I've not had good luck with the android app but the compass works well. I've used it for all the fox hunts I've participated in.
I'm doing a presentation on it for the November "Show & Tell". Be there or be square!
I think the Android app works best with continuous carriers, not intermittent signals like repeaters or foxes.
Andrew and I were the only KSDR owners I was aware of so adding you makes three!
