BYOGUIDES is considering an interactive PDF edition of the Coral Finder. If this appeals to you write to us and say so!  Please don’t ask for a phone app - the Coral Finder works because Look-Alike pages present a small number of visual ‘best bets’ together on the same page allowing our visual supercomputer (eyes) to do the comparative pattern recognition work that interpreting text denies us. Likewise, reducing the Coral Finder to flicking through a stamp collection of single images on a phone screen gets in the road of ID / learning. However, we do believe that the Coral Finder can work well as an interactive PDF on a late model tablet (e..g. iPad Pro - big screen, powerful processor and pinch-to-zoom) or a desktop computer.
