About

Arnage

Features
Read full description

Arnage is a warm, cinephile player for the media library you already own. Follow a series, and every new episode downloads itself in the background โ€” ready to watch even with no signal. Connect it to your home server and open your films and shows in a calm, photographic interface โ€” on your iPhone and your iPad. And if your server carries live channels, Arnage brings them along too โ€” with a full programme guide and a player made for live. โ€” Follow a series, never miss an episode โ€” Follow a show and Arnage downloads each new episode for you, quietly, in the background. Board the plane with the next three already on your iPhone, no Wi-Fi required. โ€” Live TV, with a real programme guide โ€” If your server carries live channels, they are in Arnage too. Browse the guide by channel and by hour, jump to tonight or to another day, see what is on right now, and open any programme for its details before you tune in. While you watch, pause the broadcast and โ€” wherever your server keeps a buffer โ€” step back through what has already aired, then return to live in one tap. (Requires the Pass.) โ€” Made for people who curate their own collection โ€” A quiet, photographic interface that treats your library like the collection it is โ€” continue watching, recently added, and a hero that highlights what's worth your evening. Looking for something in particular? The filters in the Library tab get you there fast, with artwork sized right for every screen. โ€” Playback that respects the file โ€” โ€ข Every file plays directly by default โ€” never re-encoded โ€” with HDR tone-mapped on the spot so it looks right even on an SDR screen. โ€ข On a weak or metered connection, set a quality cap and your server scales the stream down to fit โ€” so you keep watching. โ€ข PGS subtitles and TrueHD audio. โ€ข Your audio and subtitle track choices are remembered for each film and series. โ€” A player built for watching โ€” Swipe across to seek, slide along the edges to set volume and brightness, double-tap to skip โ€” and scrub with live thumbnail previews to land on the exact moment. Pop the video into Picture-in-Picture to keep an eye on it while you get on with something else. โ€” iPhone and iPad, each its own โ€” Designed for each screen rather than stretched between them. โ€” Free to watch, and a Pass for more โ€” Browsing and playing your library is free. The Pass โ€” monthly, yearly, or once for life โ€” adds downloads and followed series, live TV, and connecting more than one server. โ€” Compatibility โ€” Arnage works with Jellyfin and Plex today โ€” point it at the server you already run. More are on the way. โ€” A word on privacy โ€” Arnage is not an advertising surface. We collect two things, both anonymous and both optional: crash reports, so we can fix what breaks, and usage analytics, so we know which features matter. You'll find both switches during onboarding โ€” before you connect to anything โ€” and any time in Settings โ†’ Privacy. Nothing is ever sold, shared with advertisers, or tied to your identity. Your library, your viewing history, and your credentials are never sent to us โ€” and your watch progress lives on your own media server, never on ours. โ€” Status โ€” Arnage is in active development. Expect rough edges, expect care.
