Managing diabetes starts with tracking your blood sugar every day.
Gly Log is a blood sugar tracking app that makes it easy to log your glucose, meals, weight, and daily habits — and see how they change over time.
No complicated device pairing, no tedious setup. Sign in with Google, Apple, or start right away as a guest.
■ Simple blood sugar logging for diabetes care
Record your glucose readings by context: fasting, before meals, 1 hour after meals, 2 hours after meals, or at bedtime.
Add lifestyle tags like exercise, medication, and lack of sleep — plus notes — so you can look back and understand what moved your numbers.
■ Blood sugar and weight, together in one app
No need to juggle multiple apps for glucose and weight.
See your latest readings on the home screen, and set a target glucose range and goal weight that fit you.
■ See your trends and progress
Track how your blood sugar and weight change over 7 days, 30 days, 90 days, or a full year.
Average glucose, highs and lows, and your target range — all in one clear chart.
The more you log, the better you can see how your diabetes management is going.
■ A food database of 100,000+ items
Search from over 100,000 foods to log what you ate and how much.
Check nutrition facts — calories, carbs, sugars, protein, and fat — along with a glucose burden grade (Low · Medium · High) for each food, provided as reference information.
Log meals alongside your glucose readings to see which foods affect your blood sugar.
■ Export your records as a PDF report
Turn any period of glucose, weight, and meal records — with charts and notes — into a PDF report.
Perfect for organizing your numbers before a doctor's visit or sharing with your care team.
■ Start in seconds, no setup required
No glucose meter pairing or complicated device setup — just enter the readings you've measured.
Supports Google Sign-In, Apple Sign-In, and guest mode.

Gly Log is a reference tool to support diabetes management and personal health records.
It does not measure blood sugar with your phone or diagnose any medical condition, and it is not a medical device, healthcare provider, or emergency service. Always consult a medical professional for decisions about treatment, medication, or your health.
