Ubuntu Touch app

[pparent76]

Hi,

Thank you very much for your code!

I just want to mention that I've made an app for Ubuntu Touch, based on your code that I've modified just a bit.

Thank you for making that possible, by publishing your code as Free Software!

You me reuse some of the improvements I made if you want
