FOR BINGERS AND SLOW WATCHERS ALIKE • Mark episodes, whole seasons, or an entire series as watched • Track rewatches without losing your history • Rate titles and jot down private notes • See how far you are through every season MOVIES, SHOWS, AND ANIME, TOGETHER Most trackers make you choose. Kaset keeps your films, series, and anime side by side, with rich detail pages: seasons and episodes, synopsis, ratings, cast, and artwork, all cached so they open instantly, even with no connection. DISCOVER WHAT TO WATCH NEXT Browse what's trending this week and add anything to your watchlist with a single tap. YOUR VIEWING, BY THE NUMBERS Insights turns your history into something worth sharing: total watch time, episodes and titles counted, movies vs. series, and how much of what you start you actually finish. NEVER MISS A RETURN The calendar keeps upcoming episodes for your shows in one place. SWITCHING FROM TV TIME? TV Time is shutting down. Bring your history with you. Kaset imports your watched movies and shows and detects anime automatically, so you don't start from zero. You can also import from Sofa, and export a full backup of your library any time.

FULLY IN ARABIC AND ENGLISH Built for both from the ground up, with complete right-to-left support and native Arabic typography, not an afterthought translation. Start tracking in seconds.
