## What is Badminton Smash Power Trainer?

Hear the snap when your swing is right.

Strap your iPhone or Apple Watch to your forearm and swing like a smash. A physics engine simulates the weight inside a whip-power stick: only a real accelerate-then-brake swing makes it crack. Every swing gets a speed, a grade and a voice call-out, so you know instantly whether that rep counted.

FIND YOUR SPEED KEY
• Speed analysis compares your fastest and slowest swings and names the one thing that makes you faster: forearm rotation, rotation speed, time to peak force or brake sharpness
• Research-based tips and a drill for your next session

SEE EVERY SWING
• Swing detail with a 2D phase curve and a 3D path you can rotate
• Session speed chart, plus a daily progress chart for each weight
• History keeps your recent swings

COMPETE
• Leaderboards for each weight, filterable by country, with rank medals to climb
• Optional Sign in with Apple keeps your name and records when you switch phones

TRAIN YOUR WAY
• Light, Medium and Heavy weights for beginners to advanced players, or tune mass, tube length and friction yourself
• Snap sound, voice feedback and Apple Watch haptics
• Music and videos from other apps keep playing while you train
• Apple Watch app for hands-free training
• 13 languages

Great for smash, clear and wrist-snap practice at home, at the club or anywhere.

Free to use. An optional one-time purchase removes ads.
