Morse Command is the result of that joint effort.
What I really found helpful was all of the small, easier, time consuming tedium I didn't have to manually code. The main example is the website. It was 100% claude's generation and it is, IMO, spectacularly fit for purpose.
About the game itself: It uses the Koch method, which is the gold standard for learning morse code. It starts off at 20 WPM from the get-go. There are 80 levels, 8 boss battles, power ups. There's also a Daily Drill to keep you consistent over time. Its $4.99 in the ios app store, no ads, no IAP, just one time $5. Light weight at 2.8MB.
It's been very well received by the ham radio community on reddit and well, I'm proud of it, and wanted to show it off to you guys.
