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.
Start today: download GlycoGuardian and log your first reading in seconds.
