Publisher Description
Open the app. A bout is already live, and everyone watching is scoring it in real time.
Welcome to Internet Fight League.
It started as Kayyo, built to train fighters. This is where that training was always headed.
IFL is live combat sports for the internet age. Real fighters. Real bouts. And a crowd that doesn't just watch. It decides who wins.
WATCH
Bouts from around the world, streaming live 24/7. The hottest fights float to the top of your Feed. Boxing, MMA, Muay Thai, BJJ, wrestling, all of it.
JUDGE
You're the judge. Score every round, vote live, and watch the fan verdict swing with every exchange. On IFL, the crowd crowns the winner.
DISCOVER
The world is your arena. Open the map and see real fighters near you. Filter by style, weight, and division. Find your next opponent down the street, then challenge them.
RANK
Win bouts. Take territory. Climb. One leaderboard ranks every fighter across every discipline. A W is a W. Pound for pound, by weight class, in your city or worldwide. There's a number next to your name. Make it smaller.
COMPETE
This is what the training was for. Match with an opponent, lock in the rules and the gear, coordinate the meetup, and go live with one tap. Fight. Get judged. Move up.
WHAT MAKES IFL DIFFERENT
. The crowd decides. Fans score and vote every live bout.
. Real opponents near you, not seeded bots.
. One leaderboard, every discipline. A W is a W.
. Live POV broadcasting, straight from your phone.
. Geared up, never bare knuckle. Gloves and a mouthguard on every striking bout, shin guards for newcomers.
. 18+, ranked, and built for people who actually compete.
Privacy comes standard. Your map location stays approximate until you choose to match. Bout details stay between you and your opponent.
You trained in private. Now find out in public.
Kayyo built the fighter. IFL is the arena. Step in.
Version History This isn't an update. It's a new sport.
