I would like to know if any of you use an app or website/service to track your progress in series, or which movies you’ve seen.

The platform should also indicate where (streaming services) the movie/series is available

I’m currently using Justwatch but they probably sell a lot of user data, and some of the availability infos for some shows is wrong, and after contacting them to report this, they were of no help and didn’t understand what I asked. Seems like they only check the US catalog of the streaming services and don’t report it country per country, which is preferable.
