What you need before you start

Anime list keepers usually track their ratings in more than one place, such as a personal list, a public site and a library app. Before you start, pick the one place where your master copy will live, and write down what each score means to you so the scale stays the same.

Gather the titles you already rate and check whether they appear on a public IMDb list. Watcharr, the tool covered later on this page, accepts any public IMDb list, including lists from the desktop site, the phone site and IMDb's other-language pages. ^[1] Have your movie app and your show app ready, and confirm you can open their settings.

Decide how often the lists should update and who in your household needs access. Write these answers down before you change anything.

Step by step

Choose one place to keep your master copy of ratings, and note what each score means.
Put the titles you rate into one public IMDb list, so every rating starts from the same source.
Choose a tool that reads that list and passes it on to your movie app and your show app.
Add the links from that tool to each app, following the tool's own instructions.
Check a handful of titles in each app against your master copy, and confirm the scores match.
Once a week, look for titles the tool skipped or failed to read, and fix them in the list.
Update the master copy first whenever a rating changes, so the apps always follow one source.

Keep a short note of any step that caused trouble, so the next setup goes faster. Changes are easier to trace when only one place is edited.

Tools that can do it

Watcharr is made by the team that publishes this site, VLClean. 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 own key without sending it 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 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] If a read fails, the links keep serving the last list that loaded correctly. ^[1] It leaves out shows it can't match, and tells you which ones it skipped. ^[1] The page shows the list's covers in a row, and each one opens its plot, genres, rating, backdrop and trailer. ^[1]

The table compares the options named here. Radarr and Sonarr are the two apps Watcharr's links feed. ^[1] No other tool's facts are given on this page, so for any other option, check how it reads an IMDb list, how often it refreshes, and whether it reports titles it skipped.

Common mistakes to avoid

Avoid setting the IMDb list to private, since Watcharr accepts public lists. ^[1]

Avoid reading a missing show as an error. Watcharr leaves out shows it cannot match, and tells you which ones it skipped. ^[1]

Avoid keeping ratings in several places at once. Update the master copy first, so the apps follow one source.

Avoid ignoring the list after setup. A list that fails to read keeps serving its last good copy, so check the titles each week. ^[1]

Avoid assuming the tool can be used for business work. Commercial use is not licensed, so check the terms first. ^[1]

Frequently asked questions

How can anime list keepers keep ratings in one place?

Start with one master copy of your ratings, then put the titles you rate onto one public IMDb list so every app reads from the same source. Choose a tool that passes that list to your movie and show apps, and check a few titles against your master copy each week to make sure the scores match.

Does Watcharr give one link for movies and one for shows?

Yes. 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] The same list always gives the same two links. ^[1]

Does Watcharr cost money to use?

The hosted version needs nothing to install and no account. ^[1] No price is published for Watcharr, so check the product's own pricing before you decide. Commercial use is not licensed, and no commercial licence is for sale. ^[1] The code can be read under the PolyForm Noncommercial 1.0.0 licence, and older versions remain under MIT. ^[1]

Can Watcharr show ratings for each title?

The page shows the list's covers in a row, and each cover opens its plot, genres, rating, backdrop and trailer. ^[1] Nothing here says it stores your own scores, so check that before you rely on it as your master copy. Use it to look up titles, and keep your scores in your own master copy.

What happens if Watcharr cannot read the list one time?

If a read of the list fails, the links keep serving the last list that loaded correctly. ^[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] Check the titles in your apps after a warning, and fix any list problem before the next read.
