01
Photograph the meal
Take or import a photo and get likely foods, portions and a carbohydrate estimate without pretending the camera is perfectly precise.
For people with diabetes who count carbs and use mealtime insulin
Photo the meal. See the carbs. See what they mean for your insulin.
SnapCarb is built especially for people with type 1 diabetes: take a meal photo, get a likely carbohydrate estimate, correct the food or portion, then see how the confirmed carbs convert using your own insulin-to-carb ratio.
Photo → carbs → your ratio → visible insulin conversion.
Why it matters
The hard part is not the formula. It is estimating the plate.
When you already know your own insulin-to-carb ratio, the frustrating part is often the meal in front of you: How many carbs are actually there? SnapCarb starts with the photo, helps estimate the meal, makes correction easy, and then shows the conversion using the settings you already use.
Built around real meals
Start with the plate in front of you.
Rice, potatoes, mixed dishes and real portions do not arrive with perfect labels. SnapCarb starts from what is actually on the plate, helps build an estimate, then lets you correct it before the numbers go any further.
What you get
From plate photo to a number you can actually use.
SnapCarb focuses on the mealtime workflow: estimate the carbs, correct the estimate, then translate the confirmed amount through your own configured settings.
02
Correct the carbs
Change the food, portion or carb amount before anything is converted. The estimate is a starting point, not a command.
03
Use your own ratio
Apply your configured insulin-to-carb ratio to the confirmed carbohydrate amount and show the carb-coverage calculation clearly.
04
Learn your usual meals
Remember recurring foods, plates, bowls and corrected portions so familiar meals become faster to estimate over time.
A simple example
52 g carbs. Your ratio is 1 unit per 10 g.
You photograph dinner. SnapCarb first estimates 58 g of carbohydrate. You correct one portion and confirm 52 g. With your own 1:10 insulin-to-carb ratio, the carb-coverage conversion is shown as 5.2 units.
That is the carbohydrate-coverage calculation. Other personal factors can affect the bolus you actually choose.

Quick answers
What SnapCarb does—and what stays with you.
Carb estimation should make the mealtime decision easier to understand, not hide it behind automation.
Is SnapCarb for type 1 diabetes?
That is the primary audience: people who count carbohydrates and use a personal mealtime insulin-to-carb ratio. The concept may also be useful to other people who need structured carb estimation.
Does it decide my insulin dose?
No. SnapCarb shows the carbohydrate estimate and the carb-coverage conversion using settings you configured. Current glucose, correction needs, active insulin and other personal factors can still affect the bolus you actually choose.
Does SnapCarb choose my insulin-to-carb ratio?
No. Your ratio is personal. SnapCarb uses the ratio you enter; it does not invent a universal ratio for you.
What if the photo estimate is wrong?
Correct it before using the number. The whole design assumes image estimates can be imperfect and makes correction part of the normal flow.
Can it remember my usual meals?
Yes. Recurring foods, bowls, plates and corrected portions can become a personal calibration library, making familiar meals faster to estimate over time.
Will the calculation be hidden behind AI?
No. Food recognition can assist with estimation, but the carb total, your settings and the arithmetic stay visible.
Mealtime, simplified
Know the carbs. See the conversion. You make the call.
SnapCarb is designed around the real type 1 diabetes mealtime workflow—not a generic calorie tracker with insulin bolted on afterward.
From plate photo to carb estimate to your own insulin ratio—without hiding the math.
