Fitfelo

Fitfelo is a mobile nutrition tracker built around a single bet: logging food should take seconds, not minutes. Users photograph a meal, type a quick description, or scan a barcode, and the app returns a structured breakdown of calories and macros ready to confirm and save — no manual database searching or portion guesswork required.

The app is a monorepo split between an Expo / React Native client and an Express + TypeScript backend on Supabase. All AI-facing work — photo analysis, label scanning, and free-text meal parsing — routes through a single service that enforces a JSON-schema response, sanitises hallucinated or non-food results, and logs token usage and cost per call, so the AI surface area stays small and auditable as features are added.

Currently in active development, with attention going into the details that make estimates trustworthy: distinguishing a nutrient amount from a food weight in free-text parsing, never inferring ingredients the user didn’t mention, and keeping day-level target adjustments separate from a user’s permanent goals so a one-off recalculation never overwrites long-term intent.
