Maybe you should add a QR code or MS-TAG to your site that way, anyone that has a phone can just scan the app and take them to the marketplace to download. Your app is great! Thanks for making it free!!!
Just my 2cents but I think that with Technology today, the QR/MS Tags are becoming more and more usable!
