Score: 5.0/10 (Innovation: 4, Technical: 4, Documentation: 7, Utility: 5)

Ballast is a privacy-first, offline-capable Progressive Web App (PWA) for tracking fitness metrics like weight, body measurements, strength PRs, and calisthenics skills. It's interesting because it champions a local-first, no-cloud, no-subscription model as a direct critique of expensive commercial fitness apps, storing all data in the browser's localStorage.

Target audience: frontend devs, fitness enthusiasts, privacy-conscious users
