GPT Food Cam is a free iPhone application designed to simplify food logging and calorie counting. Upon opening the app, users are greeted with a camera interface, allowing them to quickly capture images of their meals. The app utilizes AI technology to estimate the calorie range of the meal, encouraging users to log their food intake effortlessly. Additionally, a widget can be added to the home screen, providing reminders of daily calorie consumption.

The app was developed with a focus on fostering healthy habits rather than just tracking calories and macros. While it may not include extensive features found in paid applications, GPT Food Cam prioritizes ease of use and accessibility. The occasional advertisement in the food photo feed helps cover operational costs, making this a practical choice for users seeking a straightforward approach to food logging.
