Field Flags is a GPS application designed to help farmers keep track of rocks, broken tile, logs, waterways and other hazards in their fields. Instead of marking a large rock with a little orange flag and hoping to find it again, the user can drop a pin on the Field Flags map with the click of a button and then later on the Field Flags map will lead the user back to the exact spot within a few feet. Pins can be named and classified by the user, as well as edited and deleted. Multiple users on different phones can share the same set of pins. Field Flags is meant to save farmers time and reduce soil compaction due to searching for previously marked hazards in their fields.
