KEY FEATURES IN MESSAGING APPS

Let's take a look at what core features should be used to make messaging easier in 2024.

1. AUTHORIZATION

App users should have the possibility to create a personal account. The wise idea is to implement a user sign-up option in one click via social media (e.g., Facebook, Twitter, Instagram).

Depending on the app’s objectives, you may include authorization via email, phone number. For increased security, it is possible to interconnect with the device with the help of confirmation SMS.

2. ACCESS TO CONTACTS

For enhanced user experience, your messaging app should automatically access to existing user contacts and get them imported to the messaging app. A strategic step is to highlight for end-users which contacts already use this messenger and give an option to invite those that still don’t.

It is also a wise aspect if users can engage others to join the messenger with a simple invitation.

3. ADVANCED CHAT OPTIONS

It is hard to create a product on the same level as the giants like WhatsApp or Facebook Messenger in in this highly competitive market. As a startup project, your messaging app should have minimum functions to be validated. For the update and final deployment, think of advanced options that will bring value. Integrating top social channels and developing a more personalized user experience can help your product succeed on the market.

4. EXCHANGE MESSAGES AND FILES

These days, users need to have the possibility to exchange files, videos, photos, and other content. Therefore, make sure that your messaging app supports different app attachments.

This feature can be implemented by using distinct APIs. Do not forget that your app should have an option to send files from the device and capture real-life moments from the app directly.

5. SHARING REAL-TIME LOCATION INFORMATION

Users can share their location with others in many apps, like parking spots, offices, restaurants, etc. This feature is developed by utilizing packages of Location Manager Class on iOS and Android.

Telegram messenger has implemented this feature, which provides excellent user experience. App users can even create routes from the starting to the destination point.

6. PUSH NOTIFICATIONS

It is an essential element in any messaging app development. It is the function that allows the user to check whether someone sends a message or not. Developers use Google Cloud Messaging and Apple Push Notifications to implement this functionality.

7. CLOUD STORAGE AND BACKUP

To generate user satisfaction and get user retention, your application needs to be customizable. The users do like the idea of playing with app interfaces, themes, and colors to make it more personalized and attractive. Keep this in mind when comprising the app functionality list.

TOP 7 most secure messaging apps in 2024    
 

Digital technologies are all about making life comfortable, but at the same time, it is about security concerns.

Today there are secure messaging apps with end-to-end encryption built on blockchain technology that is absolutely safe and secure. Still, before thinking of making a secure app, consider whether it meets your business objectives or not. 

Do you want to know which are the most secure messaging apps out there and how they can protect your valuable data? We compiled a list of reliable encrypted messaging apps because the struggle to keep our data secure is fiercer than ever.

TECHNOLOGY STACK TO BUILD APPS LIKE WHATSAPP AND TELEGRAM

First, we list possible tech stacks to utilize in chat app creation, followed by for a few successful messaging apps. It makes sense to understand how these applications are created.

WhatsApp tech stack

The Technical Stack used to develop WhatsApp includes Erlang, FreeBSD, Yaws, PHP, and XMPP.

• Erlang - functional language used to script real-time chat apps. 
• FreeBSD - open-source operating system to power modern servers and embedded platforms.
• Yaws - Erlang-based web server used for dynamic-content apps to run WhatsApp as a standalone web server.
• PHP - general-purpose scripting language for web development.
• XMPP - the communication protocol - the core of WhatsApp for sending real-time messages.

Let’s dive right into these insights.

TECH STACK TO BUILD YOUR MESSAGING APP

Depending on your product’s goals and functionality, you should understand creating a cross-platform or native messaging app. The difference lies in the app availability of the app across the majority of platforms simultaneously or individually for each operating system.

Both options have their pros and cons. Native app development ensures higher system performance, stability, security but requires more investments.

MOBILE APP DEVELOPMENT

BACKEND DEVELOPMENT

Server-side software can be coded in PHP, Ruby, Erlang, and similar. Your software development vendor should advise you of what is more suitable to use in your case.

Also, one of the most common product architectures is a software bundle of LAMP. Linux as the operating system, Apache- web server, MySQL database, PHP as a back-end language.

Alternatively, you can use a PostgreSQL database, Nginx web server, Nodejs, Ruby, or JavaScript for the backend development.

