It does seem to run on the iPhone 3gs, albeit it slowly. One suggestion I might make is to detect iPhone/Android devices, and offer a popup control.

Further, you can provide the right meta data so that it can be added as a web-application, right to the iPhone home screen.

Hi. These are great suggestions! A mobile optimized version of the engine and services are very high on our to do list so you can expect to see something in the near term.
