Quantified Life
Back in 2009, I decided to track my time minute by minute for two weeks as part of an effort to improve my productivity. As Peter Drucker famously said, “You can't improve what you don't measure.” At one point, I had optimised my life to the point where there wasn't any joy left, and I realised I needed to slow down rather than live as a servant to the system I had created. Nowadays, I take a more relaxed approach to productivity, but the time-tracking habit has stayed with me to this day.
Time tracking has become a habit rather than a scorecard I use to judge myself. It feels good to look at the hard evidence of how I have lived.
Recent days
Hours per day across the last thirty days - the view I use to rebalance my routine, and the closest thing to my paper tracker. Slice by area of life, or by activity to see what those hours actually went on. Tap a label to show or hide a line; the axis rescales to what is on show. Sleep starts hidden under Area so it does not flatten the rest. A hollow marker means that day was only partly tracked.
Composition over time
Minutes per area of life, stacked by category. Switch between weekly, monthly, quarterly and yearly buckets to zoom in on week-by-week rhythm or compare years at a glance. Areas are ordered by their overall total.
- Sleep

- Relationship
- Routine
- Learn
- Fun
- Health
- Productivity
- Finance
Year over year
Same calendar month, drawn across years. Pick a category to see how this year compares to the last, with partial years ending where the data does.

What, who, how, why
The inner pie shows the share of tracked time for each area of life. The outer ring breaks the highlighted area down along one tag axis: what I was doing, who I was with, the state of mind I was in, or the project. Click another area to switch focus, and use the buttons above the chart to change the axis. Tags within an axis are largely exclusive, so the outer ring adds up cleanly to its parent slice.

Sleep
Each column is one calendar day, with sleep periods drawn against a 0:00–24:00 axis. The teal line on the right axis traces total sleep per day in hours.
