Now its much easier to send messages on one of the largest social media platform called (whtasapp) and that too without saving number in your contacts list .This app uses whtasapp's public api to open a chat with any number you enter (a chat between you and that number, it is NOT possible to spy other conversations).


No contact is created on the device, so You do not need to save the number on your contact list in order to open the chat. Simply open the app, enter the number, click the button and the chat will open (if the number exists, otherwise Whtasapp will notify it).
