Every won challenge generates a Victory Card - a shareable scorecard with the result, the stakes, and the bragging rights. Built for screenshots. Made for group chats.

STAKE ANYTHING

Challenges are more fun when something's on the line. Set custom stakes - a coffee, a dinner, a public apology in the group chat. CHLNG tracks it all.
