Image of the iTrick UI by Ariel Waldman.
I missed this talk, but when Ariel saw this slide she took a pic — and if you look close you can see iTrick‘s 2.5 interface where you can enter duration, paid (and amount if you paid/got paid), and check boxes for things like “jerker” “cocksucker” or “he took my load” and “swallows”, etc. You can also upload photos and rate their safety, make reminders like “bringing his boyfriend” and more. There are clearer, more detailed screenshots on their site.
Excellent.
