Nick Jaussi was so kind to create a program overview for the Pornfilmfestival Berlin, where you can remember which films you want to see. Simply tap a box to mark the entry (it will then change color) or tap again to remove the mark. Your selection will be stored on the device, which you use to visit this list.
If you want to try it out, see here: https://pornfilmfestivalberlin.de/memo/2024/
