StampDat

The sports social network that keeps score. Every stamp locks at kickoff and gets graded by what actually happens. Your record can't be edited.

StampDat is a sports social network where every opinion goes on your permanent record. Post a stamp, a claim about a game, a player, or a season, with a stated way to know whether you were right. Other fans agree or disagree before kickoff. At kickoff the stamp locks and the vote freezes for good. When the game is over, the stamp is graded against reality and the result goes on your public record.

Plenty of apps have takes. This one keeps score.

STAMP IT Every stamp needs a resolution condition: "Lamar throws for 300," "the Celtics cover," "Judge hits 50 by September." A checker reads your stamp before you post and tells you whether it can actually be settled.

VOTE ON EVERYONE ELSE Agree or disagree with any open stamp. Your votes are graded too, at half weight, so you have a record from day one even if you never post.

A RECORD THAT CAN'T BE EDITED Hits, misses, and a score that rewards being right when the crowd was against you. Your history is permanent and public. That's the point.

A FULL SOCIAL NETWORK Follow the people whose records back up their mouths. Post photos and video, comment, quote, repost, and send direct messages. Not every post has to be a stamp. Post a talk when you just want to say something.

LIVE SCORES AND GAME CHAT NFL, NBA, MLB, college football, college basketball, the Premier League, and MLS. Every game has a sheet with the score, win probability, and a chat that stamps flow into.

COMPETE EVERY WEEK A weekly leaderboard, a question of the week, and community polls.

No gambling, no odds boosts, no real money. Just the tape.
