What FatigueSense tracks

Six digital biomarkers from your wearable and daily check-ins, combined into one picture of your energy.

HRV

Heart rate variability at rest, a window into your autonomic recovery state.

Sleep stages

Deep, light, and REM tracked nightly to show how sleep shapes your next day.

Step activity

Daily movement monitored within your personalised energy envelope.

Fatigue assessment

Twice-daily check-ins covering energy, symptoms, and brain fog in under a minute.

Pacing score

Your daily energy budget, recalculated automatically from your baseline.

Symptom trends

Patterns in fatigue, pain, and cognition tracked across weeks and months.

No new hardware. Just a smarter way to use what you have.

Your wearable already collects the data. FatigueSense turns it into something useful for people with energy-limiting conditions.
