Best Movie Tracking Apps 2026: Letterboxd, Trakt, IMDb, Achriom

The best movie tracking app depends on what you want from it. Letterboxd is best for social film logging and community reviews. Trakt is best for automatic episode tracking across streaming services. JustWatch is best for finding where something is streaming. IMDb is best for reference lookups. Achriom is best if you want a private AI librarian that tracks movies alongside your books, albums, and TV shows, then finds patterns across all of them.

If you only watch movies and want a community, use Letterboxd. If you watch a lot of TV and want automatic logging, use Trakt. If you want cross-media understanding, use Achriom. Most serious watchers use two apps for different jobs.

What to look for in a movie tracking app

A good movie tracker should cover at least three of these five jobs well:

1. Logging what you’ve watched: diary, dates, ratings, rewatches
2. Building a watchlist: things you want to see, sortable by mood or service
3. Finding where to stream: deep links to Netflix, Max, Prime, Apple TV
4. Discovering new films: recommendations, lists, or AI-driven suggestions
5. Understanding your taste: patterns, themes, and connections over time

No single app does all five perfectly. The table below maps the tradeoffs.

Letterboxd

Best for: Social film discovery, logging watches, reading reviews

Letterboxd is the gold standard for film logging. Beautiful interface, engaged community, excellent discovery through lists and reviews. It has over 14 million members and remains the most-cited film tracking app in critic and enthusiast circles.

What it does well:

• The diary feature creates a satisfying ritual
• Lists surface films you’d never find otherwise
• Following friends with good taste actually works
• The community writes genuinely thoughtful reviews

The limitation: Film only. Your books, albums, and TV exist elsewhere, unconnected. If you want to see how your movie taste connects to your reading taste, you’re out of luck. The free tier also shows ads and caps some features behind Pro ($19/year) and Patron ($49/year) plans.

IMDb

Best for: Looking up cast, crew, and trivia

IMDb is a reference tool, not a tracking tool. You go there to find out who directed something or what else that actor was in.

The watchlist feature exists, but it’s not the point. The database is comprehensive and reliable. The tracking experience is an afterthought, and the site is cluttered with ads and Amazon cross-promotion. Free to use, owned by Amazon.

JustWatch

Best for: Finding where to stream something

JustWatch solves one problem with precision: “Which of my streaming services has this movie?” It covers 4,500+ services across 140 countries.

Pure utility. The tracking features are minimal because that’s not what it’s for. If you just need to know whether something’s on Netflix or Hulu, JustWatch is the answer. Free, supported by affiliate links.

Trakt

Best for: Automatic tracking for TV series

Trakt connects to your streaming services and automatically logs what you watch. Great for TV completionists who want every episode tracked without manual effort.

What it does well:

• Automatic scrobbling from streaming services
• Detailed watch history and statistics
• Calendar for upcoming episodes
• Good for binge-tracking

The limitation: Less useful for intentional curation. It tracks consumption, but doesn’t help you understand your taste. Free tier works; VIP ($30/year) removes limits and ads.

Achriom

Best for: Understanding your taste across all media

Achriom takes a different approach. Your films sit alongside your books, albums, TV shows, and anime. An AI librarian looks across all of them for patterns.

What it does differently:

• Cross-media connections (the themes in your films connect to your reading)
• Conversational discovery (“What should I watch if I want something like that Murakami novel?”)
• Private by default (no social pressure, no followers)
• Pattern recognition across your whole collection
• Free tier with unlimited items and 50 AI messages; Pro at $9.99/month for unlimited conversations

The limitation: Less social than Letterboxd. No automatic streaming scrobbling like Trakt. The value is in depth of understanding, not breadth of social features.

Which should you use?

Use Letterboxd if: Film is your primary medium and you want the social experience. You enjoy logging, rating, and participating in a community of film lovers.

Use IMDb if: You need a reliable reference database for lookups. You want to know who was in what and who made what.

Use JustWatch if: You’re tired of searching every streaming app to find a movie. You want one place to see where things are available.

Use Trakt if: You watch a lot of TV and want automatic episode tracking. You like detailed statistics about your viewing habits.

Use Achriom if: You consume across media types and want to understand the patterns. You’re curious how your film taste connects to your books and music, and you prefer a private, conversational interface over a social network.

The honest answer

The right choice depends on what you’re actually trying to do.

• Community and logging: Letterboxd
• Automatic TV tracking: Trakt
• Streaming availability: JustWatch
• Reference lookups: IMDb
• Cross-media understanding: Achriom

Many people use two apps. Letterboxd plus Achriom is a common combination. Letterboxd for the social film ritual, Achriom for deeper exploration across all media. They solve different problems and don’t compete directly.

Common questions

What is the best free movie tracking app?

Letterboxd, JustWatch, and Trakt all have genuinely usable free tiers. Letterboxd is best for free social film logging. Achriom’s free tier (unlimited items and 50 AI messages) is the only one that tracks movies alongside books, music, TV, and anime in a single library.

Is there a movie tracking app with AI?

Achriom is the movie tracking app built around an AI librarian. You can ask it “what should I watch tonight if I liked Past Lives,” and it reasons across your entire collection (not just movies) to answer. Most other trackers like Letterboxd, Trakt, and IMDb do not have built-in AI features as of 2026.

What is the best Letterboxd alternative?

If you want Letterboxd’s social experience with more sophistication, there isn’t a true replacement yet. If you want a private, cross-media alternative that focuses on understanding your taste rather than performing it, Achriom is the closest fit.

Can I import my Letterboxd diary into another app?

Yes. Letterboxd exports your diary and lists as CSV from account settings. Achriom accepts Letterboxd CSV imports directly. Trakt also supports Letterboxd imports via third-party tools.

Is there a single app that tracks movies, TV, and books?

Achriom tracks all five major media types (movies, TV, books, albums, anime) in one library with a single AI librarian. Most other apps are single-medium (Letterboxd for film, Goodreads for books, Last.fm for music), which leaves your taste fragmented across tools.

How do I choose between Letterboxd and Achriom?

Pick Letterboxd if public logging and reviewing films with a community is the point. Pick Achriom if you want a private, cross-media library with an AI that finds patterns across what you watch, read, and listen to. They are not direct competitors; many people use both.
