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.

Verdict
The clearest difference is update cadence: Arrk at every 5 days against GDI Inspect's every 5 months. GDI Inspect's advantage is device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
