Fud AI in one post: open source, BYOK, snap-a-photo logging

Wrapping the first build-in-public run for Fud AI. The short version:

• Native iOS + Android calorie + nutrition tracker
• Snap a photo -> estimated calories + macros (plus barcode, label, photo library, voice, type, manual, saved meals, copy-day)
• BYOK: your own Gemini / OpenRouter key, or optional Fud AI Plus
• AI Coach that reads your logs, progress + weight + body-fat tracking, BMR your way
• Open source, MIT

If you build, the code's the most interesting part. Tear it apart: https://github.com/apoorvdarshan/fud-ai
