Hi, I'm George. Making a dating app without swiping

Hi everyone! I'm making FiliFili, a dating app where nobody swipes: it finds a few people who fit you both ways, and photos start hidden and sharpen only when both people agree. It's my first product, so I'm mostly here to learn from people who've shipped before, and I'll be reading launches and commenting.

What's one thing you wish you'd known before your first launch?
