A recovery score needs sleep, HRV, resting heart rate and your own baseline.
daygauge's readiness score, out of 100, uses sleep, HRV and resting heart rate compared with your own averages.
Start with what your own data can show.
Recovery scores are popular because people want to know whether to push or ease off.
The risk is false certainty. HRV and resting heart rate are useful trend signals, but they are noisy and need your own baseline and your sleep for context.
Readiness weights sleep 30%, HRV 35% and resting heart rate 35%, each against your own recent average. It gives a verdict: Ready to push, Steady day, Recovery day or Higher recent activity.
What this guide covers.
How the app handles this.
What this can look like in the app.
Example: HRV 7 ms below your average, resting heart rate 3 bpm above it and sleep 41 minutes short, so readiness reads lower than usual.
ExampleConfidence rises when the same pattern repeats against your own baseline and drops when key signals are missing.
Try one small change, log it, then see whether the pattern repeats over the next week.
Example 1
Example: steps were above your average the same day. Movement and readiness are separate, so you see both.
Example 2
Example Quest: keep the next day light and compare your next readings.
