WSPR on an Android or iOS tablet?

A version of WSPR that would run on my iPod Touch 4g or even a version that would run on an Android platform would be a very desirable app. Although there is at least one app for WSPR, this is just a way of looking at the on-line database and not a version of the actual WSPR beaconing software.

I asked this before (back in March), but does anyone know if such a WSPR beaconing app is likely soon, if ever?  Not being a software guru, I've no idea how difficult this would be, but can see a lot of demand for such an app.
