I just did a full blown reset to fix my Samsung as apposed to replacing it, as I anticipate in a few months of jumping over to Verizon...I can understand why Google My Tracks is unsupported and has disappeared; but just discovered Backpacker Pro - which had issues has gone too.

I see Guthook's got a PCT and other apps out there and they are well rated. i am looking at Geotracker as a well rounded replacement...

What do you like and why?
