Last I checked android dev tools have a broad support for emulating speeds of various devices, so I don't think this is an issue really, and depending on what the app does it might not be that demanding, doubt its 3d or such?
So it could be made to a minimum spec easily enough, fact is though that apple/ios is more hyped/cool/whatever word is used now a days, in the general public's eye currently.
This is not meant to be a kick at apple, I don't have a preference for either, I chose what suits me best, and I think others should chose what suits them best, and since we all are different it means different things.
That said I would really love to see people begin using the tools that offer easy compiling of both versions more, as long as no proprietary components/functions are used, which all things considering I don't think this app would make use off. Heard those compilers work quite well even for optimizing.
