Argot (pronounced 'are-go) is an Android application that allows you to bookmark locations using GPS. The bookmarks can then be organized and used for small-scale navigation (e.g. finding your car in a parking lot, or marking a meetup location in an unfamiliar neighborhood).
The bookmark list
The bookmark list can be sorted by either the bookmark name, the bookmark's proximity to your current location, or the date and time that the bookmark was created. Measurements can be displayed in either metric or English units.
The navigation screen displays the direction and distance of the bookmarked location, along with the accuracy of the GPS signal of both the bookmark (when it was saved) and your current location.
