Curiosity got the better of me...
So I thought I'd try it... (Android flavour).
Default shows 10 miles range, yet I'm seeing messages from 125000 miles (yes, I know, that sounds a bit wrong on a planet that's only 25000 miles round). Tried moving the range down to two miles, and it force closed on me...
Tried it again, same result.
I've only seen two or three FCs this year, and this app has doubled it!
Uninstalled. Possibly a record for shortest existence on my phone.
No wonder he just puts the apk up on his site, if he put that kind of buggy code up on the market where there is feedback he would be flamed until he was charcoal.
