Three swings to a rally
Open the app
Your phone becomes the racket and quietly hosts the whole game — no account, no setup, no cloud.
Open the address it shows
Any browser on the same Wi-Fi becomes the court: laptop, iPad, another phone, the TV in your living room.
Swing
The first swing starts the match. Timing the golden ring earns a sweet-spot bonus.
On the court today
Badminton is free forever — unlock the rest of the arena.
Why it feels right
The ball goes where you swing
No buttons to memorize. Swing up for depth, chop a high ball for a smash, sweep sideways to place it — 100 Hz motion sensing, ~40 ms from wrist to screen.
Zero setup, zero accounts
The phone hosts the game over your local network. Nothing is installed, nothing leaves the room, nobody asks you to log in.
A real opponent or a relentless one
Five CPU tiers — from Rookie, who fumbles once every ten exchanges, to Unbeatable, a wall that digs everything.
Split-screen versus
Flip the match to Versus and a 4-digit room code appears on the big screen — Player 2 opens Smashphone, taps Join room, and types it in. The court splits like a co-op classic: each player gets their own camera and their own end of the arena.
Seriously: do not smash your phone
Grip tight, use a wrist strap if you have one, and clear the space around you. Phones fly further than shuttlecocks — and only one of them bounces.
