BTS Calling Prank is a prank app to play with friends. It's an easy way to make fun of your friends and family by pretending that you have a friend of the famous Bangtan Boys.

The prank app lets you choose when the handsome boys will call you. You can choose from 5, 10, 15, 30, 60, or 120 seconds. It's very easy to use and you can set the timer from the settings menu.

Once the timer is up, you will get a call from one of the boys. The caller ID will be shown and it will be your choice to pick up the call or not.
