Cinopsys
Simkl is the account that remembers what you watch — and it's especially good for anime. Connecting it to Cinopsys keeps Simkl as your backend while giving you a faster, cleaner Android app to use it through, with full two-way sync.
- Install Cinopsys → Settings → Sync & Backup → select Simkl → authorize.
- Sync is two-way — not a one-time import. Movies, TV and anime stay matched.
- Works with a free Simkl account, and Cinopsys is free with no ads.
Connect Simkl in 5 steps
-
Install Cinopsys
Grab Cinopsys free from the Google Play Store and open it. Everything works before you sign in to anything, so there's no rush.
-
Open Sync & Backup in Settings
Head to Settings → Sync & Backup. Under "Where your library lives," you'll see three choices: This device only, Trakt and Simkl.
-
Select Simkl
Choose Simkl — it "syncs to your Simkl account, across all your devices." Cinopsys sends you to Simkl's official website to sign in, so your password is only ever entered on Simkl, never in the app.
-
Sign in and authorize
Log in to Simkl and approve access for Cinopsys. You'll be returned to the app automatically.
-
Let the first sync run
Cinopsys imports your Simkl movies, TV and anime, with their history, ratings and lists. After the first pass, changes flow both ways and stay matched.
Simkl can import from some services, but those links are often one-way. Cinopsys does genuine two-way sync, so it doesn't matter whether you update Cinopsys or Simkl — the other keeps up. Read more in the best Simkl app for Android.
Great for anime
Because Simkl is one of the strongest backends for anime, connecting it is the easiest way to track seasonal and classic anime alongside everything else you watch. If that's your main goal, our guide to tracking anime on Android picks up from here.
You're set
That's two-way Simkl sync done. Prefer Trakt, or want to switch later? You can change where your library lives anytime — or run Cinopsys standalone and back up to Google Drive instead.
Frequently asked questions
Do I need Simkl VIP or PRO to use Cinopsys?
No. Cinopsys works with a free Simkl account, and Cinopsys itself is 100% free with no ads. Simkl's paid tiers only affect features on Simkl's own apps and website.
Is the Simkl sync really two-way?
Yes. Mark something watched in Cinopsys and it lands on Simkl; update Simkl and it flows back. Cinopsys is one of the few Android apps with genuine two-way Simkl sync rather than a one-time import.
Will connecting overwrite my Simkl data?
No. Your existing Simkl library is imported and kept as your backend, and changes are merged in both directions rather than wiped.
Is Cinopsys good for tracking anime with Simkl?
Yes. Simkl is one of the best services for anime, so connecting it brings your anime alongside your movies and TV in one clean app.
