Measuring Angles: Angle Meter

What We Like
  • Several tools in one app.

  • Accurate measurements.

What We Don't Like

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.

What We Like
  • Distance and height measurement app in one.

  • Accurate measurements.

  • Easy to use.

What We Don't Like
  • Full page and banner ads.

  • Banner ads during measurements.

  • Requires good lighting to work right.

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.

  • Uses Google Maps distance feature.

  • Highly detailed maps.

What We Don't Like
  • Almost identical to Google Maps.

  • Banner ads at the bottom of app.

  • Limited features.

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.

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.

What We Like
  • Includes both ruler and protractor.

  • Place object on the screen to measure.

  • Measure objects captured in photos.

What We Don't Like
  • Not intuitive to use.

This ruler app from endoscope works slightly differently than others. Instead of measuring objects alongside your phone, you can place objects directly on the screen and slide the measurement points to the edge of the object. You can save measurements if you need to reference them later.

The app also lets you take a picture with your camera, then use the app to measure the object in the photo.
