What is fatigue tracking?
Fatigue tracking measures how your energy changes across real work periods so you can compare patterns instead of relying on memory.
Fatigue tracking only works if it starts from the work you actually do, not a guessed summary.
The value comes from comparing similar windows, not from reading one noisy day in isolation.
Once a baseline exists, Hydrogen can help explain what changed and where it repeated.
It replaces guessing with a baseline
If you remember how a week felt but not how it actually changed, fatigue tracking gives you a more reliable way to compare time periods.
Short answers

No. Wearables can add context later, but the baseline starts with your Windows work pattern.
It becomes useful once you have enough normal workdays to compare one period against another.
Start with the Windows baseline
Install Sarenica on Windows, track a few normal workdays, and then compare one period against another.
