GlycoGuardian: Glucose Log

Twenty seconds per entry. A clear picture of your blood sugar.

GlycoGuardian is a simple, focused blood glucose diary: log your readings, carbs, exercise and weight, see everything organized on the "Today" dashboard, and follow your trends week after week — anonymous, private and clutter-free.

WHAT'S INSIDE Fast logging: glucose (mg/dL), carbs, exercise and weight, with date, time and an optional note Context tags: fasting, before/after meal, breakfast, lunch, dinner, snack, insulin and bedtime Custom target range: set your own limits and instantly see whether each reading is below, within or above range "Today" dashboard: last reading, daily average, time in range, 7-day chart and your latest entries at a glance Logging streak: see how many days in a row you have been keeping your diary ⏰ Measurement reminders: morning, lunch, dinner and bedtime — you choose which ones to enable History with trends: 7-day and 30-day charts with the period average Weekly report: average, lowest and highest glucose, best and worst day, classification breakdown and time in range Export as PDF: turn the weekly report into a PDF to bring to your doctor's appointment Optional cloud backup: link a Google account so your readings survive switching phones In 5 languages: English, Portuguese, Spanish, French and German

BUILT FOR ROUTINE People who track glucose do it several times a day — so every screen is designed to be quick: open, log, done. Gentle reminders help you keep the habit, and your streak shows the progress. Even the empty states guide you: whenever a chart has no data yet, the app tells you exactly what to log to bring it to life.

YOUR DATA IS YOURS No mandatory sign-up: by default, all readings are stored only on your device, anonymously. If you want, turn on cloud backup by linking a Google account. You can erase all data — on the device and in the cloud — at any time, right in Settings.

IMPORTANT NOTICE GlycoGuardian is a personal diary and not a medical device. It does not provide medical advice, diagnosis or treatment and does not replace professional care. Always talk to your doctor before making decisions about your health or treatment.
