Whip Power Trainer
Badminton whip-snap trainer
Free · Designed for iPhone. Not verified for macOS.
Strap your phone to your forearm and swing — feel the snap crack the instant your brake is sharp.
Whip Power Trainer is a digital twin of the badminton whip-snap power stick. It turns your phone into a whip-snap trainer: strap it to your forearm or wrist, and as you swing, a real physics engine simulates a weight sliding inside the stick. Only a true "accelerate then brake sharply" whip makes the weight crack the end-cap with a crisp click.
Why it helps: power in badminton comes from the whip — a kinetic chain that accelerates and then brakes to fling speed into the racket head. Whip Power Trainer turns that abstract "snap" into feedback you can hear and see, instantly.
Features:
- Physics digital twin — a real engine that only rewards a genuine whip-then-brake
- Instant snap sound — a crisp click the moment your deceleration is sharp enough
- Adjustable weight — Light / Medium / Heavy presets plus mass, tube length, friction, threshold
- Score & curve — impact speed, peak angular velocity, time-to-peak, and a load-brake-impact curve
- Voice feedback — your rating spoken after each swing, eyes off the screen
- Auto-calibrated — the swing axis is detected from your motion; just strap on and swing
- Swing count & hit rate — every swing logged, with your snap hit-rate
Fully on-device: no account, no tracking. Sensor data is processed in real time and never leaves your phone.
