I've been using this app for years now and I really enjoy using it. it's easy to find shows and keep track of everything. I used it both in a continuous way, trying to keep consistency over the days and earn badges, but also in a more casual way and both are nice. since I started to use letterboxd again, I mainly use it for shows. I don't have any problem with the UX/UI and in general is neat. sometimes it's a bit slow or buggy, but could be due to the fact that I'm a beta tester.
