“CW with Me is an app for helping learn morse code. Getting away from impersonal, computer generated morse code, CW with Friends allows you to send and receive messages with real people, over the Internet.
When you receive a new message it is initially hidden from view. You can play the CW, practice decoding it then view the original message to see how close you were.
You can send and find CQ messages as well as call your friends. In Settings you can manipulate the code speed, set a Farnsworth value and change the CW pitch.”
