Additionally, you must know what your target audience needs, and provide features that will prove to be a valuable addition to their life, and that will make them prefer your app over others.
After you analyze the market, audience insights and demographics, you must now think about which platform to build it on, whether iOS or Android or both. You must take into account all the pros and cons of each option before reaching a final decision.
How will you monetize?
Another important factor of your app is how you will earn money from it. There can be many ways that you can monetize your app, one is to go for advertising and built-in ads, the second is to collaborate or do sponsorships, and third is to use in-app purchases. Any of these options enable you to earn money from your app.
Hire a dedicated development team
You must hire a team of professionals that are composed of mobile app designers and developers. This team can help you achieve all the goals for your app, and they work efficiently because of their wide knowledge and skills around frontend design and backend development while at the same time making the app user-friendly.
Additionally, End-to-end encryption is also necessary for an instant messaging app. The platform should be secure and protected so that potential users do not get scared that their data is likely to be leaked or misused while using your app.
How much does it cost to build an app like WhatsApp?
Now is the time to address the most important part of the article – cost. An instant messaging app similar to WhatsApp would cost in the range between $100,000 to $1,000,000.
