Which platforms are supported?

Chess Arsenal is for iOS only: iPhone and iPad. There are no plans to make an Android version.

How do I export to other chess programs?

Choose Export or E-mail from the menu to get a PGN file. See this blog post for detailed instructions on Export.

How is the export file arranged?

Your exported PGN will appear as a single game, with variations where there are multiple move choices. Every key move appears as a comment of “My Move” following that move.
