A question generator produces an on-demand question whenever a couple wants one, while a daily question app delivers a single structured prompt on a fixed rhythm as part of an ongoing relationship ritual.
The 36 Questions study is a 1997 psychology experiment that used escalating self-disclosure questions to generate feelings of closeness between strangers in a lab, not a formula proven to make two people fall in love.
A date night question is a conversation starter designed to shift a couple out of autopilot small talk and into an actual exchange, on a night set aside specifically for that.
The ideal question frequency for couples is roughly once a day or every few days, asked in small doses, rather than occasional long sessions that try to cover everything at once.
