Learn how to use the iPhone Measure app to check if a surface is level. The app includes a built-in level tool that helps you determine if an object or surface is flat or at an angle. I’ll show you the steps to use this feature correctly.

If you need to check if a shelf, picture frame, or table is level, the iPhone Measure app makes it easy. The level tool uses your iPhone’s sensors to give you accurate readings. Learn how to read the angle measurements and adjust surfaces for a perfect balance.

How to Access the Level Tool

1. Open the Measure app – Look for the ruler icon on your home screen and tap it.
2. Switch to Level mode – At the bottom of the screen, tap Level (it looks like a small spirit level).

How to Use the Level Tool

1. Place your iPhone on the surface – Lay it flat on the table, shelf, or object you want to check.
2. Check the screen – The app will show:

• 0° (green screen) = The surface is perfectly level.
• A number (red screen) = The surface is tilted (the number shows the angle).

1. Adjust the surface – Move the object until the screen turns green and reads 0°.

How to Calibrate the Level for Better Accuracy

If the level seems off, you can recalibrate it:

1. Place your iPhone on a flat, known-level surface (like a table you’ve already checked).
2. Tap the screen once – This resets the level to zero.
3. Test again – Now, the readings should be more accurate.

Tips for Best Results

• Clean your iPhone – Dirt or a case might affect the sensors.
• Hold it steady – Movement can make the reading fluctuate.
• Use a flat edge – For small objects, place your iPhone along the straightest part.
• Check multiple spots – Some surfaces may be uneven in different areas.

When to Use the iPhone Level Tool

• Hanging pictures or shelves – Make sure they’re straight before nailing them in.
• Setting up furniture – Check if table legs or cabinets are balanced.
• DIY projects – Use it for woodworking, tiling, or any task needing a level surface.

Final Thoughts

The iPhone Measure app’s level tool is a handy feature for quick checks. While it may not replace a professional level for precision work, it’s great for everyday tasks. Give it a try next time you need to straighten something!
