This application allows you to add a QR code to your photos and videos in real time, containing the date, time, location, or any custom string you choose. You can customize the format, color, and size of the date, time, and location, as well as adjust their display position on the screen. Additionally, you can set the error correction level of the QR code and include a specific string, such as a URL.

To zoom in and out, use your fingers to pinch or adjust the slider to change the zoom ratio. By default, the text will automatically orient itself according to gravity, but you can manually set the orientation on the settings page (accessible via the icon at the top center). You can also configure the camera resolution from the settings page (VGA / HD / Full HD / 4K). The user interface is designed to be simple and user-friendly, featuring intuitive icons for easy navigation.

If you want to customize the text in your QR code, such as adding your website URL, please click the button in the upper right corner to enter the URL. Otherwise, the default QR code text will display the current date and location.

P.S. This application is also capable of reading QR codes.
