I can only agree with the people in this topic. Macdive is a great app with all kinds of nice features. I'm very happy to use this app for my dive log.
And yes, i had some issues with the app (some were little bugs, others were self-inflicted), but Nick was only an email away to either explain what i did wrong, or fix the bug if it was one.
Thanks Nick for the app, and the great support!
