The best thing about the BlackPink Call You app is that it's FREE! You don't need to pay any money to use it. You just need to download the app, install it, and start using it.

The app is very simple and easy to use. You just need to press the "Start" button, select your favorite member, and start talking to them.

After that, you can watch the video of the member you chose, and you can also listen to their voice. You can also call them, or send them a message, and you can also send them a photo.
