This Amateur ham radio software app for Android devices allows you to practice sending Morse code with an iambic paddle practice oscillator. This Android app DOES NOT connect to your ham radio to provide a keying device.

Practice sending Morse code with an iambic paddle oscillator. Simply touch down on the DIT and DAH paddles instead of pinching, squeezing, or flinging the paddles.

Settings include WPM, CW weight ratio, reverse paddles, show/hide Morse code/text, choose sidetone 400Hz-800Hz.

Touch and hold both paddles to cycle between DIT and DAH and feel the iambic rhythm.

This iambic practice oscillator app 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.

Here is a brief instruction on using an iambic paddle key to send Morse code:
