I too want to have an official Android app. However, I can think of many reasons why the developer hast done that already.
If you ask for a Android App, you actually asks the developer to write multiple applications for each device. As an Android developer you have to take care of so many different devices, it is so much time consuming to take care of everyone in this market. While the app. can work on device from HTC it may or may not work on e.g. Motorola.
I think that is exactly why there is an Apple application rather than Android.
I think if you guys really insist in a android application, consider that the developer needs more donations for a) android developers and b) differed android phones.
