Arrk is a native iPhone app for your Radarr and Sonarr servers. Browse your library, add missing titles, choose releases and track downloads without opening a browser. • Connect directly to your servers over local Wi-Fi or a VPN such as Tailscale. No Arrk account and no cloud relay. • Server addresses and API keys stay securely in your iPhone keychain. • Automatic discovery finds Radarr and Sonarr on your network, so you do not need to look up IP addresses or ports. • See upcoming movies and episodes from every server in one calendar, grouped by date, with premieres and finales highlighted. • Browse each library as a fast poster grid or compact list, with search, sorting and filters for available, missing and monitored titles. • See artwork, cast, ratings, seasons and files together on clear, detailed pages. • Add titles using your existing quality profiles and root folders, or search releases manually and compare quality, size and seeders. • Organise your library with Radarr and Sonarr tags: tag titles from their detail page or while adding them, and tidy up unused tags in server settings. • View both queues on one screen, follow progress in real time and get notified when a download finishes. Server health and free disk space are always close at hand. • Search your history of grabs, imports and failures, with the tools you need to deal with anything that gets stuck. • Make it yours with an accent colour, light or dark mode, haptics and animations. Available in English, Italian, Spanish, German and French. Arrk requires a Radarr and/or Sonarr installation that your iPhone can reach over local Wi-Fi or VPN.
