What imdb watchlist users need from IMDb list sync tools

People keep an IMDb list for many reasons, from a personal watchlist to a shared household list. The main job of a sync tool is to move the titles on that list into the apps that fetch the movies and shows, usually Radarr for movies and Sonarr for shows. An IMDb list can mix movies and shows, so a tool needs to tell them apart and route each title to the right app. A list also changes over time as people add and remove titles, so the tool should re-read it and keep what it hands over current. Some titles on a list cannot be matched to an id that Radarr or Sonarr understands, and a useful tool tells the owner which ones it skipped. Owners often want to share one list for the whole household without a title being added twice. Watcharr keeps the list output current and tells you which titles it could not match ^[9] ^[9] ^[9]. The choice comes down to how the list reaches Radarr and Sonarr, how often it refreshes, and what the tool reports when a read of the list fails.

Questions to ask before you choose

Before choosing an IMDb list sync tool, decide where the watchlist lives, since some tools read IMDb lists while others read Trakt or hold their own catalog. Check how often the tool refreshes the output and what it does if the list cannot be read. Check whether the tool separates movies from shows and routes each to the right app. Ask what the tool reports about titles it could not match, and how long the linked output stays valid. Check whether the whole household can share one list without a title being added twice. Also check what the tool needs to run and what account or membership it requires.
