I no longer have time or interest to properly maintain RatioGhost. I am looking to sell the website/code/business. Please contact me if you're interested in buying it.

Ratio Ghost is recommended to be run on Windows.
Versions for Mac and Linux were available in the past. They might be available again in the future if I find time to update them. If you really want to run Ratio Ghost on one of these platforms, consider sending a small donation.
