Built by a T1, for anyone tired of counting carbs the hard way.

I was diagnosed Type 1 at 7. 33 years later, counting carbs has become an unwelcome chore. Every meal, every snack, every coffee that might have syrup in it.

CarbZen is my answer to diabetic fatigue. I wanted accuracy, but I didn't want the hassle that came with it. I didn't want to keep guessing the grams. I also didn't want to type my dinner into another food log, scroll a database, and pick the entry that looked closest. I just wanted a number, fast, without extra nonsense in the way.

Snap the plate. Get a carb count verified against USDA in three seconds. Show my endo the data when I see them. No food diary. No account. Just the carbs.

Chad · Founder · Type 1 since age 7

Quietly working for the people who tested it.

CarbZen is new on the App Store and Google Play. Here's what TestFlight users said while we were building it.

I was able to easily figure out what the carbs were in pretty much any meal I was having. I never needed to describe anything, it seemed to always figure it out, even with a lot of components on the dish. My control has been better with the help of CarbZen.

Diabetic, TestFlight beta Daily user · 2026

Fast to find the carbs and macros in anything I have got in front of me. Much easier for me to make good decisions on my keto diet.

Common questions.

Chad built CarbZen. He's been Type 1 since he was a kid. He counted carbs for every meal in this app while writing the code. The Doctor PDF Export exists because he wanted to print something for his own endo. If you want to verify, the App Store and Google Play listings show the same founder name as the support email.

Carb Manager is great if you want a full food diary, an account, a feed, weight loss programs, and a $99/year subscription. MyFitnessPal is built around calorie counting and weight loss, not carb counting. CarbZen does one thing: snap a photo, get the carbs in 3 seconds, cross-checked against USDA. No diary. No account.

Every AI estimate is cross-checked against the USDA FoodData Central database, and you can edit any value before saving, you stay in control. Treat any estimate, from an app, a menu, or a nutrition label, as a starting point, and talk to your care team about anything health related. CarbZen isn't a medical device.

AI estimates are cross-checked against the USDA FoodData Central database on every scan. You can edit any value if you know better, you stay in control. Treat the number as a starting point you can correct against your CGM.

Yes. CarbZen identifies multiple items on a plate and gives you a per-item breakdown, that's the whole point. Barcode scanners fail at restaurants. Cameras don't.
