Reduce Stress
See how meetings, travel, caffeine, and habits affect your nervous system.
Protect Long-Term Health
Track trends that matter years from now — not just today’s workout.
Energy management, not motivation management
Energy becomes visible Your wearables or manual check-ins
generate a 24-hour energy forecast. Know exactly when you have capacity
for deep work and when to protect recovery time.
Schedules adapt to you High-energy days get complex work.
Low-energy days get admin tasks. Your calendar respects your physiology instead of ignoring it.
Systems replace willpower Sleep anchors that work during
travel. Recovery rituals you can do in 10 minutes. When work spikes, your system adapts instead of breaking.
Measure Energy. Not Just Activity.
Most health apps count steps or workouts.
Entropy measures entropy — how ordered or depleted your system is over time.
That means you can:
- Train hard without burning out
- Work longer without draining recovery
- Sleep deeper without guessing why
- Spot issues before they become problems
This is how progress becomes sustainable

Every productivity system broke when work got stressful. Entropy adjusts to my stress load automatically. It's like a chief of staff for my energy.
