Maker here 👋 Fud AI is free & open source — privacy-first calorie + workout tracking with BYOK AI (optional hosted on iPhone). Would love feedback especially on: • multi-photo meal logging • workouts / exercise library • Coach answers with your real data App Store + Play + GitHub in the links. Happy to answer anything!
