Trends & Insights
How your averages and patterns are built.
Why do my trends take a few days to settle?
Glynce builds trends from your own data. In the first days there is simply not enough yet to be reliable.
Time in range, explained
Time in range is the share of readings inside your target range over a period. It is often more useful than a single average.
GMI vs A1C: what's the difference
GMI comes from your CGM average; lab A1C is a blood test. See how they differ, why they often don't match, and a simple mean-glucose to GMI example chart.
Average glucose and what it tells you
The mean of your readings over a period. Useful as a summary, but best read alongside time in range and variability.
Glucose variability and coefficient of variation
Two related measures of how much your glucose swings: standard deviation in your glucose unit, and coefficient of variation as a percentage.
