Cinopsys
Here's the key thing to understand: Simkl is a service, not just an app. It's the account and database that remembers everything you watch. The app you use to interact with it is a separate choice — and that's exactly the choice this page is about.
Keep Simkl as your backend; change the app you use it through. Cinopsys does full two-way Simkl sync, is 100% free with no ads, and adds widgets, deep stats and notifications — so your Simkl library gets a faster, cleaner Android home, and you're never locked in.
Why Simkl is worth keeping
Simkl tracks movies, TV and anime in one account, runs across web, iOS, Android, browser extensions, Plex and Kodi, and can import your history from dozens of other services. For anime in particular, it's one of the best backends going. None of that changes when you use Cinopsys — your Simkl account stays exactly where it is.
Where a better Android app helps
Simkl's own apps do the job, but the free experience carries ads, and a lot of Android users want something that feels more native and polished day to day. That's the gap Cinopsys fills:
- Full two-way sync — not a one-time import. Changes flow both directions, so Cinopsys and Simkl always match.
- No ads, no paid tier — the app you look at every day stays clean, free.
- Home-screen widgets, deep stats, advanced filters and upcoming-episode notifications, all included.
- Not locked to one service — Cinopsys also syncs Trakt, and runs standalone, so you keep your options open.
The best of both
You don't have to choose between Simkl and a great app. Use Simkl as your service — for its anime catalogue, cross-platform reach and extensions — and use Cinopsys as your Android front-end: free, ad-free, fast, and syncing both ways. If you ever want to add Trakt or go fully standalone later, Cinopsys already supports that too.
The verdict
Keep Simkl; upgrade the app. Cinopsys gives your Simkl library a polished, ad-free Android home with two-way sync, widgets and deep stats — and keeps your data portable across Trakt, Simkl and standalone. It's the Simkl client a lot of Android users have been waiting for.
Frequently asked questions
What is the best Simkl app for Android?
If you want a polished, fast Android experience, Cinopsys is hard to beat. It does full two-way Simkl sync, is 100% free with no ads, and adds home-screen widgets, detailed stats, advanced filters and upcoming-episode notifications — while keeping your Simkl account as the source of truth.
Does Cinopsys sync with Simkl?
Yes — full two-way sync. Mark something watched in Cinopsys and it lands on Simkl; update Simkl and it flows right back. Cinopsys is one of the few Android apps that offers genuine two-way Simkl sync rather than a one-time import.
Will I lose my Simkl data if I switch to Cinopsys?
No. Because the sync is two-way, your Simkl account stays intact and remains your backend. Cinopsys simply becomes a nicer window into it — and you can keep using Simkl's website and extensions alongside it.
Is Simkl free?
Simkl has a free tier that shows ads, plus paid VIP and PRO tiers that remove ads and add extras (PRO is free for members who use Simkl at least 20 days a month). Cinopsys is free with no ads, no tiers, so the app you look at every day stays ad-free regardless.
Is Cinopsys good for tracking anime with Simkl?
Yes. Simkl is one of the best services for anime, and because Cinopsys two-way syncs with Simkl, your anime, movies and TV all live together in one clean Android app.
