Good, but can act up

Bought the app to use to locate isolated wilderness research sites with known UTM coordinates.

Pros: Easy to add waypoints, name them, and make groupings. Works in multiple coordinate systems. Will cache sat images for use when youre out of data range (but it works MUCH better if you are 3G connected). Continuously displays compass bearing.

Cons: Order of waypoints changes randomly if you swap out of the app to another app and then come back, or if the app crashes. Waypoints need to be entered in reverse order; last waypoint added to the list is the first waypoint youll be directed to. Far to easy to accidentally add a waypoint twice. Data displayed changes by itself; often just when you need it the most, distance to the waypoint will no longer display. App & phone sleeps when not used, so if youre watching the screen as you try to follow a bearing to a waypoint, you need to keep interacting with the app to keep it awake. Can take 20-30 seconds after waking to find you again, even if the phone only went to sleep for a moment (a good way to freeze your fingers in the winter). New waypoints default to your current location coordinates, which has to be erased to add new coordinates.

All in all, very useful, but would be so much better if the cons were fixed.
