Yes, I'm that Leif Wright. About five or six years ago, there were no good Bible programs for Mac OSX; at least there were none that did what I wanted them to do.
At some point during the programming, I realized other people would like the same features, so I offered iBible for sale and people loved it.
I haven't offered a new version of iBible since 2003, but people still use it and still send me e-mails about it. Since it hasn't been updated since then, I am now offering it for free while I mull over whether I want to update it. I have lots of ideas for a new version of iBible, but the reality is, it has stopped being such a personal project, and as such, I have lost a lot of my passion for programming it. The old version of iBible does everything I need, so until I need something else, I kind of lack motivation.
