QRControl is an unofficial app designed for iPhone users who want to control their GoPro cameras using custom QR Codes. This app is especially useful for those without reliable internet connections, as it simplifies the process of controlling their cameras on a mobile device.

With QRControl, users can generate QR Codes that support a wide range of functionalities for various GoPro camera models. These functionalities include setting video, photo, and time-lapse camera modes on the HERO12, HERO11/Mini, HERO10/Bones, HERO9, HERO8, HERO7, and MAX cameras. Additionally, users can set up custom Protune configurations, adjust camera preferences, and trigger time delay starts, including sunset and sunrise.

QRControl also supports motion detection video captures and GPS speed-triggered captures. Users can save multiple QR Codes for different camera settings and easily share them with others.

Please note that QRControl is an unofficial app developed by David Newman and is available for free on the iPhone platform.
