App Features

• Full 360° Angle Finder
  Measure any angle—vertical, horizontal, or anywhere in between. The app makes it easy to check precisely how far you’re off, all around.

• Versatile Bubble & Spirit Levels
  Forget guessing if something’s truly level. The spirit and bubble levels are spot-on, showing when you’re at key angles like 0°, 90°, 180°, and 270°.

• Surface & Plummet Tools
  Need to level surfaces or check vertical alignment? The plummet tool and surface level display angles in real time and can even warn you with sound when you’re close to your target.

• Store and Recall Angles
  Have a few target angles you use a lot? Save them and recall with a tap, perfect for ongoing projects or repetitive checks.

• 6-Point Calibration Assistant
  Want precision? The calibration system helps fine-tune the app down to 0.1°. You can calibrate protractor and surface level functions independently for even better results.

• Manual Target Angle Input
  Already know the angle you need? Just enter it, and the app tracks how close you get while making adjustments.

• Built-in Flashlight and Ruler
  Working in a dim corner or need to size things up? Fire up the flashlight and use the on-screen ruler for extra convenience.
