I've been develop chemical program with JAVA and put them on Pirika, but they will not work on iOS. I can write objective-C program. But it will not work on Android. I did not want to use the technology that can use only one OS.
Sequential batch Reaction Good example how to use Canvas.
Poseidon mini Polymer sequence simulation software.
DrawMol This program draw molecule on Canvas. If you are accustom to pirika molecule Drawing, you can use this program easily.get mouse position on Canvas and draw line, draw string, then you can easily build this program. This version worked on Safari, Chrome browser for Mac and not firefox. iOS version is not included. (2011.3.21)
Draw2FG This program count for functional groups number that in molecule. This version is not for aromatics nor Halogenated molecules. This version worked on Safari, Chrome browser for Mac and not firefox. iOS version is not included. (2011.3.21)
Now, DrawTouch is working on iOS simulator. (2011.3.25) But my iPod touch is very old and does not run this program. I need to find out friend who have iphone 4.
I also made pseudo 3D molecular viewer program.（2011.4.7）
And modify it to Frequency Viewer.
I modify molecular view program and made Sphere viewer. Please try Hansen Sphere Viewer with HTML5 enable browser Chrome or Safari.（2011.4.8）
I can easily build iOS version of Sphere viewer. (2011.4.9)
