Your glucose, hour by hour

Show me my average daily glucose trend

Averaged over 69 days of FreeStyle Libre 3 readings, Jan 1, 2024 – Nov 1, 2024. These readings are from 2024. Each dot is that hour's average across all of them. The bar through each dot shows how much that average might shift with a different set of days. Shorter bar, surer number.

What do you want to know next?

Each one runs on your own export. What you asked is written down with today's date before anything is computed, so the question stays separate from the answer.

Is it getting better or worse?

The same readings by date instead of by hour, and a straight answer: going up, going down, or holding steady.

Uses only the export you already sent. It checks the dull explanations first — whether you simply wore it less in one stretch, whether new sensors line up with the change, and whether the change beats your normal day-to-day wobble.

Did the change I made work?

Pick a date you changed something — a supplement, a medication, a new routine — and get the before and after.

Needs one date from you. Before calling anything real, it checks whether a shift that size also shows up on dates when nothing changed.

What is causing my spikes?

Two answers, and they are not the same size. From the readings alone you get WHEN you spike: every rise above your own baseline, how high, how long, and which clock times it keeps happening at.

Naming the cause needs something logged beside the glucose. Tell us what you already track and we will use it; anything you don't track yet takes about two weeks of logging first.

Partly ready · the spikes now, the causes once something is logged

Something else?

Write the question in your own words. If your data can answer it, you get a page like this one. If it cannot, you get a straight explanation of what is missing.
