How to Create app like WhatsApp:

Creating a successful messaging app is a detailed process. From ideation to maintenance, every step requires careful planning and execution. Here’s a comprehensive guide to Create App Like WhatsApp:


Before diving into development, understand the market. Identify your target audience. What do they need? What features are they missing in current apps? Look at successful apps like WhatsApp and Telegram. What makes them popular? Analyze competitors to find gaps in the market.

  • Market size

    • People prefer messaging applications to SMS, calls, and email clients like Gmail because messengers are more convenient than other communication means. Below we have some numbers that prove that messaging apps are up and running: 
    • ·         Statista reports that In April 2022, WhatsApp had approximately 2.44 billion unique active users worldwide, up 6.4 percent compared to the corresponding month in 2021.
    • ·         The chat apps market will keep up with this overall growth, and by 2025, users will make four out of five mobile connections with a smartphone
    • ·         The messaging apps’ average revenue was $8,7 billion on 2021
    • After considering all the information above, the messaging apps market will continue to grow, and that there is still room for new messaging apps. 
  • Competition

  • But before you create a WhatsApp-like project and enter the messaging applications market, you need to get to know your potential competitors, i.e., other most popular chat apps in 2022 as of right now based on the number of monthly active users.
  • Now, it is time to determine what steps you need to take to create your WhatsApp-like messaging project. 


Once you’ve validated your idea, it’s time to plan.

  • App Platform:

    • Decide whether you want to launch on iOS, Android, or both. Consider your audience's preferences. iOS users might have different expectations compared to Android users.
  • Tech Stack:

    • Choose the right technology stack. For iOS, Swift is popular. For Android, Kotlin or Java works well. Backend services can use Node.js or Ruby on Rails. Don’t forget about databases like MySQL or MongoDB.
  • Hire Mobile App Developers:

    • You need skilled developers. Look for those with experience in messaging apps. Check their portfolios. Consider both in-house and remote teams. Hiring the right talent is crucial.
  • Monetization Strategies:

  • How will you make money? Consider in-app purchases, ads, or subscription models. Each has its pros and cons. Choose the one that aligns with your app's goals and audience.

App Designing

Good design is key. It should be user-friendly and intuitive. Start with wireframes. Outline the basic layout and features. Move to high-fidelity designs. Focus on aesthetics and usability. Test your designs with real users. Get feedback and iterate. Remember, first impressions matter.

App Development

This phase is about bringing your designs to life. With the creative part done, it’s time to get down to business.

In this step of “how to build an app like WhatsApp” we deal with coding. This process can be divided into two different aspects. Namely:

- Front-end development

- Back-end development

During the first part, mobile app developers work on the client side i.e. UI/UX design, and add functionality to the same.

Moving to the latter one, it has more to do with APIs, coding, and connecting the different components.

  • Front-end Development:

    • This is what users interact with. It includes designing the UI, implementing animations, and ensuring a smooth user experience. Tools like React Native or Flutter can be helpful.
  • Back-end Development:

  • This is the backbone of your app. It handles data storage, user authentication, and server-side logic. Ensure your backend is scalable and secure. Use cloud services like AWS or Firebase to manage infrastructure.
  •  Due to the amount of work, its importance, and the complexity of the different technologies, this is the single longest step of developing an app like WhatsApp. For that reason, it is also advised that the client maintain good communication with the development team. In any case, with an app developed, it’s time to go with testing.


Testing is critical. It ensures your app works as intended. Conduct various tests:

App testing is an important process. It doesn’t just ensure the app is as per customer demand, but also takes it up to market standards.

In addition to this, it is mandatory to ensure the app is secure and they are big free before going for deployment. This greatly reduces the chance of getting the app rejected.

Fix any bugs and optimize performance. A well-tested app reduces future issues and keeps users happy.


Ready to launch? Choose your app stores (Google Play, Apple App Store). Prepare your app’s listing. Write a compelling description. Use high-quality screenshots and videos. Set up analytics to track user behavior. Submit your app for review. Once approved, it's live!


Your work doesn’t end with the launch. Regular updates are necessary. Fix bugs, add features, and improve performance. Listen to user feedback. It’s invaluable for making your app better. Keep an eye on analytics. Track how users interact with your app. Identify drop-offs and fix them.
