Do you ever get out of a movie and say to yourself, I'm up for one more? Well, Double Feature Finder is for you. Find movies whose endings and beginnings match up perfectly so you can make your own double features. Maybe even a triple feature! Of course, you should buy tickets for all the movies you see. Never sneak into movies.

Four films, one card, ready to post. lastfour reads your public Letterboxd diary and turns your four most recent watches into a share card built for Instagram — Stories, feed, or square. No login, no new account, just your username. Enter any public Letterboxd username and lastfour pulls the latest diary entries automatically, refreshing each time you open the app. Posters, director, runtime and genre are pulled in from TMDB so every entry looks like it belongs in a real archive, not a screenshot. Star ratings, likes and rewatch marks carry straight over from your diary, so the card reads the way your log does. Choose a background pulled from one of the four posters, blurred or sharp, or drop in a solid colour instead. Cards render in four ratios — square, 4:5, 9:16 for Stories, and widescreen — with layout adjusted automatically so nothing gets cropped badly. Share in one tap to Instagram or hand it to the system share sheet for anywhere else. Add the home screen widget and your last four watches, posters and ratings included, sit on your home screen without opening the app. lastfour is an independent app that reads a public Letterboxd profile via RSS. It is not affiliated with, endorsed by, or sponsored by Letterboxd or TMDB. Link your username and see your diary as a card.

Verdict
The clearest difference is device support: Double Feature Finder at 3 against lastfour's 1. Double Feature Finder also leads on iOS requirement (15.1 vs 18.0). On price, ads and in-app purchases there is nothing between them.
