"I prefer my own memory to paper. It works hands-free while driving, works without light late at night, and it’s waterproof in the shower. I especially like the way it improves everything I put into it. I have missed an occasional appointment. Perhaps that’s an improvement too."
I made a private web app — a glorified list really — that allows you to type in a movie to add to a watchlist, and then later you can mark an item as watched.
It just keeps track of the movies in your list, counts of watched and unwatched movies, the day you added a movie, marked a movie as watched etc.
Nothing sophisticated or smart. No pictures. Just a dumb boring list. Something I coded up on a boring Sunday.
Only me and a handful of friends use it.
Although it's out there on the internet (hosted on a cheap DigitalOcean droplet) and is open-source, I'm deliberately not sharing it here because it's not quite ready yet for the potential hug of hacker news:
I don't really keep track of it. The only tool I am using is the IMDB top 250 where I can click/rate movies.
It's not really because I like to keep track of everything, but I found out that the 250 list is actually solid, I watched some movies as far 1920s and enjoyed it. So I am going through them all, broadening my tastes.
