Hey there! It's James, the developer of Harmonize.
I'm aware that Harmonize may have bugs-- there isn't a single piece of software that doesn't. And, I'm aware of the frustration that bugs can cause, especially when they come in an application you've paid for. So, I'm committed to solving any problems that arise with Harmonize as quickly as I can, and if need be, giving out refunds for the full version.
The App Store requires that I provide this support site, but rather than setting up a support form here, I think it would be more convenient for everyone to provide the email I created for this app:
the.guy.who.made.harmonize@gmail.com
If you run into any issues using Harmonize, please shoot me an email, and I'll try to resolve the issue as quickly as possible.
