BadHub – find courts, join drop-in badminton sessions, and check in with a QR scan. All in one app.

Tired of scrolling group chats and counting "+1"s, only to find the numbers don't add up at the court? BadHub puts the whole flow on your phone — finding a venue, hosting a session, signing up, and on-site check-in — so every session actually happens.

FIND VENUES FAST 200+ badminton venues across Taiwan (sourced from Sports Administration open data). Search by city and distance, open the map and go. Missing your home court? Submit it and build the database together.

HOST A SESSION, FRIENDS JOIN IN SECONDS Set the time, venue, level range, and headcount. Publish, and players see it instantly and grab a spot. When it's full, a waitlist kicks in automatically — cancellations promote the next player and notify them. No more manual roster juggling.

QR TICKETS, SCAN TO CHECK IN Signing up generates a personal QR ticket (Ed25519-signed against forgery). Show it to the host, one scan and you're in. Who's arrived and who's missing — clear at a glance. Add it to Apple Wallet, too.

AUTOMATIC ROTATION One tap generates each round's matchups, balancing everyone's court time. The whole session sees the rotation board live.

SMART FILTERS Filter by skill level (18-level system), country/city/district, date range, starting time, free venues, and mixed-doubles needs.

CHAT, FRIENDS, CLUBS Every session gets a group chat. Add friends via QR, message directly, and join clubs to grow your badminton circle.

Fees are always paid to the host on site. The app is completely free — no payments, no in-app purchases.
