I am so excited for this for my Android smartphone! Will we buy it from our respective OS's normal store, or is there a place where we can buy it directly from you so you maybe get a bit more money from it?
For Windows Phone, I know that Microsoft charges much higher development costs than Apple or Google do. I listen to the This Week In Blackness podcast and they really wanted to make a Windows app but it was so much more money than the more popular platforms that they had to decide against it.
Edited to add: Bought it on Google Play, love it! The control is surprisingly intuitive.
