# Testing the app

Testing your app is a crucial step in ensuring its functionality. Here is the simplest way to test your app. Ensure that your laptop and tablet/mobile devices are connected to the same Wi-Fi network.

Follow these steps to test the app:

1. Click on <mark style="color:green;">**`Connect`**</mark> and select <mark style="color:green;">**`AI Companion`**</mark>. This action generates a QR code.

3. Point your camera at the QR code and hold it until the scanning process is complete.
4. Your app should load on your mobile device, and it should now be operational.

This method provides a quick and efficient way to test your app on a physical device, allowing you to experience its functionality as intended.
