For those of you who want to enjoy the everyday creativity Chronodex brings, but already moved on to digital note taking or scheduling, I've made Chronodex available for you in digital format.
GhostWriter Notes iPad app is one of the best digital notebooks you can find on a tablet. Since the creation of Chronodex, many of you want to apply the idea in your own preferred paper and notebook size and format, some of you adapted it into stickers, printed on tracing paper. Now you can have the same fun on your iPad, just download the Chronodex Daily GTD for GhostWriter Notes JPG, save it in your photo library, choose the image from your GhostWriter Notes "paper" setting, that's it. (Update: seems like the same JPG file works very well on another iPad app called Noteshelf too)
GhostWriter Notes is like a scrapbooking page with dozens of nice features you can play with your Chronodex core. I love the choice of ink pen which gives you very fine lines to color your pies. You can simply use the Chronodex core as your mindmapping center on GhostWriter as well. If you look into the details of the format, I'm sure you will find your very own creative use of the core.
