What mobile first trackers need from IMDb list sync tools

A mobile first tracker needs a practical way to save movies and shows, keep a watchlist useful, and find titles again without depending on a desktop. The next question is what should happen to an IMDb list after it has been collected. Some people want a personal record of what they watch, while others want selected titles passed to Radarr for movies or Sonarr for shows. Those jobs overlap, but they are not the same.

A useful comparison starts with the destination. A tracking app can record viewing activity, a list service can help organize titles, and a tool connected to Radarr or Sonarr can pass titles into an existing media workflow. Watcharr takes a public IMDb list and produces one link for Radarr and another for Sonarr. ^[1]

Phone access also matters. Consider whether the main task is saving a title while away from a computer, reviewing a collection, checking recommendations, or maintaining lists that feed a home media server. The available information differs by tool, so a feature that matters for one job should not be assumed to exist in another.

Before choosing, check how a list is updated, whether the tool accepts the source list, and what happens when a title cannot be matched. If the destination is Radarr or Sonarr, confirm that the tool actually supports that handoff rather than simply tracking viewing history.

MDBList for mobile first trackers

MDBList supports combining information from rating services including IMDb, TMDb, Letterboxd, Rotten Tomatoes, Metacritic, MyAnimeList, and RogerEbert through its Stremio integration. ^[3] Its site also features Streaming Charts. ^[2]

The stated features cover building and curating lists and combining rating information. ^[2] ^[3] The available facts also identify a Supporter membership, with sign-up through Memberful and Patreon. ^[2]

For an IMDb to Radarr or Sonarr workflow, check the current list export options and whether the destination can consume the resulting list. The stated features establish list and rating capabilities, but do not by themselves establish a direct IMDb list handoff to both apps.

Trakt for mobile first trackers

Trakt is free on the web, iOS, and Android. ^[4] The stated platforms are the web, iOS, and Android. ^[4]

Trakt states free access on the web, iOS, and Android. ^[6] The stated access is free on the web, iOS, and Android. ^[6]

If the goal is to move IMDb lists into Radarr or Sonarr, check the exact import route and whether it supports the list format already in use. The available facts here do not establish that direct connection, so it should not be assumed from Trakt's mobile availability alone.

Traktarr for mobile first trackers

Traktarr uses Trakt.tv to find shows and movies to add to Sonarr and Radarr, respectively. ^[7] It supports public lists. ^[7]

Its documented role is to use Trakt.tv to find shows and movies for Sonarr and Radarr. ^[7] Its documented input includes public lists. ^[7] The stated source is Trakt.tv, so check whether the current route supports the IMDb list you want to use.

Traktarr requires Python 3.5 or newer. ^[7] Check this stated requirement before choosing Traktarr. ^[7] Its documented use of Trakt.tv is with Sonarr and Radarr. ^[7]

Simkl for mobile first trackers

Simkl tracks TV shows, anime, and movies. ^[5] It also offers personalized AI recommendations. ^[5]

The stated features cover tracking TV shows and movies. ^[5] Simkl tracks TV shows and movies and offers personalized AI recommendations. ^[5] ^[5]

Simkl also provides an API for developers based on watch history. ^[5] If the intended setup involves another app, check whether the current integration supports the required list data and destination. Do not assume that tracking history or recommendations automatically mean a list can be imported into Radarr or Sonarr.

Watcharr for mobile first trackers

Watcharr is made by the team that publishes this site. Watcharr accepts a public IMDb watchlist or list from the desktop site, the phone site, or IMDb's other-language pages. ^[1] You paste the list and get one link for Radarr with the movies and another 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 minutes. ^[1] These are scheduled checks, and the timing should not be read as a guarantee that a title appears immediately.

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

If a show cannot be matched to a TheTVDB id, Watcharr leaves it out and tells you which shows were skipped. ^[1] If you sign in, Watcharr re-reads the list about every 15 minutes and warns you when a list fails three reads in a row. ^[1] When a read fails, the links keep serving the last list that loaded correctly. ^[1]

The 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]

Kometa for mobile first trackers

Kometa provides pre-made modular collections and overlays. ^[9] It can create collections based on networks, studios, genres, actors, and decades. ^[9] It can also customize artwork, titles, and summaries. ^[9]

Those features concern the organization and presentation of a media library. For a mobile first tracker, the useful question is whether the goal is to arrange an existing collection for browsing or to pass an IMDb list into Radarr or Sonarr. The documented Kometa features describe library collections and presentation, so confirm the current list input and automation options before treating it as a direct list sync tool.

Matching the tool to the job

For a public IMDb list that should feed an existing Radarr and Sonarr setup, Watcharr provides separate links for movies and shows. ^[1] Its scheduled checks and list matching behavior are relevant if the list changes over time. ^[1] ^[1]

For mobile access to a tracking service, Trakt offers web, iOS, and Android access. ^[4] Simkl tracks movies, television, and anime and provides personalized recommendations. ^[5] ^[5] These features address tracking and discovery, so check separately whether either service supports the exact IMDb import and media server handoff needed.

For a workflow that uses Trakt lists to add titles to Radarr and Sonarr, Traktarr documents that connection. ^[7] Public list support is also documented. ^[7] The input requirement matters because the available facts do not establish that an IMDb list can be used directly.

For list discovery and rating information, MDBList offers rating-platform information through its Stremio integration and has a Streaming Charts section. ^[3] ^[2] For arranging collections and artwork in a media library, Kometa documents collection and presentation features. ^[9] ^[9]

Choose according to the destination, not just the number of features. Tracking what has been watched, building a list, organizing a library, and importing titles into a media server are separate tasks. A phone-friendly interface is useful only if the rest of the workflow supports the outcome you need.

Questions to ask before you choose

Start with the list source. Check whether the tool accepts a public IMDb watchlist, an IMDb list, a Trakt list, or another input, and whether the supported route matches the list already maintained on a phone.

Next, check the destination. If the goal is to add movies to Radarr or shows to Sonarr, confirm that the tool passes titles to those apps rather than only recording viewing history or arranging a library. Ask how unmatched titles are handled and whether skipped items are reported.

Check the update schedule and what happens when a source list cannot be read. Scheduled updates can take time, so find out how often the tool checks for changes and whether it retains the last successful list when an update fails.

Finally, consider the amount of server maintenance involved, the need for an account, the licence terms, and the phone experience. Check current pricing where applicable, any extra service requirements, and whether the tool can handle the exact list workflow without adding unnecessary steps.
