Taiga is really convenient, it's a desktop app that uses and syncs your MAL/AL/Kitsu list. It recognises when you're watching an episode (either through an official streaming site, or downloaded) and updates your list (can also be done manually in one click), it can also set your discord status as "watching XXX", which I find interesting. The interface is basic but fast, it's easy to browse your anime by score,... Source: 6 months ago

I used to pay for anime services, but they're all just so bad in their own ways like trash sites or censorship that I canceled and started yarring. If you're not afraid to set sail and use a VPN (which I always recommend), you can use something like taiga.moe which not only lets you connect to a tracker like anilist, but also lets you search torrents for individual episodes and complete seasons.

I just use a program called Taiga that automatically syncs with my AniList account when I watch stuff on my computer, it adds started and finished date, etc. And AniList has a pretty rich stats page if that's your thing. Source: over 1 year ago

Basically Taiga is a open source app to keep track anime shows you have watched and update your list in an online DB like Myanimelist/Anilist, etc. Source: over 1 year ago
