## Photo-Based Nutrition Tracking with LLMs A developer has launched Flog, a free iOS application that allows users to monitor their food intake through photographs. The app uses Large Language Models (LLMs) to analyze images and estimate the portions and nutrients present in the food. ## Features and Privacy Flog integrates with Apple Health and offers the ability to use local LLM models, which can be run directly on the device or via LM Studio, for enhanced privacy. The application is free and does not include any form of monetization. The developer emphasizes that by using local LLM models, user data never leaves the device. ## How it Works The usage flow is simple: take a picture of the food, and the app, through image analysis and the aid of LLMs, provides an estimate of the nutritional values. The app supports Gemini 3.0 Flash via an OpenRouter key. A free "cloud" service is also available for quick testing, but the developer recommends not overloading it.
