The iPhone compass and level are two separate tools: the Compass app provides basic navigation, while the level feature moved from the Compass app to the Measure app in iOS 12 and later. To find the level, open the Measure app (located in your Utilities folder) and tap "Level" at the bottom of the screen.
Where to find the iPhone compass and level
The Compass app is pre-installed on your iPhone and remains in its original location. The level feature, however, was relocated with iOS 12. It is no longer in the Compass app. To access it, open the Measure app and tap the "Level" option at the bottom of the screen. The Measure app is found in the Utilities folder on your home screen. You can choose from different themes and color schemes to personalize the app's appearance. The app may also include other useful tools such as a flashlight, magnifying glass, or QR code scanner. Some versions of the Compass and Level app include a flashlight function for working in low light conditions.
How to use the Compass app on iPhone
The Compass app uses the built-in magnetometer of your smartphone to provide an accurate compass reading. To get an accurate bearing, hold your iPhone flat to align the crosshairs at the center of the compass. The app displays the direction your iPhone is pointing, your current location as coordinates, and your elevation. For the Compass app to show your location and elevation, you must enable Location Services. Go to Settings > Privacy & Security > Location Services, tap Compass, and select "While Using the App." You can lock your current direction by tapping the compass dial; a red band will appear if you go off course. Tapping the coordinates displayed in the Compass app will open your current location in Apple Maps. Be aware that magnetic or environmental interference, including magnets in iPhone earbuds, can affect compass accuracy. The digital compass is intended for basic navigation assistance only and should not be relied upon for precise location, proximity, distance, or direction. If you need to adjust your phone's orientation for navigation, you can also fine-tune your maps and navigation app settings to improve your experience.
How to use the level in the Measure app
Once you are in the Measure app and have selected Level, you can check both horizontal and vertical surfaces. The level function utilizes the accelerometer sensors in your phone to determine the levelness of a surface.
Horizontal leveling
- Place your iPhone flat on its back on the surface you want to check.
- The screen will show two bubbles.
- When the surface is perfectly level at 0 degrees, the screen turns green and you receive haptic feedback.
Vertical leveling
- Turn your iPhone on its side and hold it against the object you want to check.
- The screen will display an angle.
- When the object is straight at 0 or 90 degrees (depending on orientation), the screen turns green and provides haptic feedback.
The measurements provided by the iPhone's level are approximate. For a truly precise reading, a dedicated spirit level is recommended. You can save your measurements for future reference, compare different measurements, or share them.
Tips for accurate compass and level readings
To calibrate the compass, you can make a figure-eight motion with your phone to improve its accuracy. Keep your iPhone away from magnetic objects, including the magnets found in iPhone earbuds, as these can interfere with readings. Ensure Location Services is set to "While Using the App" for the Compass app to show your location and elevation. You can adjust the sensitivity and accuracy of both the compass and level functions to suit your preferences. Lock the screen orientation to ensure a stable reading and prevent accidental screen rotation. Remember that all level measurements from the Measure app are approximate.
Frequently Asked Questions
Why did the level disappear from my Compass app?
The level feature was moved from the Compass app to the Measure app starting with iOS 12. Apple made this change to consolidate measurement tools in the Measure app.
Can I use the iPhone compass without cell service?
Yes. The Compass app uses your iPhone's built-in magnetometer and does not require a cellular or Wi-Fi connection to show direction. However, to display your current location coordinates and elevation, Location Services must be enabled, which uses GPS and does not rely on cell service.
How accurate is the iPhone level?
The iPhone level provides approximate measurements and is suitable for casual tasks like hanging picture frames or checking shelves. For professional-grade precision, a dedicated spirit level is more reliable. The level uses the device's accelerometer, and the screen turns green with haptic feedback at 0 or 90 degrees.
