Every golfer has experienced it—setting up for a perfect shot only to watch the ball violently curve right (slice) or left (hook). These frustrating ball flights don’t just cost you distance—they cost you accuracy, confidence, and strokes.

The good news? Modern golf swing analysis apps make it easier than ever to diagnose why your ball curves and how to fix it.

In this guide, we’ll break down the causes of slices and hooks and show you how to correct them step-by-step using a swing analysis app.

Understanding Slices and Hooks

Before fixing the problem, it helps to understand what’s causing the ball to curve.

What Is a Slice?

A slice is when the ball curves dramatically to the right for right-handed golfers.

Main cause: An open clubface paired with an outside-in swing path.

What Is a Hook?

A hook is when the ball curves strongly to the left for right-handed golfers.

Main cause: A closed clubface paired with an inside-out swing path.

In simple terms:

• Slice = face too open
• Hook = face too closed
• Path determines how severe the curve becomes

A swing analysis app helps you see both the clubface angle and the swing path clearly.

How a Swing Analysis App Helps Fix Your Ball Flight

A high-quality swing analysis app gives you slow-motion video, on-screen swing lines, and real-time feedback so you can understand exactly what your swing is doing.

Here’s how it helps:

1. Detects Your Swing Path

You can use drawing tools to mark:

• Shaft plane
• Shoulder line
• Swing direction
• Clubhead path

This shows whether you’re swinging outside-in (slice) or inside-out (hook).

2. Measures Clubface Position

Frame-by-frame playback reveals:

• Is the face open at impact?
• Is it shut?
• What are your wrists doing?

These details are impossible to see at full speed.

3. Tracks Changes Over Time

Improvement comes from consistency.
Your app saves swings so you can compare:

• Before vs after
• Range vs course
• Different clubs
• Good swings vs bad swings

This helps build a repeatable motion.

How to Fix a Slice Using a Swing Analysis App

1. Check Your Setup

Use your app to record your address position.
Look for:

• Shoulders too open
• Weak grip
• Ball too far forward

Fix:

• Strengthen your grip slightly
• Square your shoulders
• Move ball position slightly back

2. Correct the Swing Path

On the video, draw swing lines to see if you’re cutting across the ball.

Fix:
Practice creating an inside-to-outside path by keeping:

• Trail elbow connected
• Club behind your hands during downswing
• Hips leading the turn

3. Square the Clubface at Impact

Analyze the moment of impact frame-by-frame.

Fix:

• Rotate your forearms naturally
• Ensure your lead wrist is slightly bowed
• Keep grip pressure relaxed

Your app will show if the face is less open each time.

How to Fix a Hook Using a Swing Analysis App

1. Check Grip and Alignment

Record your setup to confirm:

• Grip isn’t too strong
• Shoulders aren’t closed
• Ball isn’t too far back

Fix:

• Neutralize your grip
• Square your stance
• Move ball slightly forward

2. Straighten Your Swing Path

Your app will show if your club is swinging too far inside-out.

Fix:

• Keep the club more in front during takeaway
• Feel like the club is traveling slightly left after impact
• Rotate through the shot instead of flipping your hands

3. Open the Clubface Slightly

A hook comes from a closed face. Your app will catch it.

Fix:

• Ensure the clubface is square at waist-high
• Maintain a flatter lead wrist
• Don’t let hands release too early

Drills You Can Practice Using a Swing Analysis App

1. Swing Path Gate Drill

Set two alignment sticks and record:

• For slices: swing inside-out
• For hooks: swing outside-in (slightly)

Your app will confirm your path instantly.

2. Impact Position Freeze Drill

Pause at impact and take a screenshot to check:

• Clubface angle
• Hips open
• Shaft lean
• Weight shift

3. Lead Wrist Control Drill

Film your wrist angles to ensure:

• No cupping (slice)
• No excessive bowing (hook)

Final Thoughts

Fixing slices and hooks doesn’t have to be complicated. With a swing analysis app, you can finally see what your swing is doing instead of guessing. This clarity helps you make faster, more accurate swing adjustments and build a consistent, repeatable motion.

Whether you’re a beginner trying to keep the ball in play or an experienced golfer lowering your handicap, using technology is one of the smartest ways to improve quickly.
