We're working on a few improvements to help you keep track of anime sequels, prequels and next to watch seasons that are not yet on your watchlists.

Two things shipped today, both anime only, both built on the anime you have already marked as Completed.

1. A new list "Not in My List" in My Anime (experimental, in V2 Beta watchlist)

A new list in your anime watchlists that shows related anime missing from every one of your watchlists. 3 different filters are available right now in this watchlist, all of them are based on your completed anime:

• Prequels = everything that comes before an anime you completed
• Next seasons = the whole rest of the run, so finishing season 1 also surfaces seasons 3 and 4
• Next sequels = only the immediate next step forward from each completed anime

Anything already in one of your watchlists is filtered out, so what's left is genuinely missing.

Find it under My Anime > Not in My List, or jump straight in: https://simkl.com/my/anime/?nim=sequels (with PRO or VIP access)

Also supports saving custom views and sorting with Custom Layout for this list.

2. Sequels added automatically (PRO and VIP) after watching the last episode. Finish the last episode of an anime, or move it to Completed, and its sequel is added for you:

• Already airing, goes to Watching
• Not aired yet, or an anime movie, goes to Plan to Watch
• Already in one of your watchlists, left exactly as it is

It's on by default and it only touches anime. Large imports and backfills are skipped, so syncing an old library won't flood your list. Turn it off any time: https://simkl.com/settings/pro/

Both are new and experimental, so tell us what looks wrong and we'll fix it in #chat-about-simkl on our discord https://discord.gg/u89XfYn.

Made to help you navigate anime seasonals, specials, movie sequels and prequels.

Future things on to-do: virtual checkmarks in anime for related anime seasons to be visually similar to Western TV Series.

Available now for PRO and VIP members with V2 Beta access.

If you rewatch movies or shows, you can now pull that rewatch history over from Trakt with the correct dates.

How to do it:

1. Head to https://simkl.com/apps/import/trakt/ and connect Trakt if you haven't already.
2. Pick "Import from Trakt once, without auto import."
3. Choose Option 5, "Import just rewatches."

What it does: It reads your full Trakt play history and finds everything you watched more than once, then adds those as rewatches on the matching movies and episodes, each with its real watched date. It works for movies and for individual TV and anime episodes. It's also smart about noise: multiple plays within a short window count as a single watch, so accidental double check-ins won't turn into fake rewatches.

Already imported from Trakt before? This is made for you. Option 5 only adds rewatches to shows and movies that are already in your SIMKL watchlists, and it leaves everything else untouched. So if you did a Trakt import in the past, just run Option 5 now to layer your rewatch history on top. If you're brand new, run your normal Trakt import first, then come back and run Option 5.

Happy rewatching. 🍿

>Note: Keep in mind that we're currently experiencing a high amount of new members coming from from TV Time, so the import function may be temporarily available only to PRO/VIP supporters.

An update on the https://www.reddit.com/r/Simkl/comments/1ukw725/tv_time_is_officially_dead_as_of_today_will_be/

Over the last few days, we've pushed multiple improvements to TV Time import at https://simkl.com/apps/import/tvtime/

If you have previously done an import and saw some movies that could not be detected (due to movie title year mismatches in TV Time export) or you had watch time imported on the same day, you can now re-import it again for newer match models.

Alternatively, you can clean your account data at https://simkl.com/settings/login/clean-or-delete/ and do a fresh import

If you're still having some difficulties with import, don't forget to try from a computer and not a mobile phone, and disable any Adblock extensions or Adblock DNS\VPN which may block the uploads.

If you see any additional improvements we can make or if something isn't working for your zip file, do let us know on Discord https://discord.gg/u89XfYn or through https://support.simkl.com

Calendar Update: all your episodes are back at https://simkl.com/my/calendar/

Some of our members noticed that episodes from your Plan to Watch and On Hold shows were getting trimmed on the calendar after previous calendar updates, showing only season premieres and finales.

As we found out that you may rely on these to add new episodes do download que without watching, we've changed that.

The calendar now shows every episode by default, for all your shows, whatever their status.

Still prefer the cleaner, less cluttered view? You can opt back into it anytime:

- Tap the new ⚙️button next to 🔥on any calendar

- Pick "Only premieres and finales" for your Plan to Watch & On Hold shows

- You can set your First Day of the Week right there too

All of it also lives under Settings → Calendar.

Thanks to everyone who spoke up about this. Keep the feedback coming on our discord https://discord.gg/u89XfYn and https://support.simkl.org/

Hey Developers,

Our developer docs have lived on Apiary for years. Oracle is sunsetting Apiary in October, and Apiary's been going down for hours at a stretch lately on top of that, so we used the forcing function to finally do what we'd been putting off: redo everything from scratch. Honest reason it took a few months is that once we started checking the old docs against the actual API, we found a lot more drift than we'd like to admit. What was supposed to be a content move turned into a top-to-bottom audit.

