Adaptimist Lab
Optimizing Your Energy Levels
A day-planning sketch that helps you match different kinds of work to different kinds of energy. Map your wake and sleep window, add meals or snacks, then colour your hours to see where your plan aligns with likely fluctuations in effort and attention.
Lab Experience
Optimizing Your Energy Levels
Matching task type to capacity
Orientation
Set your wake and sleep window, add meals or snacks if they matter for your routine, and then colour a few hours of the day according to the type of work you expect to do. You do not need to fill every hour for the planner to be useful.
The goal is not to create a perfect schedule. It is to notice whether your heaviest, most interactive, or most demanding work is landing in parts of the day where it is more likely to feel sustainable.
Developing a productive routine
Your blood sugar changes over the course of the day. That means the kind of work that feels easy can shift too. Set up your day on the left, then colour your hours. When you’re ready, click Check my plan to see the trade-offs.

What you may have noticed
Most people already know, at least vaguely, that some hours are better for deep work, some for reactive work, and some for recovery. What this lab does is make that intuition visible enough to revise. A good schedule is rarely about maximizing every hour. It is usually about making fewer avoidable mismatches.
If the planner surfaced tension, that is useful. It does not mean your day is wrong. It may simply show where your responsibilities are asking more of you than your current rhythm easily supports.
How this works
This lab is a planning sketch for effort regulation. It assumes that alertness, readiness, and cognitive ease are not evenly distributed across the day, and that different kinds of work place different demands on attention, memory, social bandwidth, and self-control.
What to notice as you use it
As you assign work modes to different hours, notice where your schedule feels naturally aligned and where it feels strained. Some mismatches are unavoidable, but many are invisible until you map them.
- Notice which hours seem best suited to immersive or creative work.
- Notice where interactive, reactive, or administrative tasks may be easier to place.
- Notice whether you have protected any genuine buffer time, or whether every hour has been claimed by demand.
Why the experience is designed this way
The app combines a simple energy curve with an hour-by-hour grid so you can move between an overall pattern and specific scheduling decisions. The curve is deliberately approximate. It is there to provoke better planning questions, not to announce a biological truth about your day.
The mode colours help distinguish different kinds of demand: deep focus, reactive triage, social interaction, physical activity, recovery, and sleep. The planner is most useful when you treat those as meaningfully different forms of work rather than as interchangeable “busy time.”
The science or theory behind it
This lab is loosely informed by work on circadian rhythm, effort regulation, glycemic fluctuation, attention, and self-management. Across a day, people often experience meaningful shifts in alertness, motivation, and cognitive control. Those shifts can be influenced by sleep, food, stress, activity, habits, chronotype, medication, workload, and many other factors.
The planner does not try to model all of that complexity. Instead, it uses a deliberately simplified heuristic: some parts of the day are better for ramping up, some for sustained focus, some for lighter or more reactive tasks, and some for recovery. That simplification is useful because schedule design often breaks down not from lack of ambition, but from lack of differentiation.
Limits of the model
This is not a medical, nutritional, or chronobiological assessment. It does not know your actual glucose, hormones, sleep debt, diagnosis, or life constraints. It is best used as a reflective planning tool that helps you test whether a schedule feels more realistic when work type is matched more intentionally to likely capacity.
If you want to go further
After using the planner, compare it with a few real days instead of treating it as correct on first pass. The most useful pattern is often the gap between the schedule you wish you could sustain and the schedule your body and attention actually support.

This lab is a heuristic planning aid rather than a formal assessment. It is informed broadly by work on circadian rhythm, energy management, glucose-related variation, and effort regulation, but it should be read as a practical sketch rather than a validated model.
