A higher HRV is generally a good thing, but there are exceptions which the app picks up on. You want your HRV to gradually increase over time (weeks, months, years). If you have taken a few Morning Readiness readings, you know that your HRV can go up and down slightly from day to day. This is normal and generally healthy.
Grey: You see this indicator type on your first Morning Readiness reading (or if you haven’t taken a MR reading in a while). The grey indicator with a score of n/a shows that you need to establish a baseline of a few days to compare to before you can start receiving Morning Readiness scores, indicators, and recommendations.
