We strongly believe that the future is in the open web standards (i.e. web apps and HTML5) and not in the proprietary apps for closed systems like iPhone, etc.. We would much rather focus on creating the best possible experience for our players right in their web browser, instead of supporting and maintaining custom apps for the multitude of various smartphones and PDAs out there.
We do however provide a mobile version
of GameKnot over at m.gameknot.com
for handheld devices with small screens. It's a smaller and lighter version of our website however, so it doesn't have all the features present on our main website.
