I started to use showly oss a while ago. It's similar to IMDb but uses trakt as a backend.

I use stremio with torrentio addon. It is basically a free streaming service if you have good internet. It also keeps track of the shows and movies you watch between devices and announces you when a new episode airs.

I found a decent alternative to Goodreads the other day called bookdigits. It’s a mobile app but pretty good. It has a sister site called screendigits.com for movies and films.

I started using tv time a few years ago before justwatch started, but sometimes I check it to know If I have to download or it is in the service streaming I am paying for.

Hobi is the best! It doesn't track movies only tv shows, but I'm using it for years now and it's such a great app, I bought the premium which is like $10 for life. I can't recommend it enough

I use series guide

I use Reelgood. I think it lacks a little on the recommendation side, but I really like the tracking. It also shows me when shows I'm tracking are coming back for new seasons.

SickChill seems promising for series.

TV Time is the best one I've tried so far, apps on iOS and Android + browser access.

I’ve been on Trakt.tv for a couple of years and nothing but happy. Love the scrobbler for Plex, very useful calendar. Has both recommendations based on what you’ve watched and trending to see what everyone is watching

A bit pricey
