Swing Like a Pro. Feel Like a Pro.
Searching for the perfect tennis swing tool to improve your game?
Meet SLAP FLAP — a patent-pending tennis swing training aid designed to help players build a correct, loose, low-to-high (topspin) swing through instant sound feedback.
SLAP FLAP clips onto your racket and turns it into a pro-level swing trainer in seconds, so you can train your swing anywhere, anytime.
What is SLAP FLAP?
SLAP FLAP is an on-racket swing training tool that helps players develop proper swing mechanics and muscle memory.
It works through real-time sound feedback, allowing you to hear when your swing is loose, well-timed, and properly sequenced — without needing a court, ball, or coach present.
Whether you’re a beginner, recreational player, or competitive athlete, SLAP FLAP helps you train the right motion, not just swing harder.
Trusted by players competing in USTA tournaments across the United States, SLAP FLAP helps build match-ready swing confidence before stepping on court.

Convert Any Racket to a Pro Swing Tool
How Does SLAP FLAP work?
SLAP FLAP uses a two-sound feedback system that responds to how you swing — not how hard. Every swing gives you immediate feedback (real-time auditory), helping you self-correct and repeat the right movement pattern.
1. Start by connecting SLAP FLAP to your Racket
🔧 Simple, secure setup in seconds — fits most racket sizes. Get started with SLAP FLAP
2. Feel the Two-Sound System (Your Guide to a Proper Swing)
🔊 First Sound — During the Swing (Low to High)
This sound happens during the forward swing as the racket accelerates upward.
It tells you that:
- You created natural lag
- Your swing was loose and relaxed
- The racket followed a low-to-high path (essential for topspin)
- Power came from weight transfer and rotation, not just the arm

This is the foundation of a modern topspin swing.
🔊 Second Sound — After the Swing (Finish & Reset)
This sound happens after the swing finishes, when the racket comes across the body and you reset to ready position.
It confirms:
- A full, relaxed follow-through
- Proper swing completion
- Balance and recovery
What Do the Two Sounds Mean Together?
Hearing both sounds in rhythm means your swing was:
- Properly sequenced
- Loose and fluid
- Low-to-high with correct timing
If a sound is missing, it’s not a failure — it’s simply feedback to adjust.
⤴️ SLAP FLAP encourages a natural low-to-high swing motion, essential for topspin and clean ball contact.
