Track BSL / BGL readings before and after meals. Live chart, colour-coded, saves automatically.
⚠️ This is a self-monitoring tool only. It does not replace medical advice. Always discuss your readings with your GP or diabetes care team.
General guideline targets — your GP or diabetes educator will set personalised targets based on your age, medications, duration of diabetes, and other health conditions. These are not one-size-fits-all.
| When | No diabetes | Type 1 or 2 | Gestational |
|---|---|---|---|
| Fasting / before meals | 3.9–5.5 70–99 mg/dL | 4–7 72–126 mg/dL | <5.3 <95 mg/dL |
| 1 hour after meals | — | — | <7.8 <140 mg/dL |
| 2 hours after meals | <7.8 <140 mg/dL | <10 <180 mg/dL | <6.7 <120 mg/dL |
| Bedtime | — | 6–8 108–144 mg/dL | — |

Test before meals, 2 hours after the start of a meal, at bedtime, and occasionally at 2am if your GP advises. You don't need every time point every day — your GP or diabetes educator will tell you how often to test.
Readings save automatically to your device. Close and reopen the page and they will still be here. Use Clear All to start a new week.
Switch between mmol/L and mg/dL at any time — all readings convert automatically. Values are always stored in mmol/L internally.
BSL / BGL is a snapshot of your blood glucose right now — it varies throughout the day with meals, exercise, stress, and medication. This log tracks your day-to-day pattern.
HbA1c reflects your average blood glucose over the past 2–3 months. Target for most people with type 2 diabetes: below 7% (53 mmol/mol). Checked by a blood test at a pathology lab every 3–6 months. An HbA1c result cannot replace daily BSL monitoring.
mmol/L is the standard unit in Australia, New Zealand, the UK, and most of Europe. Your glucose meter, GP, and diabetes educator will use mmol/L.
mg/dL is used in the United States, Canada, Japan, and some other countries. If you have a US-purchased meter or are comparing with American guidelines, use mg/dL.
Conversion: mmol/L × 18.016 = mg/dL. This log converts automatically when you switch units.
This blood sugar log is a self-monitoring tool only. It is designed to help you record your readings and share a summary with your healthcare team. It does not diagnose diabetes or any other condition, and it does not replace medical advice, assessment, or treatment.
Blood sugar targets vary significantly between individuals depending on age, medications, duration of diabetes, risk of hypoglycaemia, and other health conditions. The target ranges shown are general guidelines — your GP, endocrinologist, or credentialled diabetes educator will set personalised targets for you. Always follow their advice over the general ranges shown here.
If you are experiencing symptoms of hypoglycaemia (shakiness, sweating, confusion, rapid heartbeat) or hyperglycaemia (excessive thirst, frequent urination, blurred vision), seek medical advice. In an emergency, call 000.
