Stop doing glucose unit maths in your head.
Whether you manage diabetes, care for someone who does, or work in healthcare — GlucoConvert is the fast, beautiful reference tool that converts either way between mmol/L and mg/dL instantly.
THE CHART
Scroll through every reading from 1.0 to 33.3 mmol/L in 0.1 increments, with the mg/dL equivalent (18-600 mg/dL) right beside it. Colour-coded by zone — Low (red), Target (green), High (yellow), Very High (amber) — so you always know at a glance where any reading sits. Type any number in the search bar and jump straight to it, in either unit.
THE CALCULATOR
Type any reading and convert it instantly, in both directions. mmol/L to mg/dL or mg/dL to mmol/L. The result shows the zone colour so you always have context.
PERSONALISE IT
Set your own target range thresholds — because everyone's numbers are different. Adjust text size (all the way up to Maximum for vision-impaired users), switch between light and dark mode, and customise zone colours.
APPLE WATCH — Premium ($2.99 paid once)
Scroll the full conversion chart directly from your wrist using the Digital Crown. Turn it and watch the readings flow — no tapping, no typing. The last reading you looked up stays on your watch face as a complication.
FREE, FOREVER. NO ADS.
GlucoConvert is completely free. No ads, no subscription, no nag screens. The Apple Watch feature is a one-time $2.99 upgrade. If you love the app, there's a tip jar.
DESIGNED FOR REAL PEOPLE
Whether you're a Type 1 or Type 2 diabetic, a parent managing a child's blood sugar, a carer, a nurse, or a doctor working across both unit systems — GlucoConvert was made for you.
GlucoConvert is a unit conversion reference tool only. It is not a medical device and does not provide medical advice. Always consult your healthcare team before making treatment decisions.
