How multi-service watchlist syncers can keep each list in step and stop titles being missed when services drift apart.

Multi-service watchlist syncers can avoid missing titles by keeping one source list, knowing how each service refreshes it, checking that every title was added, and recording the ones a service skips so they can be added another way.

| Option | How titles stay in step | Cost details |
|---|---|---|
| Watcharr | You paste one public IMDb list and get one link for Radarr with the movies and one for Sonarr with the shows. [^1] Radarr checks its link every 15 minutes and Sonarr every 5. [^1] | not published |
| Checking each service's list page by hand | You open each service's list page and compare it with your watchlist, then add any title that is missing. | not published |
| A shared note per service | You keep one note per service list and update it by hand when a title is added or left out. | not published |

## What you need before you start

When one watchlist is spread across several services, a title can be missed when one service updates its list later than another. To close that gap, start by writing down which services hold your watchlist and how each one refreshes it. Name the service that adds titles to your library, and name the list that service reads from. Choose one source list and treat it as the current version, because services that copy from it drift apart when they check at different times. Decide how often each service checks the list and pick a way to see when a check fails, so a missed title is caught early. Have the details of each service ready: the account that owns the list, whether the list is public, and what a title must have before a service will add it. If any title is skipped, keep a record of which ones were skipped and why, so you can add them another way. Getting these things ready before a title slips through is what this page helps you do.

## Step by step

1. Pick one source list and make it public so every service that reads it can see it.

2. Write down which service reads the list first and which reads it last, so you know the order titles move in.

3. Set each service to check the list on a schedule you know, and note how long one check takes.

4. After each service runs, check whether every title on the source list was added, and look at the ones that were not.

5. Tell each service what a title must have before it is added, such as a matching id, so a title that cannot match is skipped early instead of failing later.

6. Keep a list of titles that were skipped or left out, and add them by hand when a service cannot.

7. On a set day each month, review the whole flow and fix any list that stopped loading.

8. Tell the people who use the watchlist what to do when a title is missing, so the problem reaches you instead of going unnoticed.

## Tools that can do it

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. [^1] Radarr checks its link every 15 minutes and Sonarr checks its link every 5 minutes. [^1] A bookmark you click inside Radarr or Sonarr adds the list for you, using that app's own access key, which is never sent anywhere else. [^1]

Watcharr accepts any public IMDb watchlist or list from the desktop site, the phone site or IMDb pages in other languages. [^1] The same IMDb list always gives the same Radarr and Sonarr 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, Watcharr 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 hosted version needs nothing to install and no account. [^1] Watcharr runs as one Cloudflare app with a Cloudflare database, plus a GitHub job that reads IMDb. [^1] Its code can be read and run for noncommercial use, such as a household setup, and older versions are under a more permissive licence. [^1] Commercial use is not licensed, and no commercial licence is for sale. [^1]

You can paste an IMDb list, copy the resulting links, and browse your titles from any screen in the web app. [^1] The page shows the list's cover images in a row, and each one opens the title's plot, genres, rating and trailer. [^1]

Before choosing a tool, check how it refreshes a source list, how it reports a check that fails, whether it skips titles it cannot match, and whether it keeps serving the last list that loaded correctly.

## Common mistakes to avoid

Avoid assuming every service refreshes the same list at the same time. Schedules can be delayed, so check what a service is running rather than trusting that a title appeared the moment it was added.

Avoid leaving a skipped title unreported. A service may leave out a title it cannot match, and if nobody tracks that, the title is simply missing. Record skipped titles and add them another way.

Avoid treating a stale list as current. If a read of a list fails, an older copy can keep being served, so a new title on the source list will not appear until the list loads again.

Avoid skipping the privacy check. Look at what information a tool asks for and what access it uses before sharing a list with other people.

## Frequently asked questions

### Why do titles get missed when services drift apart?

When one watchlist is spread across several services, each service updates its list on its own schedule, so one service can show a title before another does. If a title is added to the source list but a service last checked before that, the service will not add it until it checks again. A scheduled run can also be delayed, and a read of a list can fail. Checking after each service runs whether every title was added, and recording titles that were skipped, helps catch the ones that would otherwise be missed.

### Can Watcharr stop a title being missed?

Watcharr gives you a link for Radarr with the movies and one for Sonarr with the shows from a pasted IMDb list. [^1] Radarr checks its link every 15 minutes and Sonarr every 5. [^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, Watcharr also warns you when a list fails three reads in a row. [^1]

### Does Watcharr need anything installed?

The hosted version needs nothing to install and no account. [^1] You paste one public IMDb list and get one link for Radarr with the movies and one for Sonarr with the shows. [^1] A bookmark you click inside Radarr or Sonarr adds the list for you. [^1] Watcharr runs as one Cloudflare app with a Cloudflare database, plus a GitHub job that reads IMDb. [^1]

### What happens when a list read fails with Watcharr?

If a read of the list fails, the links keep serving the last list that loaded correctly. [^1] If you sign in, Watcharr re-reads your list about every 15 minutes and warns you when a list fails three reads in a row. [^1] That means a new title on the source list will not appear until the list loads again, so a warning is the sign to check why the read failed.

### What should be checked before choosing a tool to avoid missed titles?

Check how a tool refreshes a source list, how it reports a check that fails, whether it skips titles it cannot match, and whether it keeps serving the last list that loaded correctly. Check what the tool is licensed for, since commercial use of Watcharr is not licensed and no commercial licence is for sale. [^1] Compare those details with the way the services are managed before choosing a method.

Its code is available to read under the PolyForm Noncommercial 1.0.0 licence; older versions remain under MIT. [^1] - [Visit Watcharr](/go/start-watcharr)
