Log meter readings, context and notes. Review dated history and export data.
Blood Glucose is a manual journal for readings from your own glucose meter. The phone does not measure glucose.
LOG WHAT YOU KNOW
Enter a value in mmol/L or mg/dL and record when you measured it. Context starts as Unspecified. Choose Fasting, Before meal, After meal or Bedtime when useful, and add an optional note. Saved entries keep their original value, unit and chosen context. Correct or delete an entry when needed.
REVIEW YOUR ENTRIES
Filter History by the last 7 days, 30 days or all entries, and by context. See the selected readings and their average. Dated chart points use real measurement-time spacing and show the latest 14 selected entries; gaps mean no entry was recorded. Mixed units are converted only for the chart and average. Original values and units remain visible in the list and exports. There are no clinical targets or high/low labels.
YOUR DATA AND RECOVERY
• Readings and notes are stored on this device; no account is required
• Export the selected history as CSV, including original values, units, contexts, notes and timestamps
• Export a lossless JSON backup of all readings from Settings, and import it later to merge or replace your local journal
• Older Blood Glucose JSON backups remain readable
• Android may back up the journal to your Google account when device backup is enabled and your device has a screen lock; Google controls when backups run
FREE WITH A SIMPLE UPGRADE
Logging, history, charts and file export/import are free. Advertising supports the app. A one-time purchase removes ads permanently; there is no subscription.
Blood Glucose is not a medical device. It records the values you enter and does not diagnose, recommend treatment or give medical advice.