It is also necessary to use distinct services and libraries, namely:

• Amazon services - for data storing
• Socket.io - library for real-time communication between a browser and server
• Social media integration - Facebook, Instagram, Twitter, etc.
• Analytical tools - Flurry, Google Analytics, Firebase, MixPanel, etc.
• Maps & Navigation - Google Maps, Google Places
• SMS services - Twilio
• Email marketing - MailChimp, Elastic emails
• Payment gateways - Braintree, Stripe, PayPal, etc.
• Push notifications - APNS (iOS), FCM (Android)

The general idea is to go for open-source technologies, which prevent building everything from scratch. Instead it is possible to use existing well-proven libraries and frameworks.

When selecting a tech stack for your messaging app, put users and their experience in a priority and consider the speed, performance, and security of the chat app.

TECHNOLOGIES USED TO BUILD A WHATSAPP MESSAGING APP

Operating system FreeBSD is used in this app. Its developers believe that the Linux system is more bug-creating, which is a somewhat debatable statement.

Initially, the system used XMPP (Extensive Messaging, Presence Protocol) to manage one-to-one and group communications. Further, the team created the internal protocol to support communication with end-to-end encryption.

WhatsApp uses YAWS (Yet Another Web Server) for data storing and HTML5 WebSockets to create a solid connection between a server and messenger.

The system uses LYCE/LYME architecture consisting of open-source solutions to develop highly available and dynamic pages.

• Operating system- Linux
• Web server – Yaws
• Databases – Mnesia, CouchDB
• Programming language- Erlang

To note, Elixir programming and its Phoenix framework are great to utilize for complex and high-load projects. These technologies ensure smooth system operation, remarkable efficiency, and the ability to handle lots of traffic.

TECH STACK WITHIN THE TELEGRAM APP

Telegram is one of the most significant messaging apps with the high protection and smooth performance. As far as it is known, the messenger was coded with the following technologies:

• iOS app – build by utilizing Objective C and partly Swift
• Android app – created with Java programming language
• Windows Phone app – uses C#
• Web platform – uses Javascript and Node.js
• Mac app – is developed with Objective C

Also, the Telegram team developed a specific data protocol, MTProto Mobile Protocol, that ensures the speed and security of its service.

TECHNOLOGIES UTILIZED IN THE SKYPE PRODUCT

Before Microsoft purchased Skype, the product used C++ for the back-end in Debian servers. Further, the team included new services by using Azure Suite (written in C#).

The client Skype apps include the C library to support the low-level app functionality. To mention, Skype is a cross-platform product, and only a thin layer of client apps (UI layer) uses Java and Objective-C for Android and iOS apps correspondingly.

CHAT APP MONETIZATION STRATEGIES

How can you monetize your messaging application?

We have an answer for you with a few options to build revenue streams in this app type. These strategies include:

• In-chat advertising – these are multiple ways to include ads inside the messaging application. This can be a banner ad, pop-up ad, native ad, and similar. Viber messenger uses this strategy and shows targeted ads and messages and earns millions.
• In-app purchases – this model implies users pay for some advanced app features, access specific content, remove the ads in the messaging app, purchase sticker packs or games. The latter option is used in the LINE chat app, where users play right in the messenger.
• In-app payments – corresponds to the typical monetization strategy, where users make payments inside chat applications.
• Integration of a chatbot – this is an advanced monetization possibility once your app gets user interest and base. It allows you to gain revenue from CTR (click-through rate) by providing relevant recommendations.
• Sponsorship – in this model, revenue is generated via in-app sponsorship to create brand awareness. This method is best to utilize once you have enough pull of app users.
• Pay per download – you may use this method if you are sure to provide a unique and new app functioning, and you tested the hypothesis that users will purchase the app. In general, users buy only those apps that are very specific and have top performance.
• Subscription fee – similar to pay per download, but the payment is made regularly, only when clients use a messaging app (e.g, monthly, annual basis). Interesting fact, that the WhatsApp initial cost $0.99 per year after a trial period.
• Content merchandising - creating chat themes, wallpapers and stickers related to any brand. The promotion of the brand brings win-win results for the app and the brand. 
• Official accounts - this type of messaging app is built for brands, public figures or celebrities who are willing to get close interaction with followers.
• White labelling - this strategy supposes chat app development for enterprises’ internal use or customer support.

