I've placed the Xcode project for RatioKey 1.1 in a GitHub repository.
This is an outdated Xcode project, unchanged since late 2010. Attempting to load it into a modern version of Xcode results in many errors.
Casually reviewing the code, eight years on, I'm reminded of the painful effort involved in getting it into a shippable state, and am mildly horrified at the needless complexity it oozes. Brother Ockham would not be pleased.
