Once powered on and optionally paired, simply touch the stylus tip to your iPad screen to begin writing, drawing, or navigating. The stylus offers pixel-perfect precision and low latency for a smooth experience.

5.2. Tilt Sensitivity

The stylus supports tilt sensitivity, allowing you to adjust the thickness of your lines by tilting the pen, similar to a traditional pencil. This feature is ideal for shading and varied strokes in drawing applications.

Important: Magnetic attachment does NOT provide wireless charging for this model.

7. Troubleshooting

Stylus not responding after turning on: If the pen does not work after turning on, ensure no other stylus (like an Apple Pencil) is connected to your iPad. Go to Settings > Bluetooth > Apple Pencil > tap "i" > Forget this device. Then re-pair the KEEPRO Stylus Pen.
Shortcut functions not working: Ensure the stylus is successfully paired via Bluetooth to your iPad. Shortcut functions (one-click undo, quick screenshot, quick memo) require an active Bluetooth connection.
Inaccurate or lagging performance: Check if the stylus tip is securely attached. If the issue persists, try replacing the tip with one of the spares provided. Ensure your iPad's software is up to date.
Stylus not charging: Verify that the USB-C cable and power adapter are working correctly. Ensure the cable is fully inserted into the stylus's charging port.
Accidental marks from palm: The stylus features palm rejection. Ensure your iPad's software is updated, and the stylus is properly connected.
