Last updated on July 31st, 2020 at 05:48 pmThe built-in Compass app is a great orientation tool provided by your iPhone. In iOS 7 it’s available, by default, on your first home screen in the bottom left corner.
You need to calibrate the Compass whenever you open the app. Calibration is accomplished by tilting the screen, which triggers the roll of a red ball, within a circle. Calibration is complete when a full circle is drawn.
Update: iPhone Compass calibration is done automatically as long as the proper iOS settings are used.
If you’re a newbie to the Compass app, or simply never spent enough time to learn how to properly calibrate it, here is how to do it. It’s an easy but very efficient trick that helps you to perform iPhone Compass calibration within a second!
360° Compass Calibration Move
Simply open the app and perform a single circular motion with the hand that holds the iPhone. If you’re right-handed you need to rotate your wrist 360° degrees from left to right. In the same time, use your fingers to tilt the device. Perform a backward-tilt in the first half of your wrist rotation and change towards an upward move during the final 180° degrees of your wrist rotation.
This might sound complicated, but I assure you that it looks very easy. Simply watch the video available below and you can see how to execute the motion and calibrate your iPhone’s Compass within one second.
Level Meter and InclinometerHere is another great tip for discovering all features of your iPhone’s built-in Compass app. After calibrating the Compass you can swipe left to activate a Level Meter. You can check any surface and see if it’s level, or how much adjustment there’s needed, to make it perfectly level.
You want more? Place your iPhone on its edge and you’ll transform it in an Inclinometer. You will be able to tell the inclination of a certain surface. You don’t have to be a constructor to use this feature. You can easily establish the incline of a ski slope, for example.
