I'm not affiliated with
www.winnigas.com at all, but it was easy to whip together this app that invokes the website directly.
If this works, let me know and I'll try to get in touch with the owner of winnigas and see if he like it.
Since this is not on the google play store (yet), you need to set your phone to allow external content to be installed.
