Best IMDb list sync tools for book and film trackers in 2026

Q: How does Watcharr handle shows it cannot match?

Watcharr looks up TheTVDB ids through TVMaze and TMDB. Shows it cannot match are left out, and Watcharr tells you which ones it skipped. This gives a tracker a stated way to identify unmatched shows instead of treating every item in the IMDb list as a successful match.

What book and film trackers need from IMDb list sync tools

A book and film tracker may need to turn an IMDb list into something that can be followed, updated, or used elsewhere. The useful distinction is what happens after a list is created. Some tools focus on building and updating lists, some track media consumption, and some connect lists with media automation tools.

A tracker also needs a clear way to handle titles that do not match another service. Update timing matters when a list changes, but scheduled checks should be understood as recurring checks rather than instant changes. Access to a list matters too, especially when a tracker is meant to work from a public IMDb list.

The options below cover different jobs. MDBList focuses on dynamic movie and show lists, Trakt is free on web, iOS and Android, Traktarr uses Trakt.tv to find titles for Radarr and Sonarr, and Simkl offers membership options and catalog features. ^[1] ^[4] ^[5] ^[6] Watcharr takes a more direct route from one public IMDb list to Radarr and Sonarr. ^[11]

Watcharr for book and film trackers

Watcharr is made by the team that publishes this site. Watcharr takes one public IMDb list and gives you one link for Radarr with the movies and one for Sonarr with the shows. ^[11] Each link acts like a small Radarr or Sonarr server, so Radarr checks it every 15 minutes and Sonarr every 5. ^[11] Watcharr accepts any public IMDb watchlist or list from the desktop site, the phone site, or IMDb's other-language pages. ^[11] The links are built from the IMDb list's id, so the same list always gives the same two links. ^[11]

Questions to ask before you choose

Check whether the tool starts from the list source that matters to the tracker and whether it produces the kind of output needed afterward. For an IMDb list going to Radarr and Sonarr, check whether movies and shows are separated and how unmatched shows are handled. Watcharr separates one public IMDb list into a Radarr link and a Sonarr link. ^[11]

Check how often changes are picked up and what happens after a failed read. Watcharr re-reads a signed-in list about every 15 minutes and warns after three failed reads in a row. ^[11] If a read fails, its links keep serving the last list that loaded correctly. ^[11]

Also check whether installation, account requirements, list privacy, commercial use, and any service connections match the intended setup. Watcharr's hosted version needs nothing to install and no account. ^[11] Commercial use is not licensed, and no commercial licence is for sale. ^[11]
