Vision-based meal analysis — photograph your plate and AI estimates calories, protein, carbs, and fat
Text-based logging — describe what you ate in natural language for quick entry
Macro dashboard — daily/weekly tracking of calories, protein, carbs, fat, and fiber
AI workout plans — personalized exercise routines generated based on your goals and fitness level
Check-in system — periodic progress reviews with AI-powered insights

Technical Highlights

Rails 8.1 with RubyLLM for multi-modal AI (text + vision). Active Storage for meal photos. Hotwire frontend with Stimulus controllers. Solid Queue for background AI processing. Tailwind CSS for the mobile-friendly interface.
