Record glucose readings in mmol/L with context, and flag them against the target range your own doctor set — plus a time-in-range summary and CSV export. Saves in your browser. Free.
Targets are individual — enter the range your doctor or diabetes educator gave you, and readings are flagged against it.

⚕️ This is a record-keeping tool, not medical advice. It deliberately doesn't define "normal" — glucose targets vary by person, condition and treatment, so it flags readings only against the range your own doctor set. If you have symptoms of a severe low or your readings alarm you, follow your management plan and seek medical help.
A list of numbers without context is nearly useless to your doctor; a log with time, context, and notes is how patterns get found — the post-breakfast spikes, the afternoon lows after exercise, the effect of a medication change. That's why context is a required habit here, and why the time-in-range percentage is the headline stat: it's increasingly how clinicians summarise control between HbA1c tests. Australia uses mmol/L (US sites often show mg/dL — divide those by 18 to convert).
Bring the CSV to appointments instead of a shoebox of scraps. Food is half the picture, so the Meal Planner pairs naturally, and steady routines from the Habit Tracker — walking after meals is a classic — often show up in the readings within weeks.
Why doesn't the tool tell me what a normal reading is?
Because targets genuinely differ — by diagnosis, medication, age, pregnancy, and hypo risk. Publishing one "normal" range would be wrong for many readers, so the tool flags readings only against the range your own doctor gave you.
What is time in range?
The percentage of your readings falling inside your target range — shown above your table once a range is set. It's a simple, increasingly standard way to see overall control between HbA1c checks.
mmol/L or mg/dL?
Australia (and most of the world) uses mmol/L, which this log expects. If you see mg/dL figures online, divide by 18 — e.g. 126 mg/dL equals 7.0 mmol/L.
How often should I test?
Exactly as your doctor or diabetes educator prescribed — it varies enormously by treatment. Whatever the schedule, consistent context labels are what turn the numbers into insight.
Is my health data private?
Yes — readings stay in this browser on this device and are never uploaded. The CSV export is both your doctor copy and your backup.
