Frequently asked questions

No. The Insulin Fix Scanner is a web app, so it runs right in your phone or computer browser, with nothing to install from the App Store or Google Play. For an app-like experience you can add it to your home screen, so it opens full screen with its own icon.

On an iPhone, open insulinfixscanner.com in Safari, tap the Share icon at the bottom of the screen, then choose Add to Home Screen. On Android, open it in Chrome, tap the menu, and choose Install app or Add to Home Screen. After that it opens full screen from your home screen, just like a downloaded app.

Apple does not let any website show its own install button. On iPhone you add a web app to your home screen through Safari's Share menu instead. It takes two taps: Share, then Add to Home Screen.

No. Scoring a photo needs an internet connection, because the analysis runs on our servers, not on your phone. Your saved scans and diary load again whenever you are back online.

It is a single number from 0 to 100 that reflects how a food choice tends to affect your insulin, based on Karl Jacob's method from the book Fix Your Insulin. A higher score tends to mean a lower insulin load. It is not calories, not macros, and not a percentage. Just the one number, and one simple upgrade you can make.

Usually the difference is the buffer. The score weighs the whole plate, so the same carbohydrate can land in very different places depending on how much fiber, protein, and fat surround it. White rice on its own scores lower than the same rice topped with salmon and vegetables, because the protein and fat slow digestion and tend to lower the insulin demand.

Calorie counting treats every calorie the same and ignores hormones. Glycemic index ranks one food at a time. The Insulin Fix Score judges the whole meal as you eat it, including the protein, fat, and fiber that change how the carbohydrate behaves, and turns that into one number about insulin load, not energy.

Yes. On any result you can correct the read, which re-checks the same photo with your note and does not use another scan, or you can discard and retake. The score is an educated estimate from a photo, so a quick correction helps it match what is really on your plate.

Point your camera at a meal for your Insulin Fix Score and the one change worth making, your fridge to see what is helping and what to swap, a grocery cart or shelf to decide before you buy, or a restaurant menu for the best dishes to order. The app recognizes which is which. Fridge, cart, and menu scans are for guidance, so to keep your tracked average meaningful only meal scans count toward it.

On the Scanner plan and up, every scan is saved to a day-by-day timeline of what you scanned, the score it earned, and any notes you added, so you can see your week at a glance and spot patterns. On the Coach plan you can also log your weight and glucose readings, and a chart plots your average score against your weight over the last 30 days. Everything stays private to your account.

The Pattern Coach is the flagship Coach-plan feature. It reads your own recent data, your scores, your notes, the times you tend to eat, your weight and glucose, and gives you a short, personal coaching note in Karl's voice: what is genuinely working for you, the one habit worth focusing on next, and the research behind why it matters. It needs at least a few scored meals before it has enough to go on, and it is for education and encouragement, not medical advice.

Free gives you 20 scans to try, with your score on every one. Scanner adds unlimited scans, all scan types, your history, and your diary. Coach adds everything in Scanner plus the weight diary, glucose tracking, and the Pattern Coach.
