## What is Blood Sugar Tracker?

A blood sugar log built around real life, not perfect days.

If you live with diabetes, prediabetes or gestational diabetes, you already know the daily juggle of glucose readings, insulin doses, carbs and the questions your endocrinologist will ask next visit.
SugarLog is a calm diabetes journal that puts every number in one place, on this device, without turning your health into someone else's data point.
It is the quiet alternative to bloated tracker apps and scattered notes — a sugar tracker designed for people who want their blood sugar log to feel like a private notebook, not a social platform.
No account is required, nothing is uploaded to a third-party server, and the app does not sell, share or analyze your readings for advertising.
It works whether you fingerstick with a meter, glance at a glucose monitor, wear a CGM, or pair short-term sensor data with manual entries.

Every feature described below is unlocked only with an auto-renewable subscription purchased inside the app. New users receive a 3 day free trial; you may cancel anytime during the trial to avoid being charged.

Open the app and log a glucose reading in seconds, then add insulin, meal carbs, exercise, weight or blood pressure as the day unfolds.
Time in Range, GMI, average, standard deviation and an estimated HbA1c from a rolling 90-day eAG turn raw entries into the metrics your clinic actually uses on visit day.
Pattern detection surfaces dawn phenomenon, post-meal spikes and hypo clusters before they harden into a trend, and multi-period charts span today, this week, this month, 90 days and the full year.
Tags for fasting, pre-meal, post-meal, bedtime and sick days keep context attached to each value, so a glucose log is more than a column of numbers.

Apple Health two-way sync keeps glucose, insulin, carbs and weight aligned with your other health apps, while a built-in carb counter, food library and medication tracker keep daily logging fast.
The sugar diary side of the app records what you ate, how you felt and what you adjusted, so the next conversation with your doctor is grounded in real entries instead of memory.
Doctor-ready PDF reports share cleanly with your endocrinologist or diabetes educator, an Apple Watch app and Live Activity make logging glanceable, and reminders nudge you toward a fasting reading or a delayed dose without scolding.

The interface ships in 16 languages with full RTL support and App Lock via Face ID, Touch ID or passcode.
Home Screen and Lock Screen widgets keep your last reading and time in range visible, and the entire blood sugar log stays on this device.
Privacy is the default: no account, no cloud upload, no third-party analytics.
The app is suitable for type 1, type 2, gestational diabetes during pregnancy and prediabetes monitoring — and quiet enough to live with for years.

Unlock with Pro:
• Unlimited history beyond the free 30 days
• Doctor PDF report, advanced charts and pattern reports
• All Home Screen, Lock Screen and Apple Watch widgets
• Light, dark and 5 color themes plus premium icons
• Custom food library and full medication reminders
