I have created a number of training aids to help me recognize morse code letters and words over the years, and I've used CW decoding apps on my phone to help me check if I'm sending copyable code. But I wanted to create a computerized coach that anyone could access to work on their sending skills and make it fun to use by tracking progress.

I've heard first hand that folks think they are sending copyable code when they are not.  Last week I was on 30m and someone was repeatedly calling CQ, but try as I might I could not decode their call.  Every time they'd send it there would be an unrecognizable character or two.  On each subsequent call it would sound like a different set of characters or non characters.  I tried to copy them to respond for about 3 minutes and gave up.  I kept seeing them call CQ on the waterfall but were never answered.  They needed to work on their sending.

It not only shows if your sending the characters you think you are, it gauges whether your inter-character and word spacing is good.  It gauges your overall timing accuracy and in QSO mode, those measurements work toward unlocking virtual rigs and badges.  For straight key mode it measures your DIT to DAH ratio and gives you real time feedback on what your ratio is through the gauges under the decode window (hint: you want them to all be as close to straight up and down as possible).
