How to use

Track your glucose in 3 steps

1

Log each reading

After measuring your blood sugar, enter the value, select the timing (fasting, pre-meal, post-meal or bedtime) and add an optional note.

2

Review your trends

The chart shows your readings over 7, 14 or 30 days. Look for patterns — are post-meal readings consistently high? Is your fasting glucose creeping up?

3

Share with your doctor

Use the Export CSV button to download your log. Bring it to your next appointment so your doctor can review your glucose patterns and adjust your treatment if needed.
