Blood Glucose Log
A glucose reading on its own says little; a reading next to what you ate, what you dosed, what you did and how you felt says a lot. Log all of it in your meter's own units, plus any target range your care team set for you. Export the whole history for your next diabetes appointment. No targets, bands or thresholds are built in — those are your clinician's to set.

Frequently asked
Where is my data stored?
Only on this device, in your browser. Nothing is ever uploaded — export to CSV/JSON to back it up, print it, or bring it to an appointment.
Does this tell me if a reading is normal?
No. It is a logbook, not a medical device or an opinion. It records exactly what you entered so you can show your clinician a real history — what counts as normal for you is theirs to say.
My meter and my CGM disagree — which do I log?
Log both as separate rows and name the device in the device field, so whoever reads the log knows where each number came from.
