Most social apps start with a profile and hope chemistry follows. Nerd flips that. Answer two-choice Decks about the things you love and see exactly who thinks most like you with an Overall Answer Match score out of 100. The binary choice is the matching engine, not a warm-up. Users create their own Decks, chat in-app, follow each other, and earn XP, badges, and streaks that keep them coming back. No algorithms. Just curiosity. Free on iOS and Android.
