Having used a vertical scheduler for years, I stumbled upon the Chronodex and immediately took a liking to it. It is visually appealing and is based on the clock face. Being a visual person myself, this way to represent my day makes more sense in my mind. At a glance it is easier for me to see what I have going on for the day.
Chronodex by Patrick NgI used the Chronodex until I found the simpler version called the Spiraldex by Kent from Oz. It is based on the Golden Ratio of the Fibonacci Spiral.

I then changed to using a stamp version of the Spiraldex since I started using a Hobonichi Techo. Because Hobonichi pages are very thin and made out of Tomoe River Paper, stamp ink can bleed through, therefore I use the chalk type stamp ink like Tsukineko Versa Magic Dew Drop in a lighter shade. I also only stamp the second impression onto the page, with the first impression made on scrap paper. This way I can eliminate the bleeding and minimise the ghosting.
I use colour coding for my schedule, have done so for years so of course I applied the same for the Spiraldex.
When there are blocks of time that I need to mark on my schedule:
When I have a few things happening in the day that I want to capture, I mark them with lines:
Some days can look like this:
I eventually changed the markers for my work day and my son’s school day to just be designated as:
This way I can still mark off other blocks of time within the day without having to superimpose them.
Notes are also colour coded to easily differentiate which tasks/notes are for each aspect of my life.

I also used both the spiraldex and the chronodex and I found myself better with the spiraldex between the two, it was clearer and more schematic. After a few days, however, I realized that the round shape, spiral precisely, confused me and I did not get the visual impact of the time taken to do what. So I used the color code to differentiate the activities, but also the color code (which I almost never use except in a minimal version) distracts me and confuses me! Unfortunately I am very linear and specifically I call myself “vertical linear”. ) I admire very much, however, this type of tools that allow you to visually monitor their times and I’m always curious to discover new ones!
As I always say, at least try something once. Glad you tried and figured out it doesn’t work for you. 🙂 for November I will use the Chronodex.
