You can't improve what you can't see.

No feedback on contact quality

You feel a mis-hit, but you don't know exactly where it landed or why. There's no data — just frustration and guesswork.

Coaches can't watch every swing

Even in lessons, your coach sees a fraction of your shots. Between sessions, you're on your own with no way to measure progress.

Power without precision is wasted

Most players think swinging harder wins points. The truth: off-center hits lose 40%+ of their energy. Clean contact beats raw power.

Sweet spot improvement from 31% to 64% over 4 weeks
Everything your paddle
never told you.
Nine piezoelectric sensors and a 6-axis IMU capture every hit down to ±5 mm. The app turns raw sensor data into stuff you can actually act on.
42%
sweet-spot rate

Average recreational player's center-hit rate. Pros hit 80%+. Most rec players don't even know they're mis-hitting.

Sweet-Spot %

Your most important number. See what percentage of hits land in the center zone — updated live after every shot. Set goals, track trends, watch yourself improve.

Hit-Location Heatmap

A real-time density map of where every ball lands on your paddle face. Filter by forehand, backhand, or force level to find hidden patterns in your game.

Per-Hit Force

See the impact force of every shot in Newtons. Track your average power, compare sweet-spot force vs edge-hit force, and understand the link between contact quality and energy transfer.

Coaching Tips

After each session, the app analyzes your miss patterns and tells you exactly what to fix. Think of it as a coach who watches every rep.

8 rule conditions · Trend tracking
9 sensors. 16 bytes. Instant insight.
Ball strikes paddle. Sensors fire. Data flies to your phone. You see the result before you reset for the next point.
1

Sense

9 piezoelectric discs bonded under the carbon-fiber face detect impact force, location, and timing with sub-millisecond precision.

2

Process

The onboard nRF52840 MCU computes hit position via weighted centroid, measures total force, and classifies your swing — all in under 15 ms.

3

Deliver

A 16-byte BLE packet hits your phone instantly. The app updates your heatmap, sweet-spot %, and force readout before you finish your follow-through.

Hit Density Map

See where every ball lands. Filter by forehand, backhand, or force level.

It finds your patterns,
then tells you what to fix.
The app looks at your force, swing type, and accuracy together and tells you what to change mechanically.
Hits cluster high

Paddle face too open at contact. Close your wrist 5–10° and focus on meeting the ball in front of your body rather than reaching up.

Force drops off-center

Edge hits are 40% weaker. You're likely off-balance or reaching. Focus on footwork — move your feet to the ball instead of extending your arm.

Backhand miss bias

Backhand accuracy 15pts below forehand. Lead with your shoulder turn and keep your elbow closer to your body through contact.

Improving trend ▲

Sweet-spot rate up 5+ points. Your center-hit rate is climbing. Keep doing what you're doing — consistency is building.

It's still a great paddle.
