WhatsApp is one of the most popular messaging apps in the world. It has over 1 billion active users and is used by people from all over the world. There are a few ways to make a WhatsApp-like app. One way is to create a WhatsApp account and use the Facebook app to create a WhatsApp group. You can then invite your friends to join your group. Another way is to use the Google Play store app to create a WhatsApp group. You can also use the App Store’s built-in messaging features, such as voice and video chat, if you want to send messages through WhatsApp instead of using Facebook or Google Messenger. If you want to make sure that your WhatsApp-like app works with both Facebook and Google Messenger, you need to set up two separate accounts for each platform. On Facebook, set up an account for your main account and set up an account for your WhatsApp account. On Google Messenger, set up an account for your main account and set up an account for your WhatsApp account.
