    This Android app gives you both straight and iambic Morse code CW practice key oscillators for your Android device.
    Each key translates Morse code into English and CW prosigns in real time as you practice.

    Practice sending Morse code with a straight key oscillator.
    Settings include WPM, show/hide Morse code/text, choose sidetone 400Hz-800Hz.
    Adjust the WPM so that you can produce well formed DITs and DAHs at a comfortable speed.

    Practice sending Morse code with an iambic auto key oscillator.
    Settings include WPM, CW weight ratio, reverse paddles, show/hide Morse code/text, choose sidetone 400Hz-800Hz.

    Press and hold the Clear Code/Text button to adjust CW and Text label font sizes.

    You may use a real straight key with this app by connecting it
    to your Android device via an easily repurposed USB mouse.

    This Android app may be of interest to amateur ham radio QRP and QRO operators and CW or telegraph enthusiasts.

    For 10-30 WPM CW Morse code learning, please see my Koch Morse code trainer apps on
    Google Play and Amazon Appstore.

    Nice idea for an app. How about extending it so that it could key a real transmitter?

    Bluetooth or USB could be one used, or perhaps you could dedicate a corner of the screen to make a
    large blinking virtual white LED that could drive an external optical detector and that could key the transmitter.

    Good idea. I've considered it in the past but have otherwise been sidetracked. It would be best to do this with minimal additional hardware. A USB cable or BlueTooth seem feasible.
