Unfortunately the site looks a bit of a mess on iOS. I suggest a basic browser detect so you can display a nicer looking splash page to mobile users.

You named your product Steve. If you want to go the Jenkins/Ask.com route of having a product with a human name then come up with a memorable and attractive avatar for Steve ASAP. Personally I would be weirded out using a product with a bland and generic name like "Steve". I understand this is subjective, but you may want to iterate on the name until you find something interesting and memorable. This may sound trite, but in a crowded marketplace where every conversion matters you'll want every edge you can get.
