I really like the app for my personal reading tracking. Been using it for a couple years, and this year (?) there was a huge update that improved it a lot (better UX/UI and statistics if I'm not mistaken).

It's mostly an app that does what it should, but not more, and gets out the way, which is awesome.

Works well for keeping track of books I've read an yearly reading goals

This project was actually my exit way from Goodreads. Unlike another commenter, I found virtually no issue with searching for books in European languages. All the statistics which GR offers are available, and you can easily import your books to the app. And of course, no ads, zero trackers and open source.

The only caveat is the social aspect, since this is an offline tracker.

Edit: If you have any concerns, hop on the matrix community where the dev is active.

I've been using it for a few months now and I think it is great. I can't compare it to Goodreads and others because I have not used them, but it is pretty straight forward to add a book, give a rating and write a review. I like the UI a lot too.

The only problems I have with it is that the API they use is not very good for adding books in my native language and that backup is manual and I don't know if it has integration with Android's automatic backup.

Also, it would be nice to be able to write multiple reviews for the same book, it would be cool to see how much my vision and opinion of a particular title changed over time. I should probably suggest this feature on their github.
