So one of the benefits of a streaming service is the recommendation algorithm suggesting new shows to you. They’re not perfect but I have discovered great shows in the past because of it. So to replace that I’ve found a great app called JustWatch. It asks you to select what services you’re subscribed to so I just choose all of them, then select what shows I’ve watched and which I liked, and its algorithm suggests new shows to watch. You can also use it to track what episodes you’re up to, which I’m sure is great for people more organised and less ADHD than I am!
Disclaimer - I suspect this app is australian-centric, but there must be other apps out there for your country too.
I started to use showly oss a while ago. It’s similar to IMDb but uses trakt as a backend.
I use series guide
Just Watch is not region locked. I use it here in the Netherlands. If you go traveling you can switch your region to see what is showing regionally.
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.
