bandwidth, servers, and other necessary resources.

  1. Security

Security is a significant concern for any online app, particularly one that handles sensitive information. Ensure that your online video call app meets industry standards for data privacy and protection. Implement user authentication and encryption to prevent unauthorized access.

  1. User Experience

Finally, prioritize the user experience. Ensure that your online video call app is easy to use, intuitive, and provides high-quality audio and video. Consider adding features such as screen sharing and recording to enhance the user experience.

Must-have Features of Video Call Apps

As the demand for these apps continues to grow, there are certain features that are essential to have in order to provide a seamless and enjoyable user experience. Here are some must-have features of video call apps:

  • High-Quality Audio and Video: The most important feature of any video call app is the quality of the audio and video. Users expect clear and stable audio and video, and any lag or distortion can quickly ruin the experience.
  • Screen Sharing: Screen sharing is a feature that allows users to share their screens with others on the call. This is particularly useful for presentations, demonstrations, or collaborations.
  • Recording: The recording is another useful feature that allows users to record the call for future reference. This can be helpful for business meetings or interviews.
  • Chat: A chat feature allows users to communicate through text during the call, which can be helpful for asking questions or sharing links.
  • Group Calls: Group calls are a feature that allows multiple people to be on the call at once. This is particularly useful for virtual events or remote team meetings.
  • Background Blur: Background blur is a feature that allows users to blur their background during the call, providing privacy and reducing distractions.

5 Best Apps for Online Video Call

There are countless video call apps and software available for video call. Most allow group video calls, and they differ in the number of users and level of interaction between them.

In this list – which is not a ranking – we will analyze the best and most popular, primarily free video calling apps and services. Not only for mobile devices but also for Windows/macOS and from a browser (such as Chrome or Firefox).

  1. Skype

Skype is among the oldest online video calling software and, according to many, the best video calling solution for two people or small groups. It supports up to 50 people; however, it only shows four users simultaneously, and the audio quality struggles. Still, it remains a powerful software where possible to make video-free calls, text-only chats, file sharing, and voice messaging. In business, users can enjoy complimentary features such as screen sharing, call recording, and real-time on-screen subtitles. 

For more functionalities, an upgrade to Skype for Business is possible. Skype is available on both Android and iOS smartphones, desktops for Windows, macOS, and Linux, or directly in its web version from the browser.

  1. WhatsApp

Whatsapp is the most popular instant messaging app used in much of the world. Suppose you do not want to burden your phone with new apps. In that case, you can make video calls on WhatsApp, accepting its limitations: fewer than eight participants, video calls online only from mobile devices, Android, and iOS. 

Therefore, it is the ideal solution for private use but not for business video calls with multiple users.

  • Zoom

Who hasn’t had a meeting, online class, or interview on Zoom? During the epidemic, it had a boom in subscribers; its popularity skyrocketed, earning it the title of the best app for having online meetings, according to industry experts. Zoom’s app is available for any device-smartphone, tablet, or on computer-or from a browser. It is very convenient to use as you need to create a link to the online event accessible from the web without downloading the app or having an account. The basic pricing plan is free: it allows unlimited video calls online between two people and video conferences with up to 100 participants for 40 minutes.

It allows the integration of valuable tools such as presentations, sharing one’s screen or a whiteboard to write on, and even muting participants. Those attending as auditors can use the “raise of hands” function to let them know they want to speak or write in the chat.

For more features, companies and organizations can access paid plans.

  • FaceTime

It is a top-rated app, yet it is only available to Apple devices. This means that for business purposes and meetings with many participants, it is not suitable. Instead, it is ideal for video calls online between friends and family, with excellent image quality. It supports up to 32 people simultaneously and allows the use of emojis and excellent filtering. Calling between Macbooks, iPhones, and iPads is quick if you take advantage of the package preinstalled by Apple on your devices.

  • Microsoft Team

Microsoft also has its platform for calls and video calls online. It offers one entirely accessible and enhanced paid version with several valuable features.

Microsoft Teams is quite popular. It has ‘weighty’ software, which may be heavy on a smartphone. It is ideal in the work and educational environment and allows for excellent group video conferencing. Available for Android and iOS and computer versions for Windows, macOS, and Linux.
