According to their site, if you have an iPod Touch/iPhone or iPhone 4 iOS 4.0 or higher, they do have a free app you can download, and you can purchase it off of iTunes.

Apparently they also have an app for iPad & iPad2 in iTunes as well. I'm not sure if this one would cost anything.

If you don't have any of those versions, then unfortunately, you can only use a desktop computer or a laptop. I just tried searching for it on my iPad Air, and I can't find it.
