Enter your Nightscout site, pick a period, and get your numbers — standard Time in Range plus your own optimal ranges.
Just the address is fine — with or without the https:// part.
If your site opens for reading without logging in, leave this blank.
On your Nightscout site: open the menu → Admin Tools → under
"Subjects – People, Devices, etc.", use a subject with the readable role
(or add one — name it reader, role readable). The token is the
full string that looks like reader-1a2b3c4d5e6f7a8b — the name, the dash,
and the letters and numbers after it. The API secret (your site's master password) will
not work here — and that's on purpose: a read-only token is the safer thing to use.
Ctrl+S (Mac: Cmd+S) and save the file.
On a phone: use the browser menu → Share or Save.The clinical bands your care team uses — the same yardstick for everyone, so the numbers are comparable.
Your own bands, measured against the same data. Each range is counted on its own — overlap is fine.
Your ranges are saved in your browser only, so they'll be here next time — on this device.
