You don't need to save contact details anymore just to start a WhatsApp chat.

Direct Chat (DC) is in your service.

Just enter the contact number in this app and hit the WhatsApp button to start chatting with the recipients without saving their numbers.

Direct Chat supports both WhatsApp and WhatsApp Business.

Contacts: Save contacts in DC while starting a chat for later use. Name the contacts to easily identify them.

History: A history log is maintained for the attempts you made to start the chats. You may copy phone number or message from history. You may delete the history when you don't need it anymore.

Please note, to use this application you must have the WhatsApp or WhatsApp Business app installed and active in you device.
