I actually don't do it on my phone, because, well, it's very small and crappy.

I do use my iPad a lot. I think I somehow created an icon like app that opens up Penny Can. I would imagine I could do the same for my iPhone? Maybe this is an Apple platform thing?

Let me try to recall how I did that.

Edit add: I must have done this... http://ipadinsight.com/ipad-basics/how-to-add-a-website-to-your-ipad-home-screen/

Or something similar, because I have a number of icons on my screens I don't necessarily need, but somehow I have them.
