Shared family list managers can sync a household watchlist by choosing one public list everyone adds titles to, deciding who approves entries, and using a tool that turns that list into regular watch checks.

What you need before you start

Settle on the one shared list that the whole household adds titles to, and name who can add and who approves before a title is treated as watchable. A single list keeps titles from spreading across several places, so the sync stays clean. A shared household watchlist only works when every member adds to the same place.

Choose a public list that a sync tool can read. A public list is one that can be viewed without signing in. Every family member who adds titles should know the list is public before anything is shared, since the tool needs to see it without a login.

Decide whether the household tracks movies, shows, or both, because some tools handle movies and shows in separate places. If shows are included, check whether the tool skips shows whose names it cannot match.

Decide how often the list should be checked and who is told when a title is added. These choices shape which tool fits the household's routine, so settle them before picking a tool.

Step by step

Agree on the one shared list that every member of the household uses to add titles. Name it clearly so nobody starts a second list, because a shared watchlist only stays in sync if everyone adds to the same place.

Decide who can add titles freely and who reviews a title before it counts as watchable. Write those roles down and tell everyone, so nobody is surprised when a title is held back.

Make the list public so a sync tool can read it, and confirm the tool you plan to use supports the list type you picked. A public list is one that can be viewed without signing in.

Write a short note for the household that names the list, who can add titles, and how a member will know a title was treated as watchable. Keep the note simple.

Connect the list to the tool that reads it, and set the tool to check the list on its own schedule. Tell the household how often it is checked, so they know when a title they add will be picked up.

Review the list once a week. Remove titles nobody wants, settle duplicates, and deal with any title the tool skipped.

Ask a few family members after the first week what confused them, and adjust the note and the steps so the process stays easy to follow.

Tools that can do it

Watcharr is made by the team that publishes this site. It turns one shared IMDb list into two links, one for movies and one for shows. ^[1]

You paste one public IMDb list and get one link for Radarr with the movies and one for Sonarr with the shows. ^[1] Each link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5. ^[1] A bookmark you click inside Radarr or Sonarr adds the list for you, using that app's API key without sending it anywhere else. ^[1]

It accepts any public IMDb watchlist or list from the desktop site, the phone site or IMDb's other-language pages. ^[1] The links are built from the IMDb list's id, so the same list always gives the same two links. ^[1] It looks up TheTVDB ids through TVMaze and TMDB, leaves out shows it can't match, and tells you which ones it skipped. ^[1]

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. ^[1] 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. ^[1] If a read of the list fails, the links keep serving the last list that loaded correctly. ^[1]

The page shows the list's covers in a row, each opening TMDB's plot, genres, rating, backdrop and trailer. ^[1] The hosted version needs nothing to install and no account. ^[1] You paste, copy and browse from any screen in the web app, and the one-click sticker shows on bigger screens. ^[1] Commercial use is not licensed, and no commercial licence is for sale. ^[1]

Common mistakes to avoid

A shared household list fails when members add titles in several places. Keep one list, tell everyone to use only it, and name one person who keeps an eye on it.

Avoid choosing a tool without checking how it reads the list you picked. Confirm it reads a public list and handles movies and shows in the way the household tracks them.

Avoid forgetting to review the list after setup. A shared list becomes cluttered if old or unwanted titles are left without attention, so set a regular day to look through it.

Avoid assuming every show can be added. Check whether a tool skips shows whose names it cannot match, what it reports as skipped, and what to do with those titles.

Avoid sharing list access before checking what the tool can see. Review what a tool reads before the household relies on it, and keep the note for members up to date.
