SwiftCue Badminton

Not a Game. Not a Coach. A reaction training tool.

(SwiftCue is designed to make solo shadow practice less predictable.

Instead of knowing where your next imaginary ball is going, SwiftCue gives you randomized audio cues at changing intervals. You listen, react, perform the movement, and return to your ready position before the next cue.

The aim is simple: keep you reacting rather than anticipating.

The SwiftCue Training Cycle

READY
Start in your normal ready position and stay alert. The time between cues varies, so you cannot rely on a fixed rhythm.

REACT
Listen for the audio cue and immediately perform the corresponding shadow stroke and movement.

RESET
Return to your neutral position and prepare for the next cue.

Repeat the cycle throughout the session.

Important: SwiftCue is designed to be used primarily through audio. You should not need to watch the phone while training.

❓ Help - View instructions and guidance.

Section 2: Setting Up Your Drill

Before starting a session, use the Setup screen to choose how you want to train.

Start Simple

If you are new to the app, start with a simple drill to familiarise yourself with the prompts and required responses. Once comfortable, increase the complexity of your training.

Configure Your Drill:

1. Strokes Count
Set the number of cues for your training session using the STROKES COUNT slider.

For example, select 20 strokes for a short practice block.

2. Maximum Interval
Set the time between cues using INTERVAL (sec) slider. A lower value creates a faster training rhythm.

3. Training Variables
Turn SwiftCue training variables ON or OFF.

Side — Forehand / Backhand
Trajectory — High / Flat / Steep / Tumbling
Depth — Net / Mid / Deep
Target — Corner / Body
Direction — Straight / Cross

Fine-tuning

Free users can fine-tune the Side variable by adjusting the weighting between Forehand and Backhand.

Premium users can fine-tune all five training variables, giving them greater control over how the different training options are distributed during a drill.

Free: Fine-tune Side
Premium: Fine-tune Side, Trajectory, Depth, Target and Direction

Free lets you experience all five variables. Premium gives you control over all five.

4. Adjust the Balance
Use the − / + buttons to adjust the weighting of the available options within a training variable.

For example, for Side:

Forehand: 1
Backhand: 2

This gives Backhand a higher weighting in the random selection.

Premium: Save Your Custom Drills

Premium users can save their favourite drill configurations so they can quickly return to them later.

A saved drill can include your selected:

Stroke count
Maximum interval
Training variables
Variable weighting

Save a Drill

Once you've configured your drill, tap the Bookmark / Folder icon at the bottom of the Setup screen.

Load a Saved Drill

Open your saved drills and select the configuration you want to use. The saved settings will be loaded automatically.

Delete a Drill

Select a saved drill and choose Delete to remove it.

Maximum Saved Drills

You can save up to 10 custom drills at a time. If you reach the limit, delete an existing drill before saving another.

Section 3: Running a Training Session

Once your drill is configured, go to the Play screen.

1. Get Ready

Tap START and move into your training position.

Adopt your normal ready stance and listen for the first audio cue.

2. Listen & React

When you hear the cue, immediately perform the corresponding shadow movement.

For example:

“Forehand” → perform your forehand movement.

“Backhand” → perform your backhand movement.

3. Recover

After each movement, return to your neutral ready position and prepare for the next cue.

The delay between cues is randomized, so don't try to anticipate when the next cue will arrive.

⚠️ During training : Don't Watch the Screen

SwiftCue is designed to be used primarily through audio cues.

You should not need to look at your phone while training. Watching the screen can interrupt your ready position and reduce the realism of the exercise.

The visual court and ball representation are there to help you understand or review what happened — not to tell you where to move during the drill.

Audio

Make sure you can clearly hear the SwiftCue audio cues while moving.

Small wireless earbuds, the phone speaker, or a nearby Bluetooth speaker can be used.

Avoid anything that interferes with your movement or prevents you from hearing the cues clearly.

Premium: Video Recording

Premium users can optionally record their training sessions using the device camera.

Video recording is completely optional. You can use SwiftCue normally with audio cues without recording.

Starting Video Recording

1. Enable the Camera

Tap the Camera icon for the first time. SwiftCue will request camera permission.

Once permission is granted, the Camera icon turns blue, indicating that the camera is available.

2. Start the Camera Preview

Tap the blue Camera icon to activate the camera preview.

The icon turns amber and the preview covers most of the screen.

Use the preview to position your phone correctly before starting your training session.

The camera preview covers most of the screen when active. This is intentional — SwiftCue is an audio-led reaction and shadow-practice trainer. Once your camera is positioned, you should focus on the training rather than watching the phone.

3. Position the Camera

Once the camera is positioned, place the phone securely on its stand or tripod.

4. Start Training

Tap Play to begin the training session.

If the camera preview is active, video recording starts with the session.

Important: Video recording starts only when the camera preview has been activated before Play.

Recommended Camera Position

For the best recording, place your phone securely on a stable stand or tripod.

Place the camera in front of you.
Position it far enough away to capture your entire body, including your feet.
Keep the camera approximately at chest or upper-body height.
Make sure there is enough space around you to capture your lateral movement.
Use the widest practical framing that keeps your full movement visible.

This can be particularly useful for sharing your training video with a coach for movement and technique evaluation.

Section 4: Session Stats

The Cue Stats screen shows a visual summary of your most recent training session.

What You'll See

At the top of the screen, you can see:

Date — when the training session was completed
Strokes — the number of cues processed during the session

The centre of the chart shows the total number of strokes.

The multi-ring chart shows how your training cues were distributed across the five training variables:

Side — Forehand / Backhand
Trajectory — High / Flat / Steep / Tumbling
Depth — Net / Mid / Deep
Target — Corner / Body
Direction — Straight / Cross

Each ring represents one training variable, with the coloured sections showing the proportion of each option.

Using Your Stats

Use the results to see how your drill was distributed and decide whether you want to adjust your next session.

For example, if the Side ring shows significantly more Backhand cues than Forehand cues, you can return to Setup and adjust the weighting.

The same principle applies to Length, Position and Spin when using Premium fine-tuning.

Important: Session Stats Only

Stats represent your current/recent training session, rather than a long-term training history.

When SwiftCue is restarted, the session statistics are cleared.

If you want to review your results, check the Cue Stats screen before closing or restarting the app.

Premium: Video Review

If you recorded your session using the Premium camera feature, you can access the video from the Cue Stats screen for review.

Premium: Video Review & Storage

If you recorded your training session, Premium allows you to review the video from the Stats screen.

Use the recording to review:

Your reaction to the audio cues
Any hesitation or unnecessary movements
Footwork and recovery to your ready position
Stroke execution and movement technique

Video Storage

Recorded videos are stored on your device and can use significant storage space if they are kept over multiple sessions.

If you no longer need your recordings, use the Trash button to free up storage.

⚠️ Important: Delete All Videos

The Trash button deletes all videos saved by SwiftCue on your device.

It does not delete only the current or most recent video.

Once deleted, the videos cannot be recovered through SwiftCue.

Deleting videos does not delete your saved drills or your active session statistics.