Either method you select, base your monetization strategy on the market analysis, current user experience. Also, these days users demand top-notch app performance and service quality to pay for it.

CHALLENGES OF BUILDING A CHAT APPLICATION

Before you proceed with the actual development of the messaging app, consider the following challenges on the way and further. This information will help overcome pitfalls and remove risks and future troubles in a messaging app functioning.

1. DEFINING REAL-TIME FEATURES

The industry of messaging apps is led by giants that have raised the bat and, to tell the truth, it will be hard to compete with them. On the other side, we have users that demand new features, stability, and functionality. To become a competitor, the messaging app should be way much more than a chat app. After a successful launch of MVP, think of all the features for user satisfaction:

• Custom fonts and stickers
• Chat muting
• Privacy status updates
• Video and voice calls
• File transfer

2. SECURITY ISSUES

High-end app security and protection is the number one task during messaging app development. It is necessary to provide personal data protection, message encryption, and build secure project architecture.

Ensure that you provide as much protection as possible, namely:

• end-to-end encryption via protocols (e.g XMPP)
• usage of cryptographic keys
• plan the product architecture for secure data storing
• include privacy policies when using your chat app
• develop extra functionality, which users can enable, for messenger protection

3. THE TOOL STACK

To make your app work, it should first be well packed and built. Think of existing apps and find case studies that will help to define the tech stack best working for your project. 

4. OVERLOAD OF THE SERVER

This issue may arise with the growing number of app users. Optimization of an app like WhatsApp requires loads of technical efforts and capable developers.

Choose the server setup and capacity, also supported by proper hardware, to quickly ensure app scalability. Make sure that servers are tuned up to provide stable work during the peak load periods.

It is highly recommended to plan and create a list of potential server bottlenecks with a precise action plan.

5. FLAWLESS APP UPDATES

Messaging apps have a constant connection with their users and constantly process their data. During new functionality deployment and app updates, make sure not to lose existing data by servers and architecture configuration.

Scalability of the real-time chat apps is a rather challenging assignment, which is highly dependent on the set architecture.

6. STABLE CONNECTION

Many reasons can influence the network loss and switch from smartphone internet and Wi-Fi. To note, during such losses, the last message can be lost in case of a temporary disruption.

Thus, you should create your messaging app to outline your app as a reliable tool that keeps the connection stable and reproduces lost messages during disconnection.

HOW LONG DOES IT TAKE TO DEVELOP A CHAT APP

The timeline required to develop your messaging app depends on several factors. These include but are not limited to:

• number of platforms you plan to build your product for
• the complexity of features and design
• number of features included
• attributes of the selected software development vendor (location, rates)
• number and peculiarities of 3rd party services to integrate

Any software development consists of special services like UX/UI design, Architecture planning, iOS development, Android development, Backend development, Quality Assurance, etc.

In general, be prepared that it takes around 3-5 months to develop an MVP of the chat app. Note that in most cases, this involves only basic app functionality. In terms of the budget, the sum is highly dependent on the development vendor you choose.

The 3-5 month of development corresponds to $25,000 – $50,000 for one platform (iOS or Android). At this cost, usually, you receive a team of 4-6 specialists like iOS/ Android developer, Backend developer, QA engineer, Project manager, Designer.

To visualize what to expect, here is a chart with development time per feature. Keep in mind that we are discussing MVP features for the first launch. Later the app may be updated with new functionality.

Thus, plan your timeline and budget accordingly. A wise strategy is first to finalize your product concept, business vision and prioritize app functionality.

CONCLUDING IDEAS FOR CHAT APP DEVELOPMENT

Online communication is a core part of our daily life – 80% of adults, 91% of youngsters text each day. This area will evolve and innovate each year, which has a vast potential for your investment today. The more modes of communication exist, the greater social satisfaction is.

Here is a short case study for more practical information about the messaging app and the development experience. The expertise of Addevice covers the development of different apps, including entertainment and messaging. One of the relevant projects was “WOO – Women’s dating platform app,” a dating app and messaging platform to get connected.

The MVP of the app was built on stakeholder requirements based on the following tech stack:

• Swift, Java
