Unfortunately in it's current incarnation CANDDi capture doesn't render well on mobile devices (it takes up a very large amount of the display space and obscures the rest of the site).
Hence by default CANDDi Capture is turned off for mobile devices. If you wish this to be enabled then please send a request to firstname.lastname@example.org.
CANDDi Capture will trigger on tablets and larger screen.
We have a feature request to improve the design on mobiles.
