Fud AI

Fud AI is an open-source AI calorie tracker for people who want faster food logging without manually searching every item. You can log meals from food photos, nutrition labels, text, or voice. The app estimates calories, macros, grams, and serving units like slices, pieces, cups, and ml, then lets you review everything before saving. It supports BYOK, so technical users can bring their own Gemini, OpenAI-compatible, OpenRouter, Anthropic, or Ollama setup. On iOS, Fud AI Plus is available for users who want no-key AI access. Built for iOS and Android with Apple Health, Health Connect, AI Coach, widgets, custom themes, and privacy-first local food logging.
