If two people share an IMDb watchlist and use Radarr or Sonarr, Watcharr turns a public IMDb list into separate links for movies and shows, which those apps check on their own schedules. ^[1] MDBList creates dynamic, automatically updated movie and show lists, while Trakt is free to use on the web, iOS, and Android. ^[2] ^[3] The right choice depends on whether the goal is to share a viewing list, keep track of watched titles, organize a media library, or send selected titles to existing media apps.

What couples watchlist sharers need from IMDb list sync tools

Sharing a watchlist is useful when two people want to keep track of movies and shows they may watch together. The practical question is what should happen after a title gets added. A shared list might simply help both people remember what to watch, or it might feed titles into Radarr and Sonarr so a home media library can pick them up. Those are different jobs, so a tool that organizes viewing history is not automatically a tool that sends titles to media apps.

A couple should decide whether one shared IMDb list is enough or whether separate lists need to be combined. It also helps to consider whether the list should update automatically, whether titles need to be separated into movies and shows, and whether missed matches should be visible. If both people contribute titles, a consistent list can make it easier to keep selections in one place.

Setup matters too. Some tools offer a hosted website, while others involve running software or managing a media library. A person maintaining a home server may prefer fewer installation steps, while someone who wants more control over collections may accept more configuration. The choice should follow the intended job, not the number of features listed on a product page.

MDBList for couples watchlist sharers

MDBList creates dynamic movie and show lists that update automatically and can be tailored to user preferences. ^[2] Its site also offers a Supporter membership with sign-up through Memberful and Patreon. ^[4] This makes it worth considering when the shared activity centers on creating and maintaining lists rather than only tracking what has already been watched.

For a couple, the main question is how the desired list should be built and whether its output can feed the existing media setup. Automatic list updates address list maintenance, but the available facts do not establish that every list can be sent directly to Radarr or Sonarr. Check the current sharing options, list sources, and any requirements for using the exact workflow needed.

Trakt for couples watchlist sharers

Trakt is free to use on the web, iOS, and Android. ^[3] That gives couples a way to consider a web or mobile option when deciding where to keep track of viewing activity.

The key distinction is between tracking what each person watches and passing a shared IMDb list into a home media library. The available facts establish Trakt's access options and price status, but do not establish the details of a direct IMDb-to-Radarr or IMDb-to-Sonarr workflow. Check whether the current list and account features support the intended sharing arrangement before choosing it for library automation.

Traktarr for couples watchlist sharers

Traktarr uses Trakt.tv to find shows and movies to add to Sonarr and Radarr, respectively. ^[6] It supports public lists and can add a single movie to Radarr. ^[6] ^[6]

This option is relevant when the aim is to move titles from supported Trakt lists into existing media apps. Couples who start with IMDb should check how their particular list can be represented in the workflow, because the available facts do not establish direct IMDb list input. It is also worth checking the current setup requirements and how list selections are handled before relying on it for a shared household library.

Simkl for couples watchlist sharers

Simkl tracks TV shows, anime, and movies. ^[7] It offers Free, Pro, and VIP membership options. ^[7] Its listed features include calendar support with more than 20 calendars and iCAL sync. ^[7]

For a couple, tracking and scheduling may matter as much as building a list of titles to add to a server. Simkl is worth comparing when the goal includes keeping track of viewing and using a calendar. The available facts do not establish that it turns an IMDb watchlist into Radarr and Sonarr import links. Check the current list import, sharing, and media-server options if automatic library additions are part of the plan.

Listrr for couples watchlist sharers

Listrr creates personalized lists for shows and movies with filters, and every list it creates updates automatically. ^[8] ^[8] Donors can create lists with an unlimited amount of items. ^[8]

This approach is worth considering when both people want a list shaped by specific preferences rather than a simple record of titles they have saved. Automatic updates can reduce the need to maintain each list manually. Couples should check which filters and sharing options are available for their intended use, along with whether the resulting list can be used directly by their existing media apps. The available facts do not confirm a direct IMDb-to-Radarr or IMDb-to-Sonarr workflow.

Watcharr for couples watchlist sharers

Watcharr is made by the team that publishes this site. Watcharr accepts a public IMDb watchlist or list and gives it two links, one for Radarr with movies and one for Sonarr with shows. ^[1] Each link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5 minutes. ^[1] These are check intervals, not a promise that every change will appear immediately.

