Detroit. Your community starts here.
Always have someone to play.
Korta connects you with Detroit players at your level, helps you set up the hit, and tracks a rating that moves with every match.
Free to join. Detroit unlocks at 200 players.
Less group text.
More tennis.
Your game, in focus.
Korta runs gradient Elo and moves your number after every match. Self-rating can’t survive contact with real results.
- Updates after every match. No annual reshuffle.
- Beat someone above you and it climbs faster; lose to someone below and it drops.
- New numbers move fast, then settle as you log matches.
- Both players confirm the score. No self-reporting.
An opponent tonight.
Nearby players, close to your level. Go from “want to play” to a court booked in a few taps.
A match by Friday.
Send a request. They pick the time and the court. You just show up.
A rating by Sunday.
Win or lose, your number moves. Beat someone higher-rated and it climbs faster. That’s the whole game behind the game.
When does Detroit open?+
The moment 200 players are on the list. Everyone on the list gets their invite at the same time.
Why join the waitlist now?+
Because Korta is only as good as the number of players on it. Every signup gets Detroit closer to 200, and a full list on day one is what makes someone at your level, actually nearby, actually there when you open the app.
How do you know how good someone is?+
You tell us your NTRP when you sign up. That seeds your number, and it stays marked self-rated until matches verify it. After that it’s all match results: beat someone above you and it jumps, lose to someone below and it drops. New numbers start a little loose and tighten up fast as you play.
Is this really coming to Detroit?+
Yes. That’s what this list is for. Detroit unlocks at 200 players. We’d rather open one city full than twenty empty.
Is it free?+
Free to sign up. Free to log matches. If we ever add paid features, the core of finding a hit and logging your matches stays free.
Who’s building this?+
Two of us. Both in Austin, where Korta started. Both on the court more than at a desk.
Detroit unlocks at 200.Be one of them.
199 more and Detroit unlocks. Everyone on the list gets their invite at the same time.
The day Detroit unlocks, you open Korta and there’s a 3.5 fifteen minutes away who’s actually down to hit. You play Thursday.
No group text roulette. No driving across town to find out the 4.0 plays like a 3.0.
That’s what the list is for.
