FitNotFat

An Android food diary and workout log — Flutter client, NestJS and PostgreSQL backend, barcode lookup through Open Food Facts, self-hosted and invite-only.

A food diary built around the thing other trackers get wrong: recipes are entered by raw ingredients and then scaled by the cooked weight, so a portion of yesterday’s stew has honest numbers. Barcodes resolve through Open Food Facts with a local product cache, and simple workouts are logged alongside meals.

• Client: Flutter, Android first.
• API: NestJS with Prisma over PostgreSQL, migrations applied on deploy.
• Accounts: invite-only, JWT, tokens in the platform’s secure storage.
• Operations: runs on my own server behind a tunnel; Helmet, a CORS allowlist, request size limits, rate limiting and required-env validation as a baseline. Every response carries a request id and errors follow one JSON contract, so a user-visible failure can be traced without logging bodies or credentials.
