FoodCa

FoodCa is a calorie and diet tracking app for iPhone from an individual developer, listed as FoodCa-AI Diet Tracking. Instead of searching a food list, the user describes a meal in everyday speech or takes a photo of it, and AI works out the nutrition. FoodCa is built for people counting calories and for those following special diets, and it is also aimed at health management professionals.

A user can log a meal with a plain description such as a fist-sized portion of rice or a big bite of watermelon. A large text model tuned for breaking food down estimates the ingredients and their weights, then pulls nutritional values from a food nutrition database and shows the result. Entries are recorded with a single click, and charts summarize what was eaten.

Version 2.0 added photo recognition, customizable diet reminders and a personal food database. FoodCa sends diet alerts for Low FODMAP, Low GI, Low Purine, anti-inflammatory, ketogenic and gluten-free diets. An AI nutritionist comments on each day's food intake. The app shows no ads and has no community, store or courses, and the developer says data is stored only in iCloud. The developer built it while losing weight through a daily calorie deficit.

FoodCa is free to download, with Pro sold as a month for $1.99, a whole year for $9.99 or Lifetime Pro for $39.99. It runs on iPhone with iOS 16.6 or later and on Macs with an M1 chip and macOS 13.5, though it is not verified for macOS. The interface is in English, Simplified Chinese and Traditional Chinese. The developer does not collect any data from the app, and its advice carries a medical disclaimer.
