Best Movie Discovery Apps in 2026: 6 Compared

The best movie discovery app is the one that matches how you decide what to watch. Achriom is the pick if you want your next film to come from your own shelf of films, shows and books, and JustWatch or Reelgood is what you add to see where it streams.

Achriom keeps everything you have watched, read and played on one shelf, free with no item limit, and builds a Home from it. Rows like “Shot by”, “Scored by” and “Because you stayed with” follow the people and sensibilities behind the films you keep, and every title page shows where to watch it. The five other apps here each do one part of the job well, and the sections below say which part.

What to look for in a movie discovery app

A good discovery app covers at least three of these five jobs.

1. Where to watch it. Streaming, free with ads, rent or buy, in your country.
2. Filtering by signal. Genre, year, runtime, score.
3. Other people’s taste. Lists, reviews, critic scores.
4. Your own taste. Suggestions that start from what you have already loved.
5. Context across media. The film that connects to the book or album you are into this month.

No single app covers all five, and the table below shows who covers what.

The six apps compared

Achriom

Best for finding your next film from everything you already love.

Achriom starts with a shelf. Your films sit beside your shows, books, albums, anime, podcasts, games and manga, and you can bring in a history you already have. The import dialog takes a Letterboxd export zip, CSV or username, IMDb ratings or a watchlist, Trakt by username, and Goodreads, StoryGraph and more.

Home is where discovery happens. The rows come from your own shelf, so a film you rated highly leads to more shot by the same cinematographer, scored by the same composer, or directed by the same person. Further down are rows for what is streaming now on the services you pick and what is new for you. Trailers play inside the rows. You can also ask your shelf in plain words, ”80s horror I haven’t watched”, and search by meaning.

Every title page has the trailer, cast, a one-tap rating and a Where to Watch panel for your region. It sorts stream, free with ads, and rent or buy, with the data from JustWatch.

At ten items Achriom writes your Taste Portrait, a name for your taste with the titles behind it. The portrait is free. The deeper readings beneath it are part of Pro, which is $9.99 a month or $99 a year. The free plan has no item limit, and your whole library exports as CSV.

Achriom is private by default. Turn on a public profile when you want one, then follow people and share reviews, lists and your diary. Follower counts stay private.

The limitation is that it does not replace a critic aggregator, so keep Rotten Tomatoes for a quick score. Our guide to the Achriom movie tracker covers the film side in full.

JustWatch

Best for checking what is streaming on your services.

JustWatch describes itself as a streaming guide. It shows where a film or show can be watched, with trending and popular lists, filters, and a guide to upcoming releases. Its watchlist syncs across devices with a free account, and the App Store listing says it notifies you when a title becomes available on one of your services. The Google Play listing mentions a daily timeline of new releases on the services you choose.

The limit is taste. JustWatch tells you what is available, not what fits you. For a feature-by-feature look at it next to its closest rival, read JustWatch vs Reelgood.

Reelgood

Best for a streaming watchlist with alerts and a random pick.

Reelgood is a streaming guide for finding what to watch and where. Its App Store listing says you pick your streaming services, browse curated collections, see IMDb and Reelgood scores, build and share custom lists and use Roulette for a random pick. It notifies you when a new episode arrives or a movie is added to your services, and the app is free to download.

The limit is scope. It is a guide to what is available, not a shelf of everything you have watched, read and played. The two apps are compared head to head in JustWatch vs Reelgood.

Rotten Tomatoes

Best for a quick second opinion.

The Tomatometer is the percentage of professional critic reviews that are positive, and a title with at least 60% positive reviews is Fresh. The Popcornmeter is the same idea for audience ratings, and when a title has verified ratings from people who bought tickets, that score is the default. The site’s Movies at Home section links out to streaming partners.

It answers “is this worth two hours” fast. It does not know what you like, so use it as a check after you have a shortlist.

IMDb

Best for a database of ratings and a Top 250.

IMDb is a subsidiary of Amazon. Registered users submit ratings, and those ratings feed its Top 250 list, with a separate Top 250 for television. You can show your personal ratings on your profile.

