Works well, easy to use
Seems to work well, and is easy to us and learn. I like the actual satellite maps it uses for location. Also I like you can use the built-in compass to orient the display. Just be sure to calibrate your iPhone compass before using.
I tried it while it was in the background and when the phone was "locked" but still on. The audible alarm went off as it was supposed to. I really like the app. Just make sure your phone is plugged in as the GPS location chip uses a lot of phone power.
