Flash Message

Have you ever wanted to send one and only one message to someone on WhatsApp without adding a new contact?
Have you wanted before to open the chat directly with someone you had a recent call with?
If so and took you a lot of time to do that, Flash message made it one tap away with a 2 megabytes application.
Just copy a number from your call logs or write down one and it will direct you to the chat with them.
