Both the android and iOS versions of BombSquad remote are open-source and can now be found on github:

github.com/efroemling/bombsquad-remote-android
github.com/efroemling/bombsquad-remote-ios

They are both terribly sloppy codebases but they get the job done.
If you'd like to make any improvements, contact me at eric@froemling.net for github push access.
Cheers,
