Canviz App Installation
First install TestFlight (an iOS app from Apple) which will allow you to use the Canviz App before it is released on iTunes. Here is a link to TestFlight.
Once you’ve installed TestFlight on your iPhone, enter your iTunes account email address below (the email address you use to download apps from iTunes to your iPhone, this will identify your phone). You will then be authorized to install the Canviz app (it may take as long as 24 hours to register), and an option to install the app will appear in TestFlight.
