Recently we released version 2.01 of SMARTCyp, which is the first version to use ChemDoodle web components.
When we did this we also changed the sketcher on our web server start page. It used to be a JchemPaint sketcher applet. Since this is java it simply does not work on all mobile devices (and Ipads). Now we instead use the ChemDoodle sketcher, which loads much faster, and is compatible for all mobile devices as well.
