Bragging rights, done fairly
The leaderboard rates everyone from crew matches and filmed matches, then ranks by the cautious end of each rating, so a couple of lucky wins don't put a newcomer on top. Head-to-heads show exactly how you stack up against your regular rival.

- Head-to-heads for every rivalry
Honest limits
Nearby means nearby
Sharing works directly between iPhones in the same place, with the app open. It isn't a cloud group chat.
iPhone only
Everyone who wants results on their own phone needs an iPhone with iOS 26 or later. Others can see the share card.
No background sync
With no server, nothing updates by itself. Results reach friends when you share them nearby.
Allow Local Network
Both phones need Local Network access for the app, with Wi‑Fi and Bluetooth on. The same Wi‑Fi network isn't required.
Frequently asked questions
Is there a free badminton tournament app?
Badminton Sensei's Crew is free, with round robin, knockout and King of the Court tournaments, leaderboards and head-to-heads. There's no account and no subscription.
How does sharing work without the internet?
Results and cards are sent directly between nearby iPhones using Apple's peer-to-peer networking with encrypted sessions. Nothing passes through a server.
Which format should we play?
Round robin is fairest for 4 to 8 players or pairs. Knockout is quickest for bigger groups. King of the Court suits one court, odd numbers and people who want to keep playing.
Can I use it for doubles?
Yes. Sensei scores doubles as well as singles, and the leaderboard rates players from both crew matches and filmed matches.
Does everyone need the app?
No. One phone can run the night. Friends with the app can receive results; anyone can see a share card you send.
