Net Carbs, surfaced first
Total carbohydrates minus dietary fiber — the number that actually moves blood sugar. Shown on every scan, not buried three taps deep.

Watch the short cut ↓I. The problem
Twelve grams of sugar means nothing without knowing it is twelve grams on top of today's thirty-eight.
II. Three movements
02
Estimated Glycemic Load
Net Carbs × estimated GI ÷ 100, classified low / medium / high. Tap to see the formula, the category source, and the honest "this is an estimate" disclaimer.
03
Your daily carb budget
130 g default for diabetic profiles — or whatever number your endocrinologist gave you. The dashboard tracks today's running total against that line.
III. Built around you
Set the number your endocrinologist gave you
Not a database. A cap — yours.
Generic scoring apps will tell you a granola bar has 22 g of net carbs. They will not tell you that you have already used 108 g of your 130 g daily ceiling, or that this is the third "small" carb of the morning.
NutriScan asks for your daily Net Carbs cap, Sugar cap, Sodium cap, and Calorie target during setup. Every scan is judged in that context. The score on screen is yours, not the average of a database.

IV. Principles
01
A score should be honest before it is friendly.
02
Personalization is the product. Generic averages belong on the back of the box.
03
A nutrition app should respect a supermarket's pace — three seconds, not three minutes.
04
No dark patterns. No streaks engineered to guilt you back in.
05
Your scan history lives on your phone first, ours second.
V. Where it shines
Made for the people already reading the back of the package
Four quiet moments NutriScan was made for.
The newly diagnosed
Three months to bring A1C down.
Net carbs cap set with your endocrinologist, every scan judged against that line — not a generic 50 g sugar default that nobody at the appointment mentioned.
The A1C countdown
Five weeks until the next blood test.
A running daily Net Carbs total on the dashboard. You can see whether the trajectory is on the side of "labs will look better" before the lab tells you.
The post-meal spike
Which carb did that to me?
Tap any scan to see its Glycemic Load · estimated tier · category source. The pattern across your week tells you which packaged foods actually move your numbers.
The grocery aisle
Three competing yogurts. Thirty seconds.
Net Carbs side-by-side. GL · est. side-by-side. The one with 4 g net carbs and a low-GL tier wins without a fight or a Google search.

VI. A note from the maker
A short note
Built in a kitchen, not a board room.
I started NutriScan after a year of staring at the back of cereal boxes for someone in my family who had just been diagnosed prediabetic. The information was right there — sugar, fiber, sodium, serving size — but it took a minute and a calculator to actually make sense of it.
A minute is a long time in a supermarket. NutriScan is what I wish I had then. It is a small app made with care, and it will stay that way.

VII. Final notes
A few things people ask
Quietly answered.
- Is the Glycemic Load measured or estimated?
- Estimated. NutriScan classifies each scanned product into one of ~60 food categories (white bread, sugar-sweetened soda, dark chocolate, etc.) and uses the published mid-range GI for that category. The modal shows the exact category and GI used, with an "estimate · category-based" disclaimer. It is a directional signal, not a lab result.
- Will it replace my CGM or glucose meter?
- No. NutriScan is a label-reading and pre-purchase tool. It is upstream of the meter — it helps you decide what to put in the basket, not interpret what already happened.
- Does it work for Type 1, Type 2, and prediabetes?
- Yes. You set the daily Net Carbs cap yourself (default 130 g for the diabetic profile), so it adapts to whatever number your team gave you — strict low-carb, ADA-style flexible, or anything in between.
- How is my data handled?
- Scans live on your phone first. Anything sent to our servers is only what is required for the OCR step. Nothing is sold, nothing is used for advertising.
- Is it free?
- Yes. Scan, score, the daily Net Carbs budget, and Glycemic Load estimates are all free. A small subscription unlocks long-term history and deeper personalization, if you ever want it.