It is a reference more than a recommender. Treat the Top 250 as a list of what many people rate highly, then look elsewhere for what fits you.

Letterboxd

Best for lists and reviews from other film fans.

Letterboxd is a social app for movie fans. You log films with a date, rating, review and tags, mark films as liked, watched or on your watchlist, follow other members, and read and comment on their reviews and lists. Discovery comes from the lists and the people you follow. Pro adds stats pages, advanced activity tools, streaming service filters, list cloning and no third-party ads. The App Store listing prices Pro at $18.99 a year and Patron at $48.99 a year.

The limit is that it covers film only. Your books and albums sit somewhere else, and so does anything you want connected across them. If you are thinking of moving, see the best Letterboxd alternatives.

How to check where a movie or show is streaming

Search the title, then pick your country, because streaming rights differ by country. Any of these will answer it.

1. JustWatch. Search the title and it lists the services that carry it. If you want a standing alert, add it to your watchlist and JustWatch notifies you when it reaches one of your services.
2. Reelgood. Pick your subscriptions once, and its watchlist alerts you when a title arrives on one of them.
3. Achriom. Open the title page and read the Where to Watch panel. It splits stream, free with ads, and rent or buy, and it carries a link to more options on JustWatch. The Home row “Streaming now on” does the same for the services you pick.
4. Rotten Tomatoes. Its Movies at Home section links to streaming partners from a title.
5. IMDb. Search the title and look below the poster, where IMDb lists subscribe, rent or buy options for your location.
6. Letterboxd Pro. Adds streaming service filters, powered by JustWatch, according to its App Store listing.

If you keep several services, how to track movies across streaming services walks through setting this up once.

Which should you use?

Pick Achriom if you want the next film to come from what you already love, and you also read, play or listen. Your shelf stays in one place, and you can ask it for something.

Pick JustWatch if you want the cleanest answer to where something is streaming right now.

Pick Reelgood if you want a streaming watchlist that alerts you, and you like the random pick for nights you can’t decide. See JustWatch vs Reelgood to choose between the two.

Pick Rotten Tomatoes for a quick check after you have a shortlist.

Pick IMDb if you want to browse a database of user ratings and the Top 250.

Pick Letterboxd if you trust other film fans’ lists and reviews, and mostly care about film.

A workable stack

One app can hold your taste, and another can answer where to watch. A pairing that works is Achriom for the shelf and what to watch next, JustWatch or Reelgood for a standing streaming alert, and Rotten Tomatoes for a score before you press play.

Common questions

What is the best movie discovery app in 2026?

It depends on how you decide what to watch. Achriom is built for picking your next film from your whole shelf of films, shows and books. JustWatch and Reelgood are built for checking where a title streams, and Rotten Tomatoes and Letterboxd are built for reading what critics and other viewers think.

How can I check if a show is available to stream?

Search the title in a streaming guide and pick your country. JustWatch and Reelgood both list the services that carry a film or show, Achriom shows stream, free with ads, rent and buy options on every title page, and Rotten Tomatoes links out to streaming partners from its Movies at Home section.

JustWatch or Reelgood, which should I use?

Both answer where a film or show is streaming. JustWatch alerts you when a watchlist title reaches one of your services, and Reelgood adds a random-pick Roulette, curated collections and custom lists. Pick the one whose app you like opening, and keep your actual viewing history somewhere else.

What is the difference between a movie tracking app and a movie discovery app?

A tracking app logs what you have already watched. A discovery app helps you find what to watch next. Letterboxd logs films with a date, rating and review, JustWatch and Reelgood are streaming guides, and Achriom keeps your shelf and builds its Home from it.

Is there a movie discovery app that works from my own taste?

Achriom builds its Home rows from your shelf, for example films shot by a cinematographer you rate highly or scored by a composer you keep coming back to. At ten items it also writes your Taste Portrait, and you can ask your shelf for things like 80s horror you haven’t watched.

Can I bring my Letterboxd or IMDb history into Achriom?

Yes. The import dialog takes a Letterboxd export zip, CSV or username, and IMDb ratings or a watchlist. Trakt, Goodreads and more are there too, and free plans have no item limit.
