Primarily using key heart rate and heart rate variability (HRV) metrics, the Daily Readiness is a daily morning score that quantifies the user's ability (readiness) to handle the day’s challenges based on their body’s cumulative stress load and recovery status.
This insight automatically help users optimize their daily behavior to achieve better long-term results.
The Daily Readiness and insights require at least two days of data in order to be calculated. If it's the first day recording a daily reading, the output value for both of these insights will be null. See the input requirements and output table below for more details!
