What is Cal AI?

Cal AI is a mobile app for logging what you eat with the help of AI. A meal can be recorded in three ways: by taking a picture of it, by scanning a product barcode, or by describing it in words. For photos, the app uses the phone's depth sensor to gauge the volume of food and then estimates calories, protein, carbohydrates and fat. Users can also save their own foods and recipes. Cal AI connects to Apple Health on iPhone and Google Fit on Android, so steps and exercise appear alongside food data. The app is distributed through the App Store and Google Play and is sold as a subscription with a three-day trial. Its FAQ puts scan accuracy at roughly 80 percent and recommends bright lighting and a sharp, close photo. A dark mode is included.

Key Features

Photo Logging

Estimates the calories and macronutrients of a meal from a single picture, using the depth sensor to judge portion size.

Barcode Scanning

Reads a packaged product's barcode to pull its nutrition details into your log.

Text Description

Lets you type what you ate when a photo or barcode is not practical.

Macro Breakdown

Totals calories, protein, carbs and fat automatically so no manual arithmetic is needed.

Custom Foods and Recipes

Stores your own foods and recipes for quicker repeat logging.
