Need to Build a Chat Application : The Facts!

According to Facebook, WhatsApp is the leading messaging app, followed by around 1.3 billion users, and WeChat with over 1.2 billion users. Moreover, with this almost 80% of people use these messaging apps in their regular life. But, the fact is the modern businesses can not make use of these social media platforms for their business mainly due to security issues.

Wholly, these criteria simply prove the need for chat APIs solutions in businesses. Moreover, the reliability, scalability, and security factors of these instant messaging applications have made businesses look upon them when it comes to the growth of a business by connecting in real time with customers.

These real time chat applications are recognized mostly for their unique and everlasting features

Utmost Basic Features in an Instant Chat App, You Must Know!

You can find several real time chat apps in the market with numerous features specifying their uniqueness. But still, there are some ground-level features that are common for all.

However, these are some but there are more to dig deep into when it comes to real time communication applications. But I think it’s not enough, it’s better to have some idea about its benefits over certainly picked enterprises too.

What are the Benefits of Chat Application Over Variety of Industries

The utilization of these chat applications is not restricted to some of the industries as they have spread their wings wider across. 

Let’s have a look at some of these industries

1. E-Commerce & Marketplace – This industry makes use of video conferencing applications and has a live chat with customers. With a live chat facility, it communicates with the customers to place the order and have a track of delivering the order. And with video conferencing, it avoids the inconvenience of long emails and waiting time from both ends. Moreover, resolve the issues in the first place itself

2. Banking and Finance – This industry also makes use of both chat as well as video conferencing applications. In the banking sector, the employees use this chat app to communicate and share confidential files with other employees. In the same way in the finance industry, with the help of live chat, they interact and have a track of the current stock market. They also interact with their investors via video conferencing with regard to financial history and current market revenues. The drop-off in the shares and other related areas can be viewed and discussed instantly

3. Digital Healthcare & Hospitals – In the healthcare industry, with live chat apps, the patient can communicate with the doctor and set an appointment, share medical diagnosis reports, etc. and in the further run can make use of this video application to perform operations by interacting with the other surgeons present at the other end of the world and save patients lives

4. Online Education Industry – The online education industry is all about live video conferencing where the student can communicate with the teacher and have a regular learning lesson. With the chat app, the students can share and submit their documents/papers with the teacher and have them corrected.

Now, when you have got a clear idea about its necessity in a variety of fields. You must be thinking as to whether you can build an app or go for some ready-made one.

Well, that’s a cool thought to think about, let’s have a check over!

Choice is Yours : Readymade vs Custom Chat App

If someone asks you, what to choose: a ready-made or custom solution? What could be your response? Of course, the first thing that strikes your mind would be what is special about each of them. Exactly! That’s what I am going to tell you now but in brief.

Ready-made solutions can also be indirectly considered as a White label Chat application as it is one of the basic features found in them. as the name suggests, they are the solutions that are available as an in-built one that you can purchase and integrate into your existing application.

The main drawback of these ready-made solutions is that you can only avail the benefits of the features that already exist. But, since it is available with the restriction it won’t provide you with the facility to add extra features in future. But, it does allow your solution to be hosted on our cloud as well as on your premises or cloud as per your business needs

Whereas in the case of custom solutions, there is a need to build one from scratch. It involves the following steps

Build Custom Solution Steps
  • Check for a platform – have a clear idea as what is your targeted platform Android or iOS?
  • Mission of your app – What and whom does your app target ? This is so as to have an idea about the features that need to be included in the application.
  • MVP (minimum viable product) – It talks about the need as how the MVP look like including the features.
  • Duration to develop an application – Before starting must be clear with the idea of finding a specialized developer – in-house or remotely. Of course, with a set of supporting teams to set the duration to build an application

The overall highlight of these custom chat apps is that in the future you can add any number of features as per your business requirements with no restrictions. As an outcome of the above, both sound to be great in their own means, but finally it’s all about your needs.

Let’s have a look at what are the things being needed when building your own real-time chat app with CONTUS MirrorFly – “One of the market’s leading in-app Chat APIs & SDKs provider”.

    I have two groups of users. Lets say its Students and Professors. I need the chat app to only allow Professors to start the chats, while students cannot initiate them, but can reply. Also the Professors should have lists available for each of the students related to the specific classes. They shouldn’t be able to send messages to students that don’t belong to any of their classes. Is this something that can be achieved?
