I've been playing around with some android coding and finally release an app that plots the planets aound you.
It calculates the direction + altitude from ephemerides and uses the compass api to plot the positions relative to the user... as 100 other apps out there.
I've only been able to test it at my home location (stockholm) so would be happy to here if it works / show resonably correct results.

(works for android > 2.2)

best regards,
