## Projects
- [earbind](https://byaga.dev/projects/earbind/) — An audiobook, as a page instead of a file. Audio, full transcript, real chapters, and a search that jumps to the exact word — no app, no account, nothing to install.
- [elbow](https://byaga.dev/projects/elbow/) — A home-cleaning app for iOS: room-by-room routines, appliance care, stain rescue, and household sharing. Private by design — your data stays in your own iCloud, never on my servers. Live on the App Store.
- [bayley film club](https://byaga.dev/projects/film/) — A season-based film criticism site — each season spotlights one director, handpicked films, full written reviews, and a custom 3-tier rating system (Anticipation · Enjoyment · Retrospect).
- [life in the uk: flashcards](https://byaga.dev/projects/liuk/) — A comprehensive revision tool for the Life in the UK citizenship test — the one I used and passed. Multiple choice questions, monarch family tree, historical timelines, notable Britons, and UK law diagrams. Free on the web and on the App Store for iOS.