The hosted version needs nothing to install and no account. ^[1] You paste, copy, and browse from any screen in the web app, although the one-click bookmark appears on bigger screens. ^[1] A bookmark clicked inside Radarr or Sonarr adds the list using that app's API key without sending the key anywhere else. ^[1]

The links are built from the IMDb list's ID, so the same list always gives the same two links. ^[1] If a show cannot be matched to a TheTVDB ID through the supported lookup process, Watcharr skips it and tells you which shows were skipped. ^[1] Signed-in users can combine several IMDb lists into one Radarr link and one Sonarr link for the household, with duplicate titles added only once. ^[1] If a list read fails, the links keep serving the last list that loaded correctly. ^[1]

Watcharr is a hosted service, so the work of reading IMDb lists and checking them runs in the background instead of on equipment in the home. ^[1] Its code is available to read under the PolyForm Noncommercial 1.0.0 licence, while older versions remain under MIT. ^[1] Commercial use is not licensed, and no commercial licence is for sale. ^[1]

Matching the tool to the job

For a shared public IMDb list that should feed an existing Radarr and Sonarr setup, Watcharr turns one list into separate movie and show links. ^[1] If several lists need to become one household feed, signed-in Watcharr users can combine them, and titles appearing on more than one list are included only once. ^[1]

For automatically updated movie and show lists tailored to preferences, MDBList provides dynamic lists. ^[2] For lists shaped by filters, Listrr creates personalized movie and show lists and updates them automatically. ^[8] ^[8] These list-making features are distinct from a confirmed direct IMDb import into Radarr or Sonarr, which should be checked before choosing either option for that job.

For tracking TV shows, anime, and movies, Simkl offers viewing tracking and calendar support. ^[7] ^[7] Trakt is free on the web and mobile devices. ^[5] Couples comparing these services should check how shared lists, separate accounts, and viewing history work for their circumstances.

For adding titles found through Trakt.tv to existing media apps, Traktarr connects Trakt.tv with Sonarr and Radarr. ^[6] For a couple whose priority is a shared IMDb source rather than viewing history or list discovery, Watcharr's direct public IMDb list workflow is the more relevant feature to compare. ^[1]

Questions to ask before you choose

Start by deciding whether the shared list is mainly a record of titles to watch or a source that should add titles to a media server. Check whether the tool accepts the list source already in use, whether it separates movies and shows, and whether it can combine multiple lists when both people maintain their own selections.

Consider how often changes are picked up and what happens if a list cannot be read or a title cannot be matched. If Radarr or Sonarr is involved, confirm how the list reaches those apps and whether any extra setup is needed. A service that tracks viewing activity may address a different need from one that supplies import links.

Finally, check account requirements, installation work, list limits, and licence terms. Watcharr's hosted version needs no installation or account, but its current code licence does not permit commercial use. ^[1] ^[1] The available facts do not establish every option's sharing rules or exact costs, so those details should be verified for the intended setup.

Frequently asked questions

Can Watcharr sync a shared IMDb watchlist with Radarr and Sonarr?

Watcharr accepts a public IMDb watchlist or list and provides one link for Radarr with movies and another for Sonarr with shows. ^[1] Radarr checks its link every 15 minutes and Sonarr checks its link every 5 minutes. ^[1] These are scheduled check intervals, so a change may take longer to appear.

Can Watcharr combine two IMDb watchlists for a household?

Signed-in Watcharr users can combine several IMDb lists into one Radarr link and one Sonarr link for the household. ^[1] A title that appears on multiple lists is included only once. This can help when each person keeps a separate public list but the household wants one feed for movies and another for shows.

Does Watcharr require an account or installation?

The hosted version of Watcharr needs no installation and no account. ^[1] You can paste, copy, and browse from any screen in the web app, although the one-click bookmark appears on bigger screens. ^[1] Signed-in features are available for users who want to combine several lists or use automatic list rereading.

How does Watcharr handle IMDb shows it cannot match?

Watcharr looks up TheTVDB IDs through TVMaze and TMDB, skips shows it cannot match, and tells you which titles were skipped. ^[1] That means the Sonarr link may not contain every show from the IMDb list. Check the reported skipped titles if a particular show does not appear in the feed.

Is Watcharr licensed for commercial use?

Watcharr's code is available under the PolyForm Noncommercial 1.0.0 licence, while older versions remain under MIT. ^[1] Commercial use is not licensed, and no commercial licence is for sale. ^[1] Anyone considering Watcharr for a business or another commercial purpose should review the applicable licence terms before using it.

Its code is available to read under the PolyForm Noncommercial 1.0.0 licence; older versions remain under MIT. ^[1]
