About Cal.AI

What the app is, who publishes it, how it estimates nutrition, and how we research the articles on this site.

Last updated:

In one paragraph Cal.AI is an AI calorie counter for iPhone, Apple Watch and Android. You photograph a meal, scan a barcode or search a food, and the app logs calories, protein, carbs and fat against a daily target built from your goal and body stats. It is free to download; Cal.AI Pro is an optional subscription. Estimates are approximate and Cal.AI is not medical advice.

What Cal.AI does

Cal.AI runs on iOS 15 or later, watchOS and Android 8.0 or later, in English, German, French, Italian, Spanish, Portuguese, Japanese, Korean, Vietnamese and Arabic. Prices and what is included in Pro are on the pricing page; common questions are answered in the FAQ.

Who makes Cal.AI

On the App Store, Cal.AI (listed as "Cal.AI - Calorie Tracker", first released in February 2025) is published by BYTEMEDIA PTE. LTD. The Android app is on Google Play under the package name com.moyo.calories. This website, cal.moonga.me, is the app's official site.

How accurate are the estimates?

A photo cannot show oil absorbed during cooking, sugar dissolved in a sauce or food hidden under the top layer, so photo estimates are approximate. They are closest with good light, the whole plate in frame and the camera above the food. Barcode scans of packaged foods use label values, which are more reliable than any photo estimate. We explain the error sources, and how to keep them small, in How accurate is AI calorie counting from a photo?

How we research and write the blog

The Cal.AI blog covers food calories, calorie tracking, nutrition basics and weight-loss math. Every article follows the same rules:

  1. Sources first. Claims and numbers come from primary or institutional sources: peer-reviewed studies (PubMed, PMC and the journals themselves), USDA FoodData Central, the NIH, FDA, CDC, WHO, NHS and the Dietary Guidelines for Americans. Each article lists its sources at the end, with links.
  2. Food numbers from USDA. "Calories in" pages use USDA FoodData Central (SR Legacy) values per 100 g and USDA portion weights. Per-serving figures are calculated from those values, and each page names the exact USDA entry and FDC ID it uses.
  3. An answer up front. Each article opens with a short, direct answer, then shows the method, the worked numbers and the caveats.
  4. No invented data. We do not publish made-up statistics, testimonials or reviews. Where the evidence is mixed, the article says so.
  5. The app where it helps. Articles explain the method first. Where Cal.AI is relevant, we say how to do it in the app and what its limits are.

Articles are general nutrition-tracking guidance, not medical advice. If you are pregnant, have a medical condition, take medication that affects appetite or weight, or have a history of disordered eating, talk to a doctor or registered dietitian before changing how you eat.
