Boop exists for one specific moment: you are thinking about someone you already know, and you do not know if reaching out would be welcome. Boop turns that hesitation into a small, consensual signal. You add the person manually by phone number, or by choosing them from your contacts. You send a Boop. They are told someone is thinking about them, never who. If they independently add you and Boop you back, names reveal at the same instant on both sides and a private chat opens. If they never do, nothing happens. There is no rejection screen, no awkward read receipt, nothing to take back.
Boop is not a dating app, not a discovery feed, not a place to meet strangers, not a social network, and not a feed designed to maximize screen time. It is a consent-first app for reaching out to people you already know. Reconnection with an old friend, family member, or former coworker is one use case among others: a crush, an ex, the person you keep almost texting.
Boop was built in Stockholm, by someone who got tired of the only options being silence or a cold "hey stranger" text years later. The product is intentionally narrow: one feature, one promise. Nothing is revealed unless it is mutual.
That is the whole purpose. Boop is not trying to grow into a social network. It exists so one small, honest thought has somewhere to go.
