Great work! Im using the lastest version of the app with a Galaxy S4 (Android 4.4.2)
There seem to be a problem with the timestamps. At 14:12 it gives me 02:12. It seems to default to an AM/PM mode, but withouth the AM/PM label? An optional 24h mode would be preferable.
It seems i'm not able to edit the borders of a search area once it's finalized. This functionality should be looked in to.
For future development i would recommend implementing customizable categories for the finds. And the posibillity to hide/show specific categories of items on the map, as well as in the find list.
