Evidence before a score
Available sleep, HRV and resting-heart-rate trends remain identifiable instead of being flattened into an unexplained verdict. Missing inputs stay visibly missing.
Recovery starts with the evidence your account actually contains. EffortSignal keeps sleep, HRV, resting heart rate and subjective check-ins visible, then shows Readiness only when the recent record can support it.

Available sleep, HRV and resting-heart-rate trends remain identifiable instead of being flattened into an unexplained verdict. Missing inputs stay visibly missing.
Record readiness, sleep, energy, muscle comfort, stress and mood, with an optional note and supported measurements attached to the same local day.
Once enough recent evidence exists, Readiness combines only supported factors. Factor detail, coverage and confidence remain available beside the current result.
Recovery evidence stays beside the training load and volume that preceded it, so a quiet or demanding period remains visible without turning correlation into diagnosis.
The check-in editor keeps how you feel, optional measurements and a note together without requiring every field.

The complete Dashboard preserves the relationship between current evidence and accumulated work.

Create an account, connect a supported provider or record check-ins, and let the available evidence grow over time.
