compass go is an iPhone application that shows the direction and distance to a point of interest. it can also be used as a GPS compass, a sun compass and a general navigation utility as it also has a built in magnetic declination indicator.

when you are at a place which you want to find back later, just tap ‘Set Target’, ‘Use current location’ and you are set! later on when you are trying to find your way back, just start compass go and you will see the direction and distance to your target.

it is very useful in situations where a map doesn’t work well, like on a huge parking lot, in the forest or a holiday resort where the map is not accurate. Find that bar on the street with no name, find that place on the beach where the hot babe is, etc.

the application continuously reads your position and updates the screen. If the compass is set to ‘ON’, the compass rotates and assumes that you point top of the iPhone in your current heading.

you may also enter a GPS coordinate which is very useful when you are doing stuff like geocaching or using coordinates from a map.

when you get closer to the target, the background changes from blue to orange to green. green means less than 20m/22yd to target, orange means less than 100m/110yd or within the current (±) accuracy limit. if you are exactly at the target (<2m/yd), the direction arrow disappears.

when using the live compass mode, make sure you walk in a straight line to get as accurate readings as possible.

if you don’t have a GPS iPhone, your direction may be very wrong at times. use the built in sun compass to confirm your direction. generally it works quite well when there is good cell-phone coverage. You have to move more than the (±) accuracy limit to get a new reading.

you may also use this application together with an ordinary compass to achieve a very exact target hunting device. the application also has a built in magnetic declination indicator (red/white arrow) which compensates for the local declination wherever you are.

if you want to see driving directions on a map, just tap ‘Show map’ and it opens up the map application.
