What's New in CarbZen

1.4.0

July 13, 2026

Scan nutrition labels and full recipes for carbs per serving. Pick a photo from your library to scan. Keep using the app while your scan finishes in the background. Your zen week grows into a year long journey with milestones and a trophy shelf. Set daily carb, protein, and fat goals and see them as rings on Apple Watch. Add Lock Screen and Home Screen widgets for carbs at a glance. Retake the photo or describe the meal when a scan can't be read. History is easier to read at larger text sizes, and scanning uses less battery.

User reviews

Not useful

This app only counts carbs.

I don’t understand the point of this since a food tracker like LooseIt will keep track of carbs and a lot more, and does a better job of recognizing food.

CarbZen thought a chicken breast was salmon.

Response from developer

Thanks for taking the time to write this. I’m sorry CarbZen wasn’t the right fit. CarbZen does track more than carbs, including protein, fat, and calories, though I understand that may not have been clear enough. Carbs are prioritized because the app was built to make carb counting faster and less frustrating, and the full macro breakdown is included with Pro. You’re also right that food recognition is not always correct. Every item can be corrected, and that feedback helps me keep improving CarbZen. I’m an independent developer, so feedback like this is genuinely helpful. If you’re open to sharing more about what felt missing or confusing, please reach out anytime at support@carbzen.app.

Quick Results

CarbZen gave me quick and accurate results when I was out to eat on my Khao Soi. I was surprised.

Response from developer

Thank you so much for the review. I’m glad the app helped. Reach out if you have any suggestions to make it better.

FAQ

How does CarbZen estimate carb counts?

CarbZen uses AI to estimate the carbohydrate content of food items from a photo of your meal. It then cross-references these estimates with data from the USDA FoodData Central for enhanced accuracy. You can see both the AI estimate and the USDA value and choose the one that best fits your meal.

What are the free features of CarbZen?

The free version of CarbZen provides real carb counts on every scan, net carb calculations, and a breakdown of carbs per item. You also get to save your scan history and photos on your phone. After your first week, you receive 30 free scans per month.

What does CarbZen Pro offer?

CarbZen Pro unlocks additional features such as full macro breakdowns (protein, fat, fiber, calories) per item, clean PDF reports for healthcare providers, Apple Health sync, unlimited scans, daily carb goals, weekly trends, and meal notes. A free trial is available for eligible users.

Is CarbZen a medical device?

No, CarbZen is not a medical device. It provides carb estimates for general information only and does not replace a glucose monitor, a dietitian, or your care team. Always confirm meal and dosing decisions with your clinician.

How does CarbZen handle user privacy?

CarbZen does not require an account, email, or a food diary. Your scan history is saved locally on your phone with optional iCloud backup. Photos are sent securely for analysis and are not stored after the count is returned. Your data is never sold.

What is the subscription model for CarbZen Pro?

CarbZen Pro is an auto-renewing subscription available monthly or yearly, with a one-time lifetime purchase option. Payment is charged to your Apple ID upon purchase confirmation. Subscriptions can be managed or canceled in your Apple ID settings at least 24 hours before the current period ends.
