Glucose Converter Log

Convert blood glucose between mg/dL and mmol/L instantly. Save readings, see your average, and share a report with your doctor. Built for people with diabetes, nurses, doctors, dietitians, and medical students.

The US uses mg/dL. Europe, Korea, Japan, and most of the world use mmol/L. When you read a medical paper, use an imported glucose meter, or travel abroad, you need the other unit — and you need it right now. This app gives it to you in one tap, then quietly turns into a tracker as you save each reading.

★ Why this app is different
• No sign up. No account. No cloud. 100% on your phone.
• Both units side by side — never lose context when you swap.
• Tap Save and you have a tracker. Skip it and stay a converter.
• Estimated HbA1c from your last 30 days — free, no Pro.
• Multilingual interface for global users.

★ Core features
• mg/dL ↔ mmol/L two-way conversion (factor 18.0182)
