You can bookmark the Companion App in your mobile device's (smartphone or tablet) browser so you won’t have to scan the QR code each time you want to use the companion app. The Companion App will appear in the next available space on your phone's Home Screen. If you are not familiar with how to bookmark a URL on your mobile device, please refer to your device's instructions to do so.
The Companion App is a webpage and not a standard downloadable app. This is so there is as little lag as possible and when you change lanes or deploy a power-up, it is seen in game real time.
