The apps hadn’t been so thoroughly ruined by Match Group yet. OKCupid used to publish interesting detailed reports about dating habits. Plenty of Fish wasn’t full of bots and scammers. The apps that charged you for basic features were largely avoided. The experience was weird and new.
The dating app landscape as it is now is basically just whichever is the latest one until Match acquires it.
This and the Send Me to Heaven app (throw your phone as high as you can, higher height means higher score) were two of my favorite early apps clearly designed to mess with people buying expensive devices as status symbols.
