WatchBox

A native Android anime client built with Kotlin and Jetpack Compose. Content comes entirely from user-installed Aniyomi-compatible extensions — the app ships no sources, no extension repository, and hosts no media of its own.

The interface is a deliberate port of NuvioMobile's design system — same tokens, typography, spacing, poster metrics, floating pill navigation and player chrome.

Features Home — hero pager with auto-advance and parallax, Continue Watching, My List, and one rail per installed source Browse — a grid of installed sources led by their extension icons, each opening paged Popular/Latest grids with per-source search and the source's own filters Extensions — multiple repositories, each independently switchable; search and filter by language, adult content and repository; per-extension settings for extensions that expose them; load failures surfaced rather than hidden Detail — parallax hero with a multi-stop scrim, collapsing floating header, expanding action row, and the episode list Player — Media3/ExoPlayer with HLS + MP4, quality/subtitle/speed pickers, episode switcher, aspect-ratio cycling, tap and drag gestures, brightness and volume swipes, and a lock mode Casting — Chromecast and DLNA in one device list, with a local header-injecting proxy for streams whose CDN requires a Referer, plus a hand-off to Web Video Caster for receivers this app does not speak Subtitles — size, background style (none, outline, drop shadow, box, full-width band), outline/shadow width, colour and opacity, adjustable from Settings or from inside the player Search — debounced search across every installed source at once, grouped per source, or narrowed to a single source Library — My List, in-progress, and full history Settings — seven accent themes, AMOLED black, auto-play-next, repository management, subtitle appearance, and an 18+ toggle
