Help for your next performance

Support

CardSense is built to be simple in the moment. Prepare your effect first, keep the phone steady, and let the app stay in the background while you perform.

Quick start

Card Mirror

Choose a card back, select the reveal trigger, and hold the card steadily above the phone. For the most reliable recognition, use even lighting and keep the card fully visible.

Card Analysis

Place the card inside the camera guide and hold it still for a few seconds. Good contrast, a clean card face, and a little distance from the camera improve recognition.

Eye Reveal

Choose a photo, adjust the iris circle so it covers the eye, then start the performance. Swipe in the direction shown by the training guide to select the card.

Incoming Call

Assign callers to positions, choose the reveal delay, and start the performance. In training mode, use the numbered grid to learn where to swipe.

Trapped Card

Choose the entry direction, reveal trigger, card back, and gravity force. Training mode displays the grid and back navigation while you practise the motion.

Saved photos

Eye Reveal results are saved to your photo library. Trial results include a small Trial Mode · CardSense mark at the bottom of the saved image.

Troubleshooting

The card is not recognized

Move to brighter, even lighting; avoid glare; show all four edges; clean the camera lens; and hold the card still for several frames. Card Analysis works best when the card is not too close to the lens.

AR cannot find the card back

Use a physical card back with clear detail, place it flat in view, and move the phone slowly. AR tracking needs texture and light; plain or reflective surfaces are harder to detect.

The camera preview is black

Open iOS Settings, choose CardSense, and enable Camera access. Then close and reopen CardSense. Camera features require a physical device and do not work in the iOS Simulator.

Vibration or sound does not play

Check the effect settings, iPhone Silent Mode, volume, and haptic settings. Some haptic behavior is unavailable on the Simulator and varies by device.

CardSense Pro is not restored

Make sure you are signed in to the Apple ID used for the purchase, then use Restore Purchases in CardSense settings. App Store purchases are managed by Apple.

How do I change the language?

Open Settings → Language. Choose Automatic to follow the device language, or select a supported language manually.

Before contacting support

Update CardSense and iOS to the latest versions available for your device.
Restart the app and try the effect again in good lighting.
Include the app version shown at the bottom of CardSense Settings.
Never send payment details, passwords, or private photos unless absolutely necessary.
