Practice sending International Morse code with this straight horizontal lever CW Morse code practice oscillator app for Android smartphones and tablets. This app is stand alone and DOES NOT directly interface with your radio to provide a keying device. However, you may use the app's flashlight feature, a phototransistor, and a 2-wire connector to straight key a transmitter.

This Morse code practice oscillator translates International Morse code into Latin letters, Arabic numerals, punctuation, CW prosigns, and characters á, ch, é, ñ, ö, and ü in real time as you practice.

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

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