I'm curious if you've given any thought to publishing your App to the Amazon App Store, in addition to Google Play? I ask specifically because BlackBerry 10 devices currently support an Android emulation mode but they can only [easily] load APKs from the Amazon store. I fully appreciate that making a native BlackBerry 10 app is likely very low (or more likely not at all) on your to do list, so this would offer a relatively painless way for BlackBerry users to take advantage of your service.
