Hey Asa,
Most people don't seem to want an app for this; they want a native version. Our app which provides this functionality (see above) is doing okay, but most of the workarounds/hacks that you'll need to do involve requiring a store account, or using the API in very unconventional ways, that may not jive with other apps, which people are understandably hesitant about. You may not see that much interest.
