10 Best Angle Measurement apps for Android and iOS (Angle Finder Apps)

Looking for an angle measurement app that is more accurate, Read on.

Best Angle Measurement app for android

You need to measure an angle urgently, but you can’t find your protractor? No worries. If you have an Android phone or iPhone, angle measurement can be done quickly without a protractor.

With the availability of an angle measure app or angle finder app, you can utilize augmented reality (AR) to measure lines and angles using only your Android or iPhone’s back camera. If you’re in a pinch and don’t have access to a protractor, this angle Measure apps comes in handy.

Angle measurement app or Angle finding apps are tools for measuring angle and inclination. It uses the arctangent of gravity between two axes to get accurate findings dependent on sensor quality.

This angle finding app is very accurate and can be used in Physics lab, woodworking, surveying, drafting and even in complex industrial work.

Without further ado, here is the list of the 10 Best Angle Measurement apps in 2021.
