I suppose this might be the appropriate place to mention the on-going development of my own application:
https://bitbucket.org/StrawMan/airsafecast-publicIt's written in AIR/AS3, targeted at Android (I suppose one could port it to iOS, given that AIR is also available on that platform).
I have a couple debug builds up and the source code sits in a Mercurial repository.
Would love to be able to tie it into the Onyx, unfortunately that hardware is a little beyond the scope of my present budget, but I'm keeping a close eye on it.
In any event, if anyone wants to fork around with the source and send me patches/improvements, feel free!
Cheers,
- Jay
