Moviebase vs Simkl (2026)
Updated Sep 17, 2026
Last checked 2026-09-17, live re-verified against both sites via the built-in browser pane. Moviebase ships weekly — re-verify specifics before relying on the feature list below.
Moviebase and Simkl both sit past Trakt and Letterboxd on the "how much do I want this app to do for me automatically" spectrum, but they solve it from opposite directions — Moviebase is an app you browse and filter in, Simkl is a background process that happens to have a good website.
What they have in common
•
Both track movies and TV, both list Trakt sync/import as a core feature, and both are aimed at people who've outgrown a basic watchlist app.
•
Both have a usable free tier: Moviebase's is unlimited tracking (ad-supported); Simkl's free tier ships 15 default watchlists (5 status buckets × TV/Anime/Movies) plus lifetime all-time stats.
•
Both import from each other directly — Moviebase lists "Simkl: Import your Simkl backup" among its supported sources, and Simkl accepts Letterboxd, MAL, Anilist, IMDb, Netflix, Kitsu, BetaSeries and CSV imports from its own side.
•
Neither has a household or shared-decision concept. Simkl's "watch with friends" feature compares two people's lists after the fact; Moviebase has follows and an activity feed. Neither is a joint watchlist or a pick made for the room.
Where they differ
What kind of app it is
Moviebase is discovery-first: genre/rating/runtime/provider filters, studio and keyword search, multi-source ratings (TMDB, IMDb, Rotten Tomatoes), home-screen widgets, and a social layer with profiles, follows, comments and an inbox. Simkl is automation-first: its headline is scrobbling from Plex, Kodi, Netflix, Crunchyroll and other services so a watch gets logged without the user touching anything.
Content scope
Moviebase covers movies and TV, with ratings drawn from TMDB, IMDb and Rotten Tomatoes. Simkl adds a third category Moviebase doesn't really compete in — anime (14,892 titles as of this check), plus two-way MyAnimeList sync on paid tiers, on top of its 140,514 TV shows and 1,187,520 movies.
Platform
Moviebase is phone-only — native iOS and Android apps, with moviebase.app serving as marketing and share pages only, no way to use the tracker in a browser. Simkl is a full website plus apps for iOS, Android, Windows, and multiple Chrome extensions — the automation story specifically depends on being reachable from wherever the watching happens (a media server, a browser extension, a phone), so it can't be phone-only by design.
Pricing and free-tier limits
•
Moviebase Premium: price still undisclosed — not published on the site as of this check, revealed only at checkout. The free tier itself is ad-supported but otherwise unlimited — no cap on tracked movies or shows.
•
Simkl: two paid tiers, both transparently priced. PRO is $2.91/mo billed annually ($34.99/yr); VIP is $5.83/mo billed twice a year ($69.98/yr); a Lifetime VIP option is $249 one-time. Smaller niche tiers also exist: $2.99/mo for students/teachers, $1/mo "Supporter." The free tier's own limits: 30 custom lists capped at 2,000 items each, 60,000 items total across all lists — generous, but not unlimited the way Moviebase's tracking is.
•
A genuinely surprising asymmetry: Simkl paywalls importing from Trakt or TV Time, or restoring a JSON backup, behind PRO/VIP — while Moviebase's own Trakt sync (two-way) and its list of import sources, including a Simkl backup, are free.
Recommendations
Simkl's site markets a personalized recommendation engine as a PRO/VIP perk, positioned to "find your next favorite Movie, TV show, or Anime in a snap" based on watch history. Moviebase's equivalent — "Personalized Recommendations" based on watch history and ratings — is listed as a free-tier feature, not gated behind Premium.
Which one, if you have to pick
•
Pick Moviebase if you want a single polished app to browse, filter, and discover in, don't care about anime as its own category, and are fine with undisclosed Premium pricing in exchange for an unlimited free tier today.
•
Pick Simkl if the goal is automated, cross-service tracking across TV, anime and movies in one catalog, and you want to know the exact price of every tier before you commit.
•
Neither answers what a household should watch tonight. Moviebase browses for one person; Simkl automates for one account. CouchReel's comparison pages cover that gap directly if it's the one you're trying to close.
