One reading at a time — Glucose Diary is the simplest, most accurate way to track blood glucose for diabetes management and prevention. ▶ Record readings with their meal context Fasting · Pre-meal · 2h post-meal · Bedtime · Random — thresholds for "normal" differ by context, so each entry is auto-classified by when it was taken. ▶ Trend at a glance A smooth line chart visualizes your glucose over time, with target-range guides (70-180 mg/dL) that make trends easy to read. ▶ Estimated A1C (after 14+ days) Based on the ADA average-glucose-to-A1C conversion. A useful self-monitoring proxy between lab visits. ▶ Choose your classification standard Korean Diabetes Association (KDA) or American Diabetes Association (ADA) — match whichever your doctor uses. Your raw data is unchanged when you switch standards; only the labels are recomputed. ▶ Categories (auto-applied per meal context) • Severe low (under 54 mg/dL) • Low (54-69) • Normal — context-specific threshold • Pre-diabetic (IFG / IGT) • Diabetic • Severe high (300 or higher) ▶ Activity, feeling, and medication tags After exercise · After alcohol · Traveling · Tired · Stressed · Sick · After insulin — common contexts are one tap; create your own tags as needed. ▶ Calendar view Month calendar with category-colored dots — see at a glance which days you logged and how each reading fell. ▶ Reminders Up to 3 daily measurement reminders at the times and weekdays you choose. Scheduled locally on the device — no internet required. ▶ Export and backup CSV export to share with your doctor; full JSON backup and restore for moving between phones. ▶ 100% on-device — no internet, no account Every reading is stored in a local SQLite database. Nothing leaves the device. No sign-up required. Your health data stays yours. ▶ Korean and English Auto-detects from system locale, or pick manually in Settings. Dark mode supported. --- Note — This app is a self-monitoring diary, not a medical device.