Anyway, the new docs are at api.simkl.org (or just hit api.simkl.com if that's easier to remember, it'll redirect you). We're pretty happy with how they came out.

Some of what you'll find there:

• Detailed guides for the workflows people actually build: Sync, Scrobble, Search, Anime, Deep linking, Mark as watched, and more.
• All three auth flows properly walked through: OAuth 2.0 for server-side web apps, Public PKCE for mobile / SPAs / browser extensions / desktop binaries, and PIN flow for TVs, consoles, CLIs, and media-server plugins.
• Conventions pages that explain the cross-cutting stuff Apiary never covered: Headers, Pagination, Dates, Watchlist statuses, Null values, Images, CORS, and more.
• Interactive try-it-now playground on all 48 endpoints. Drop in your token, hit Send, get a real response back.
• Copy-paste examples in 16 languages: curl, Python, JS/TS, Kotlin, Swift, Java, Go, C#, PHP, Ruby, PowerShell, C/C++, and more.
• LLM-friendly: every page can be copied as raw markdown or opened straight in Claude / ChatGPT / Cursor / VSCode. Full-site llms.txt is published too.
• Full OpenAPI 3.1 spec: every endpoint and every response shape, verified against the live API. Point your SDK generator at it.

And honestly we're stoked to be shipping two new things along with the new API docs:

API Analytics: every registered app now has a built-in live request log, so you can see exactly what your code is sending. Last 24 hours of individual requests, with edge/origin status codes, latency, burst detection for retry loops, and CSV export. Useful for diagnosing OAuth wrappers, sync loops missing date_from, and silent 4xx errors your client never surfaces. Open it from your app's row in your developer dashboard → Debug.

Rewatches: POST /sync/history?allow_rewatch=yes now tracks separate viewing sessions on items the user already finished. Same data that powers simkl.com's Rewatches panel. Up to 50 sessions per movie, show, or anime, with proper session IDs you can resume, server-side auto-detection (or force it with is_rewatch: true), and lifecycle statuses (active / completed / closed). Available for Simkl Pro and VIP members; free-tier callers get a silent no-op so existing apps don't break.

Heads up: the Rewatches API is still in early testing and the shape may change as people start building against it. Drop your suggestions and thoughts in our Discord; your feedback will shape where it lands.

Try the new docs. See if the workflow you care about is covered. Tell us what's broken, wrong, or unclear. Suggest the features you've been quietly waiting for. We're on Discord and we read everything, and the changelog is live if you want to follow along.

Thanks for being patient with us through the rebuild. The stuff people have built on Simkl over the years is kind of wild and we want to keep enabling more of that.

Just pushed a batch of calendar improvements:

Bug fix - Time sort now works on first load. Sorting by Time used to silently fall back to Rank order on page refresh — you had to click Time again to actually get time order. That's fixed. Also fixed: anime episodes that air late in JP time were sometimes ordered wrong within a day cell because of timezone conversion crossing midnight. Time sort now consistently shows each day in ascending hour:minute order.

The "NEXT" badge is more accurate. The indicator that highlights today's next-to-air episode now correctly picks the right episode, even for shows whose local-time airing crosses midnight relative to the broadcaster's timezone.

Less noise for shows you're not actively watching. For shows on your Plan to Watch, On Hold lists, the calendar now only shows season premieres (S01E01, S02E01, etc.) and finales (mid-season, season, and series). Shows you're Watching or have Completed are unchanged — you still see every episode. The idea: if you haven't started a show, you probably don't want every weekly episode cluttering your view — just the milestone episodes that help you decide when to dive in.

New "Binge!" label on finales in Plan to Watch and On Hold. Season finales, mid-season finales, and series finales now display a "Binge!" tag next to the air time — a nudge that the season just wrapped and you can marathon it.

Don't forget it's Georgie & Mandy's First Marriage 2-part season finale today!

We have added a new Parents Guide section to about 100,000 shows and movies on Simkl, right under Cast & Crew.

For supported titles, you can now get a quick content overview before you press play:

• Age rating when available
• Five content categories: Adult Themes, Violence & Gore, Profanity, Alcohol, Drugs & Smoking, and Frightening & Intense Scenes
• Color-coded severity from None to Severe
• Intensity score for each category
• Click any category to see the scoring distribution and read specific comments (if there are any available)

Whether you're planning a family movie night or just prefer to avoid certain types of content, the Parents Guide gives you a comprehensive breakdown of what to expect before you hit play.

You can find the new Parents Guide section on any TV show or movie page, right below the Cast and Crew.
