WhatsApp Bomber is an application that allows you to send an incredible amount of SPAM messages to your friend's (or no friends) WhatsApp until the smartphone is completely blocked.
This app is a prank in itself where it automatically loads and sends over a thousand text messages to any of your friend's WhatsApp contact such that their phone completely stops working.
How to use:
After you have installed the app, you select the bombardment level of batch messages. These are labelled as a range from 1 to 5. Once selected, click "copy bomb to clipboard", which will automate the sending process. Once completed, bulk messages are ready to be sent out as bombs.
