Food Technology is an app that integrates nutritional intake and weight management, focusing on addressing three major pain points in modern dietary choices: uncertainty about what constitutes healthy eating, difficulty in maintaining a healthy diet, and ineffective results due to a lack of professional guidance. Unlike traditional recipe apps that only provide standardized recipes, Food Technology enables users to achieve diversified food recognition through IoT devices—supporting both photo-based identification and barcode scanning for quick access to food names and nutritional information. The app offers flexible calorie goal settings, personalized fitness assessment reports, accurate exercise calorie calculations, and intake record retention. By leveraging IoT technology, it delivers an intelligent health management experience with interconnected data, convenient operation, and efficient battery life, helping users shift from passive dietary trends to active, science-based health control. Ultimately, it enables users to achieve multidimensional health goals such as weight management and nutritional balance.
