I have the gps coordinates where my Spark probably went down from the flight log. I'm looking for an android app that will lead me to that point. So far all I can do is write those coordinates down then try to locate from my own coordinates which is awkward. None of the apps I've found so far seem to let you enter the coordinates you're looking for, rather than an address. I'm sure such an app would be in great demand by bank robbers, drug dealers and such who bury their loot in the desert.
