Thank you for the advice. In my case it feels like it would take quite a bit of effort to pull out features from the software and make a stripped-down version available. My primary reason for wanting to share the code is that perhaps it will be a useful place for others to learn some things (though I don't think my code is stellar / exemplary and I know it has some serious shortcomings). I guess it isn't a big problem if someone releases a clone of my app for free as long as I somehow can require (request) they always link back to the original on their website and in the app itself. But I'm not eager to chase people around and pester them if they don't comply. I'm thinking I might wait for a full year since release (until February 2019) and just put out the whole code on GitHub with a 'free to do anything' license and a personal request that people always include a link to the original in the compiled app and on/through whatever websites they share it on.
