Overview and Exclusive Features
SwingProfile is the world’s first technology that automatically detects, records and analyzes golf swings. You can film another golfer’s swing, or position the phone on a stationary spot such as a tripod or a golf bag to capture your own swing. Utilize the following options help analyze your swing:
- Instant Profile creates Golf Digest-style Swing Sequence from your swing video.
- Motion Trim records only the swing and deletes irrelevant footage.
- Auto Line instantly measures club shaft angle and draws shaft line.
- Dual Sync synchronizes two golf swings regardless of tempo differences. Perfect for side-by-side comparison.
- Twin Cam synchronizes a front and down-the-line view of your swings, side-by-side.
SwingProfile works on two camera angles: the Front and Down-The-Line (DTL) View. ‘Front-View’ displays the golfer face-on and DTL shows the player’s side profile and the target.
Hardware and Platform Requirements

Use Library to organize swings captured and edit golfer details, Settings for editing user profile and other settings.
Capturing Golf Swings
Select Capture from main menu then proceed accordingly:
|Filming Another Golfer
|Stand 10 feet away from golfer and apply back camera.
|Apply front camera. Lay down a reference club between the ball and center of your stance for down-the-line view, or across your feet for front view.
|Fit golfer just inside head and feet lines.
|Fit device to an iPhone holder.Station on golf bag or other stable surface at 10 feet away.Adjust camera to fit reference club to bracket on screen.
Press “Capture Start” icon to start capturing. Proceed according to border color.
Action according to border color code and live instruction on screen:
No Border Color
|Capture PauseTap to start capturing.
|Excessive Movement – Not Ready To CaptureThe golfer must initiate a proper swing with a 1-3 seconds pause at the address position to distinguish from a random practice swing.Other excessive movement caused by shaky camera or moving objects in the background will also hinder capture.
|Ready To Capture (single beep)The golfer may now perform a swing.
|Swing Captured (double beep)It then takes 3-6 seconds (device-dependent) to prepare for next capture.
Note that camera focus is locked while capture is switched on. To re-focus, tap capture pause icon to activate auto-focus, and then restart capturing again.
- Open, distant backgrounds – avoid moving objects, cluttered or close-range backgrounds.
- Keep clothes plain – ideally light top and dark pants.
- Smooth and swift swings.
- Hold camera with both hands to avoid shaking.
- Use a sturdy phone holder when filming yourself.
- Keep lighting level optimal – outdoor overcast produces best results.
- Apply Backlight Correction when encountering backlight problems at driving range.
- Fit golfer just inside the head and feet lines.
See Troubleshootingfor more details.
Position golfer’s head so it touches the top line and the feet the bottom bracket. For filming yourself, create a reference target by placing a golf club (such as a 7 iron) between the golf ball and the center of your stance for down-the-line view, or across your feet for front view. Adjust phone position so the golf club fits inside the bottom bracket of the grid. Experiment to find optimal position.
Toggle between front and back-cameras of the device (function not available to iPhone 3GS).
Automatic and manual exposure adjustment. When encountering backlight problems common in driving ranges, switch to manual exposure, tap on a darkened part of the image, and SwingProfile will adjust exposure accordingly. Repeat to find optimum exposure.
Toggle sound signal for capture. Single beep indicates SwingProfile is ready to capture; double beep indicates one swing captured.
SwingProfile provides single and dual views for swing sequence analysis, accessible via tapping on “user” and “compare”.
Single Sequence View
Displays golf sequence of the user’s swing. In this view you can tap on any key position view full size image and swipe screen to view next key position. Tap “fine tune” to adjust key positions.
Fine Tune Key Positions
Fine tune the frame number for each key position. Tap “reset” to reset to the original key positions.
Dual Sequence View
Display the swing sequence of the user and model side-by-side.
SwingProfile provides single and dual views for video analysis, accessible via the “User” and “Compare” icon. Simple navigation and drawing tools are available for indepth analysis.
Single Video View
Displays video of the user’s swing. Full navigation control and simple drawing tools are available for frame-by-frame analysis.
Dual Video view
Displays the user and model swings side-by-side. ‘DualSync’ technology is applied by default to synchronize two videos. Full navigation control and simple drawing tools are available for frame by frame analysis.
You can access Analyze Options from both the single and dual video screens.
|Determine play back speed
|Toggle continuous play mode
|Automatically synchronize two swings
|Measures shaft angle at address. If the shaft angle is from 20 to 70 degrees, a reference line will be drawn through it. If the shaft angle is more than 70 degrees, a vertical line will be drawn at the end of the shaft.
|Flip Player 1
|Flip player 1 left-right
|Flip Player 2
|Flip player 2 left-right
|Synchronize To Player 1 or 2
|In Dual Sync mode, determine which player is master / follower in terms of swing tempo.
The library organizes the captured (user) swings and model swings. User can select swings to analyze or edit. The default method for analysis is to compare a user swing to a model swing. SwingProfile however can perform ‘TwinCam’ simulation – simulating the effect of having two cameras for each front and down-the-line view – by placing a down-the-line (DTL) view to the left window, and a front view to the right window, using long tap selection. To select a captured swing
- Select “User” tab.
- Tap on “Select” to select swing. Single tab assigns the swing to the left window; long tap assigns to the right window.
- Tap “View Sequence” or “View Video” to start analysis.
To select a model swing
- Select the model tab.
- Tap on “Select” to select swing. Single tap assigns the swing to the right window; long tap assigns to the left window.
To delete a swing Swipe right on the row and press ‘delete’. To edit golfer details Tap on to edit golfer details. To select two user swings for ‘TwinCam’ simulation
- Select the user tab.
- Single tap on a down-the-line (or front) view swing to assign to the left window.
- Long tap on a front (or down-the-line) view swing to assign to the right window.
Analyze at either “Sequence” or “Video” view.

False-Detection and Troubleshooting
SwingProfile operates solely on video and is dependent on image quality (lighting, shadows, contrast, clothing). Random movements in foreground and background could be falsely detected as swings. To achieve optimal results, follow the simple rules below:
- Hold camera steadily with both hands to avoid shaky images. Use a climbpod or tripod when filming yourself for stability and convenience.
- Avoid moving objects in the background and cluttered backgrounds. These include moving branches and unwieldy clothing (such as scarfs) on a windy day, moving people at a party or moving cars near a busy road in the background.
- Keep clothes plain, ideally with light top and dark pants. Large stripes and patterns cause optical illusions and should be avoided.
- Avoid strong sunlight from behind golfer which darkens the image and casts a long shadow. Remedy this by turning golfer towards the sun (and swinging without a ball if necessary).
- Use Exposure Adjustment to reduce backlight problems common in driving ranges.
- Swing smooth and swiftly. Slow back swings are easily confused as practice swings.
- Avoid placing your driving net too closely as the net makes large background movement upon receiving the ball. Remedy by doing practice swing without hitting the ball.
- Fit golfer to grid by shooting approximately 10 feet away. Position golfer close to the head and feet line. This helps keep image size consistent across all captures.
- Ensure sufficient gray level contrast between the golfer’s clothing and background. Certain clothing color such as light gray and light orange are easily “camouflaged“ against green fairway and may cause non-detection.
