FitHub is an AI-powered calorie and macro tracking application designed to streamline the tracking process for users. Built by engineers from Microsoft AI, it allows users to quickly log their food intake by either snapping a photo, describing the food, or scanning a barcode. This innovative approach has reportedly led to a 90% reduction in the time needed for calorie tracking, making it a convenient option for individuals focused on their health and fitness goals.

The app features an extensive database to support food searches and provides AI-driven suggestions for tracking calories and macros. While the basic usage is free, advanced features like barcode scanning and photo recognition require a subscription. It is important to note that FitHub does not offer medical advice, and users are encouraged to consult professionals for medical dietary needs.
