## What household watch trackers need from IMDb list sync tools

Household watch trackers are the people who keep one shared list of movies and shows the whole home wants to watch. The list usually lives on IMDb, because everyone can add to it from a phone or a laptop. The real job of a sync tool is to turn that living list into titles that the home's Radarr and Sonarr pick up, without someone copying each title by hand. The list changes often, because one person adds a sequel and another removes a film they already saw. Households also want the same list to work for everyone, so a title added once is not added twice. A tool that re-reads the list on its own keeps up as the list changes. People also want to know what happens when a read fails, and whether the tool keeps serving the last list that loaded correctly. Matching a tool depends on where the list is kept, how often it is re-read, how titles are matched to Radarr or Sonarr, and what the tool needs to run.

## Watcharr for household watch trackers

Watcharr is made by the team that publishes this site. You paste one public IMDb list and get one link for Radarr with the movies and one for Sonarr with the shows. [^7] Each link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5. [^7] A bookmark you click inside Radarr or Sonarr adds the list for you, using that app's API key without sending it anywhere else. [^7] It accepts any public IMDb watchlist or list from the desktop site, the phone site, or IMDb's other-language pages. [^7] The links are built from the IMDb list's id, so the same list always gives the same two links. [^7] It looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it can't match, and tells you which ones it skipped. [^7] The page shows the list's covers in a row, each opening TMDB's plot, genres, rating, backdrop, and trailer. [^7] If you sign in, it re-reads your list about every 15 minutes and warns you when a list fails three reads in a row. [^7] Signed-in users can combine several IMDb lists into one Radarr link and one Sonarr link for the whole household, and a title that is on two lists is added only once. [^7] If a read of the list fails, the links keep serving the last list that loaded correctly. [^7] Its code is available to read under the PolyForm Noncommercial 1.0.0 licence, and older versions remain under MIT. [^7] You paste, copy, and browse from any screen in the web app, and the one-click sticker shows on bigger screens. [^7] The hosted version needs nothing to install and no account. [^7] Commercial use is not licensed, and no commercial licence is for sale. [^7]

## Matching the tool to the job

Watcharr accepts any public IMDb watchlist or list from the desktop site, the phone site, or IMDb's other-language pages. [^7] For turning one list into Radarr and Sonarr entries, Watcharr gives one link for Radarr with the movies and one for Sonarr with the shows. [^7] For households that keep several lists, signed-in Watcharr users combine them into one Radarr link and one Sonarr link, and a title on two lists is added only once. [^7] For a list that follows Trakt, MDBList syncs a watchlist, ratings, and progress directly with Trakt without leaving its interface. [^1] For adding titles to Sonarr and Radarr from Trakt lists, Traktarr uses Trakt.tv to find shows and movies to add to Sonarr and Radarr. [^4] For building a filtered, personalized list, listrr.pro creates personalized lists for shows and movies with a large number of filters. [^6] For tracking across TV shows, anime, and movies, Simkl tracks those and offers Free, Pro, and VIP memberships. [^5] [^5] For knowing what could not be added, Watcharr leaves out shows it can't match and tells you which ones it skipped. [^7]

## Questions to ask before you choose

Before choosing a list sync tool, consider where the household keeps its list and how often it changes. Ask whether the tool reads public lists or requires a sign-in, and where the list has to live. Check how often each tool re-reads the list and what happens when a read fails, since scheduled runs can be delayed or a list can be unavailable. Ask how titles are matched to Radarr or Sonarr, because shows without a TheTVDB id may be skipped. Check whether several lists can feed one set of links and whether a title on two lists is added once. Ask what the tool costs and whether fees cover commercial use. Check what each tool actually integrates with, since tools vary in which services they read from.
