The 10 Best Measurement Apps for Android in 2021

Measuring Angles: Angle Meter

Angle Meter is a useful app for measuring the angle of real world surfaces. You can hold the phone standing up on any surface and the display will show you the angle of that surface relative to the ground.

The app includes several other tools, including a protractor that lets you place your phone flat to measure surface angles, and a laser level tool that lets you place your phone on any object above the floor to view how level the surface is.

There's also an icon in the upper left corner of the screen that acts as a compass and always shows you the orientation of your phone relative to due North.

Build 3D Floor Plans: ARPlan 3D

ARPlan 3D is one of the more innovative measurement apps for Android on this list. It provides you with an augmented reality measurement tool for measuring the dimensions of a room.

First, measure the height of the wall, then measure the perimeter of the floor. The app will convert those measurements into a full 3D model of the room which you can save as a PDF, JPG, or DXF file.

Simple Level Tool: Bubble Level

Bubble level is one of the simplest apps of all. It works like a regular bubble level you'd buy at the hardware store, but it's three bubble levels in one. The bottom of the screen shows the x and y coordinates if the level is at all off-center.

Levels and Angles: Ruler - Bubble Level & Angle Meter

This is a slightly more advanced bubble level app that includes four features in one app, including an on-screen ruler, a 2D rule for measuring two sides along the phone at once, a bubble level, and an angle measurement utility that uses the camera to measure angles of objects in the real world.

Measure Distance: Smart Distance Meter

Smart Distance Meter, as the name implies, helps you measure both the distance to a target, and the height of the target itself, using just the phone camera.

You'll need to calibrate the height measurement by manually entering the height of the phone above the ground, but once you do, placing the crosshairs on the target returns a fairly accurate measurement of height and distance to target.

Map Measurements: GPS Fields Area Measure

If you'd like to measure longer distances, this is the perfect app for the job. It incorporates the Google Maps distance feature into advanced features that let you measure both distances and areas on top of the Google map of an area.

Simply tap the distance, area, or point of interest mode, then tap the map to measure out distances between taps. It essentially makes the Google Maps distance feature easier to use, with additional measurements possible.

Measure Objects: Measure

Google also has its hands in the augmented reality measurement game with its Measure app. This is the perfect app to use if there's an object you want to measure and all you have available is your phone.

Just view the object with your camera and tap the starting point to begin measuring. As you tap each point on the object, Measure will show the dimensions of each line.

Simple Ruler: RulerApp

If you're looking for a very quick way to measure small objects, just launch RulerApp, lay your phone next to the object, and use your finger to mark the endpoints of the object. This app is very simple and easy to use.

Two Scale Ruler: Ruler

This simple ruler app lets you choose between inches or centimeters. Choose to measure from one side, two sides, or three sides of the phone. This app lets you quickly measure small objects in seconds.
