I just use aprsdroid to broadcast where I am, mainly so the XYL can keep tabs on me, hi. Not as cool as using a vhf radio to do that of course, and it's a bit funny to use the mobile phone network for what ham radio has done for a few decades.
Also my son uses it, he's a ff/emt/water rescue tech and it's very interesting to see what he gets up to in a 12h shift.
