Voice-first: say "record", hear your feedback

Choose your coach voice – Robert or Sam – for spoken feedback. Voice commands are optional, and nothing listens until you tap the mic. Tap once to start a voice session, then say “record” before each shot – there’s no need to walk back to your device between swings. A listening indicator stays on screen whenever the mic is on. The session ends when you say “stop listening”, tap the mic again, lock your screen or leave the page, or after about 5 minutes without a recognised command. While a session is on, your browser’s speech service (Google on Chrome and Android, Apple on iPhone and Safari) processes the audio to pick out commands. Prefer buttons? Everything works without the mic.

📱

On-device body tracking

DESHANK uses MediaPipe body-tracking technology that runs entirely on your phone or laptop. No video or body data is uploaded to us.

◎

Four scored swing checks

Tempo – the rhythm of your backswing and downswing.
Head movement – how steady your head stays.
Hip sway – how much your hips slide instead of turning.
Posture change – whether you stand up or dip through the shot.

Each one is scored from 30 to 100, so you can see what to work on first.

⚡

Speed against your own average

See whether a swing was faster or slower than your usual, shown as a percentage of your own average. It’s a personal comparison, not a club-head or ball speed reading.

↻

Turn estimates

Rough shoulder and hip turn estimates help you see the shape of your swing. We show them as guides and don’t score them, because a camera alone can’t measure them precisely.

💡

Honest confidence flags

If the light is poor or you’re not fully in frame, DESHANK tells you the result is low confidence instead of pretending.

Works offline

After the first load, tracking, scoring and voice guidance work without a signal – handy on the range. Voice commands may need a connection, depending on your browser, but the buttons always work. [DEVELOPER TO CONFIRM HOW SUBSCRIPTION STATUS IS CHECKED OFFLINE.]
