GlucoDiary: Blood Sugar Log

GlucoDiary is a simple, free logbook that makes daily glucose tracking effortless. Log fasting and post-meal readings by time of day, see how meals, exercise, and medication affect your numbers, and hand your doctor a clean PDF report at your next visit — everything you need to manage your blood sugar, in one app.

No complicated setup. Large, easy-to-read text. Free to use.

Logging takes just a few taps

Record your blood sugar by time of day — fasting, before and after meals, at bedtime, and more. Meals, snacks, exercise, insulin and medication, weight: a few taps and your daily check-in is done. Works with both mg/dL and mmol/L.

Never miss a reading

Get reminders at the times you choose — fasting, breakfast, lunch, and dinner. Log a meal, and the app will remind you when it's time to take your post-meal reading. Even on busy days, you won't lose track of your routine.

The app does the math for you

Weekly and monthly averages, highs and lows, and time above your target range — all calculated automatically. Compare how your glucose changes after meals or exercise in clear, easy-to-read tables. Set your own target range, and staying on track gets a whole lot easier.

Share with your doctor or family in seconds

Turn your records into a PDF or image and share it right away. No more copying readings into a paper logbook before appointments. Keep your family in the loop, too — whether they live with you or far away.

Your health data stays private

All blood sugar data is stored encrypted. It is never shared without your consent — only you can access your records.
