Whether you are a startup, enterprise, or B2B/B2C business in the USA, this guide explains how to build a successful app like WhatsApp by leveraging the latest SEO, AI, and mobile technology trends.
Step 1: Define Your App’s Purpose and Target Market
The foundation of your messaging app starts with a clear value proposition. Do you want to serve global users, niche communities, or professional businesses? For example:
Business Messaging Apps → Secure communication tools for enterprises
Community Apps → Local groups, sports clubs, or event-based communication
Global Consumer Apps → WhatsApp-like experiences with multimedia sharing and real-time chat
Targeting the right audience ensures your app gains traction in the competitive mobile app development market.

Ongoing Maintenance & Updates → 15–20% annually
Outsourcing to a reliable U.S. app development company or partnering with a dedicated mobile app development agency can help reduce risks.
Step 8: Monetization Models
Profitable revenue models for WhatsApp-like apps in 2025 include:
In-App Advertising

Business APIs for Enterprises
Step 9: Post-Launch Optimization
Once your app is live, success depends on:
App Store Optimization (ASO) for Google Play and Apple App Store
Regular Security Updates
User Feedback & Iteration
Marketing & Social Media Campaigns
WhatsApp is one of the most popular messaging apps owned by Meta. Its popularity depends on various factors like instant messaging, simple user interface, and instant file sharing (images, high-quality videos, stickers, poles, map locations, PDFs, etc). WhatsApp launched “WhatsApp Business” in 2018 to enable smaller businesses to reach clients more efficiently. WhatsApp’s availability in over 180 countries increases its potential to reach over 2.7 billion people.
Since then, WhatsApp Business has been a popular business option. Over 50 million businesses use WhatsApp for marketing purposes. WhatsApp Business is quickly becoming a requirement, particularly for e-commerce businesses. As of February 2024, it is the App Store’s top-ranked messaging app.
Have you always been curious about how chat applications like WhatsApp are designed? Developing an app like WhatsApp may seem challenging, but with the right guidance and tools, you can surely make an app like WhatsApp in 2024.
Let’s understand how…
Developing an app like WhatsApp requires careful consideration of the basic features to add to your chatting application. Forget about the long lists of features or even the latest features WhatsApp continues to add every year. First, let’s understand some of the must-have features you should add to provide the best experience to your users. Let’s find out:
The primary function of any chat program is to send and receive text messages in real-time. Users should be able to converse one-on-one or in group conversations, supporting multimedia file sharing (images, videos, and documents).
As previously said, users’ primary priority is security. End-to-end encryption ensures that only the sender and receiver can see the messages, protecting user data from privacy violations.
Real-time push notifications update users on new messages, calls, and other app-related activities. This feature promotes user involvement and timely communication.
By integrating the chat app with the user’s address book, users can easily search and communicate through their connections. The software should also allow users to add new contacts by entering their phone number or scanning a QR code.
Users should be able to view their conversation history and send offline messages. Messages can be saved locally and sent when the user returns online.
Storing chat history on a cloud server allows users to view their discussions from numerous devices, giving a more seamless experience and assuring data continuity.
Monetisation options such as premium features, stickers, and themes can be made available through in-app purchases, which generate revenue for the app.
Combined with a user-friendly layout and cross-platform compatibility, these features can help you build messaging software that competes with WhatsApp and Telegram.
As a beginner in messenger app development, adding fundamental features should be your priority. Although you can learn about some of the latest features WhatsApp has brought in April 2024. Check them out:
- Two-step verification
- Edit messages
- Send photos or videos in HD quality
- Voice message status
- Companion mode
- Prevent scam/unknown callers
- Lock private chats
- React to messages through emoji
- Add description/caption with pictures, videos, or documents
- Create polls
- Status link previews
- WhatsApp communities
The credit for every successful app goes to its robust features and combination of powerful software tools. Have you been curious about the design and architecture behind chat apps like WhatsApp? Let’s understand this in detail:
- Each mobile device contains a local SQLite database that stores user data and communications.
- Devices communicate via HTTP and XMPP (Extensible Messaging and Presence Protocol). HTTP is widely used for web services, whereas XMPP is designed for real-time chat applications.
- YAWS Server is the server that processes web requests, notably those sent over HTTP.
- The custom ejabberd Server Cluster oversees message routing and user presence. It is built on the ejabberd framework, a powerful XMPP server.
- Media Data manages multimedia messages such as images, movies, and voice notes. The figure depicts a pipeline in which media is treated differently than text communications.
- Media Store CDNs (Content Delivery Network) are distributed systems that serve material based on the user’s geographical location, ensuring quick and efficient access.
- Databases like Mnesia DB Cluster, MySQL/PostgreSQL, and Riak are used in database management.
- FCM (Firebase Cloud Messaging) and APNs (Apple Push Notification Service) are used for push notifications. FCM is used for Android, whereas APNs are used for iOS devices.
- Write-only data operations can be written to storage but not read or updated. It protects data integrity and security during particular procedures.
This diagram demonstrates WhatsApp’s distributed architecture, which includes relational and NoSQL databases, specialised servers for messaging, media storage solutions, and connectors with platform-specific push notification services.
The separation of components ensures scalability and performance over a large user base. WhatsApp’s success is due to its ability to communicate in multiple languages and its careful integration.
