Online Compass
A free digital compass that uses your device sensors to show which way is north. Works on mobile phones and tablets.
Your device does not have orientation sensors. Enter a heading manually to see the compass direction:
How to Use a Compass
A compass is one of the most fundamental navigation tools. Whether digital or analog, understanding how to read a compass heading is an essential outdoor skill that can help you find your way when GPS fails or batteries die.
Understanding Compass Bearings
A compass measures direction in degrees from 0 to 359. North is 0 (or 360) degrees, East is 90, South is 180 and West is 270. The 16-point compass rose adds intercardinal (NE, SE, SW, NW) and secondary intercardinal directions for more precision.
Magnetic North vs True North
Digital compasses (and magnetic compasses) point to magnetic north, which differs from geographic (true) north. This difference is called magnetic declination and varies by location. In some areas the difference can be 15 degrees or more. For precise navigation, you need to adjust for your local declination.
Compass Navigation Basics
To navigate with a compass, take a bearing to your destination, then walk following that bearing. Check your compass frequently and pick a landmark in line with your bearing to walk toward. When you reach that landmark, take another bearing and pick a new target. This technique keeps you on course even in poor visibility.
Digital vs Analog Compasses
Digital compasses in smartphones use a magnetometer sensor. They are convenient but can be affected by nearby electronics, metal objects and magnetic fields. For wilderness navigation, always carry an analog compass as a backup — it needs no batteries and works in any conditions.
When GPS Fails
A compass combined with a topographic map is your most reliable navigation system in the backcountry. GPS devices can lose signal in deep canyons, dense forests and during storms. Knowing basic compass and map skills is a critical safety practice for any outdoor enthusiast.
