Sugar Monitor: Glucose Log

Sugar Monitor is a blood glucose diary that respects you. No subscription, no ads, no account, and nothing leaves your phone unless you ask it to.

Most diabetes apps put basic things behind a paywall — reminders, reports, even dark mode. Sugar Monitor gives you the whole app, free, and works completely offline.


LOG A READING IN SECONDS
• Type the number, tap when you measured it, done
• Colour-coded the moment you type: low, in range, high, very high
• Meal tags built into the entry screen — fasting, before meal, after meal, bedtime — not hidden behind an extra step
• Optional note for what you ate, how you felt, or activity


RANGES THAT ACTUALLY MAKE SENSE
Most apps flag one number for every situation. Sugar Monitor knows 150 mg/dL means something different before a meal than an hour after one, and judges each reading against the right target.


SEE YOUR REAL TRENDS
• 14-day average and estimated HbA1c
• Time in range, at a glance
• A clean glucose chart with your target band drawn in
• Daily diary with filters, so you can find any reading fast


mg/dL OR mmol/L
Switch any time. Readings are stored in one canonical unit and converted for display, so your history never gets corrupted by changing the setting.


DARK MODE FROM DAY ONE
A proper dark theme, not an afterthought. Easy on the eyes for a 3am check.


YOUR DATA, YOUR CONTROL
• Everything is stored on your device
• Automatic cloud backup is switched OFF — your readings are never silently copied to anyone's servers
• Export to a file whenever you want
• Optional Google Drive backup, into a private app folder only you control, and only if you choose to turn it on
• No account. No sign-up. No tracking. No ads.


BUILT FOR EVERY DAY
Fast to open, light on battery, small download, and it works with no signal.

IMPORTANT
Sugar Monitor is a personal logbook to help you record and understand your own readings. It is not a medical device and does not diagnose, treat, or give medical advice. The estimated HbA1c is a calculation from your average glucose, not a lab result. Always confirm with a blood test and follow the guidance of your doctor or diabetes care team.
