Peer skill ratings
After a match, you rate the people you played with. One tap each, under thirty seconds. Those ratings settle into a profile that is genuinely yours rather than a guess.
Teams, sorted before kick-off.
Halbreven is a closed app for the group of people you already play with every week. It picks fair teams, remembers who actually turned up, and keeps a record of it that follows a player from season to season.
The problem
Most amateur teams run on a group chat
Somebody posts "Sunday 10, who's in?". Twelve replies arrive over three days, four of them are jokes, two people say maybe and never come back. On the morning, one person scrolls up trying to count. Teams get picked by whoever shouts loudest, and they are lopsided about a third of the time.
Nobody remembers that the same player has said yes and not shown up four weeks running, because a chat thread has no memory. It scrolls.
Halbreven replaces that thread, and adds three things a chat app cannot do.
Automatic team balancing
The app splits whoever turned up into even sides using those ratings and the positions people actually play. It takes a second, and nobody has to be the one who picks last.
A reputation layer
A trust score that falls fast when you say yes and do not show, and recovers slowly when you do. Yellow and red cards for the things a group already argues about. Visible, so the group can decide.
Why build it this way
Seven rules that decide everything else
These are written down before features are, and they are the reason this is not another social sports network. If something breaks one of them, it does not ship — that has already killed ideas that were otherwise good.
P1
Closed by default
No public profiles. No search for people or groups. You get in because somebody handed you a code.
P2
Rating has to be fast
A full post-match pass in under thirty seconds. Complexity kills participation, and a rating system nobody uses is worse than none.
P3
Reputation is asymmetric
Trust falls fast and recovers slowly, the way a credit score does. That asymmetry is the whole mechanic.
P4
Cards inform, they never enforce
The app will not ban anybody. It shows the history and the group decides what to do about it. People, not software.
P5
Sport only
The timeline is for the game. Everything else belongs in the chat people already have.
P6
Free for players
No paywall on anything that matters. If a group has to pay to see who is coming on Sunday, the product has failed.
P7
Ratings are anonymous
You see your own scores. You never see who gave you which one — not as a player, not as an admin, not in any export.
Why P7 is load bearing
This app is for friend groups. If Ardit can see that Blerim rated him a four, it has manufactured a real argument out of a Sunday kickabout. The whole premise depends on aggregation providing cover, which is why it is enforced in the database rather than in the interface. How that works.
Who it is for
Twenty-one sports, ten playing surfaces
Anything where a standing group turns up, splits into sides on the day, and plays for a score. That is a much wider net than football, and the app draws each sport's real playing surface rather than a generic rectangle.
