Tools for managing gestational diabetes
A gestational diabetes diagnosis usually arrives with a glucose meter, a leaflet and a four-week wait for the dietitian. These tools answer the questions you have tonight.
Each one takes a handful of numbers you already know and gives you something you can act on immediately — no account, no app install, and nothing you enter is stored. The maths behind them comes from published gestational diabetes nutrition guidance, and every tool shows its working so you can take it to your care team.
Available tools
Gestational Diabetes Blood Sugar Checker
Is this reading normal, or should I call someone?
Type in the number on your meter, say when you took it, and get an instant in-range, borderline or call-your-team verdict — using the targets from your own country, in your own units.
Gestational Diabetes Meal Plan Calculator
How many carbs a day, and how do I split them across meals?
Turns your height, weight and how far along you are into a daily carb budget, a calorie target, and a gram-by-gram split across three meals and three snacks.
Blood Sugar Unit Converter: mg/dL ↔ mmol/L ↔ g/L
What is my number in the other unit?
Type a blood sugar reading in whichever unit you have and get it in the other two instantly — plus what that number means in gestational diabetes, which most converters never tell you.
Which tool do you need?
What each tool answers, how long it takes, and where its numbers come from.
| Tool | Answers | Takes | Based on |
|---|---|---|---|
| Gestational Diabetes Blood Sugar Checker | Is this reading normal, or should I call someone? | About 15 seconds | Self-monitoring targets published by ADA/ACOG, NICE, Diabetes Canada, ADIPS, GEDE, CNGOF and DSOG |
| Gestational Diabetes Meal Plan Calculator | How many carbs a day, and how do I split them across meals? | About 1 minute | Jovanovic-Peterson energy estimates, IOM trimester intakes, ADA and ACOG carbohydrate guidance |
| Blood Sugar Unit Converter: mg/dL ↔ mmol/L ↔ g/L | What is my number in the other unit? | About 5 seconds | The standard glucose conversion factor of 18.0182, with target values from ADA/ACOG, NICE, Diabetes Canada, ADIPS, GEDE, CNGOF and DSOG |
Why you can use these with confidence
Built on published guidance
The calculations follow standard gestational diabetes nutrition methods, and each tool lists the sources it draws on.
Safety limits built in
Where the maths would produce something unsafe in pregnancy — too few calories, too little carbohydrate — the tool clamps it and tells you it did.
Nothing is stored
Everything runs in your browser. No account, no database, and your measurements never leave the page unless you choose to share a result.
Questions about these tools
Are these tools free?
Yes, completely. There is no account to create, no trial, and no card. The SugarCurve app is a paid product, but these calculators work fully without it.
Do these replace advice from my doctor or dietitian?
No. They give you a sensible starting structure based on general gestational diabetes guidelines, which is genuinely useful in the gap between diagnosis and your first dietitian appointment. Your own glucose readings and your care team's advice always take priority.
Is my data stored anywhere?
No. The calculations happen in your browser and nothing you type is saved to our systems. If you share a result, the numbers travel in the link itself — we still keep no copy.
Can I use these if I have type 1 or type 2 diabetes in pregnancy?
These tools are built specifically around gestational diabetes, which is usually managed with diet first. If you were diabetic before pregnancy, especially on insulin, your targets and carb distribution are set by your specialist team and you should follow those instead.

These tools provide general information about nutrition in gestational diabetes. They are not a medical device and do not provide a diagnosis or treatment plan. Always follow the guidance of the midwife, doctor or dietitian looking after your pregnancy.
