AR Ruler is now AR Room Planner

Same app. Same team. The toolbox just got a lot bigger.

Most publishers ship a shelf of single-purpose apps — one for floor plans, another for AR measuring, another for a ruler, another for a level. We took the opposite bet and put every measuring tool in one app, and we keep building more. That has been the idea since day one, back in 2017 — hence the name: Measure Tools.

Measurements are not perfect, but for estimating the cost of flooring change it is great. Probably will get better with newer phones.

How our measurement tools work

ā†

Vertical / Height Measurements

  • Point at flat surface (floor / ground / table),
  • Tap & start the measurement
  • A vertical guide appears,
  • Raise the phone towards the top,
  • Tap again to finish the measurement.
  • Starting on a vertical surface (wall), using this mode, you will get a segment parallel with the floor. It uses the starting surface as a reference.
Vertical / Height Measurements

Horizontal / Floor Measurements

  • Point at flat surface (floor / ground / table),
  • Tap & start the measurement
  • A horizontal guide appears, on the selected surface,
  • Move the phone pointing towards the end of your target,
  • Tap again to finish.
  • Using this mode you can measure even if there are objects (furniture) in the way. You only need a clear view initially, when scanning and starting the measurement.
  • Using this mode on a vertical surface (wall), you will measure distances only on that wall. Be mindful of the surface you start your measurement on.
Horizontal / Floor Measurements

3D Box Preview

  • Point at flat surface (floor / ground / table).
  • First tap places the origin of the box.
  • Second tap forms the base of the box.
  • Raise the phone for the box height.
  • Tap a 3rd time to finish.
  • Use this tool to quickly see the size of an object or space.
  • Works on horizontal surfaces, but also vertical (walls).
  • Use this tool to preview how furniture will look in your room & how much space it will take.
3D Box Preview

Show Angles

  • Show angles between two adjacent segments.
  • Just turn this on and take measurements.
  • This mode can be used regardless if you use free, horizontal or vertical measurements.
  • Requires Chain Measurements to also be active.
Show Angles

Chain Measurements

  • Turn this mode on to link each segment with the previous one.
  • Finish by tapping the green checkmark.
  • This mode can be used regardless if you use free, horizontal or vertical measurements.
  • Use this phone to quickly measure an area.
  • It also automatically calculates the area and perimeter you are measuring.
Chain Measurements

Floor Plan

  • Start by scanning the floor
  • Tap each corner of the room to mark the floor shape
  • Set the wall heights
  • Add windows and doors with two taps on a wall
  • Save your plan as a project you can view in 2D or 3D

Want Reliable Measurements? What Most People Miss

ā€” Not getting the right measurements when using an ar ruler app? Ditching that old tape measure for one that is on your phone, you always have it with you, does not take up any space, it stores measurements with pictures - that is an easy decision, right? But, are the phone measurements reliable? How is the accuracy? People say these camera measurement apps don't work well, they are not accurate. You probably heard this or thought this too.

Well, here are the secrets to taking the best measurements with a camera ruler app possible. Knowing these details you will understand how the camera sees your environment and how you can best use it to measure objects and spaces around you. Here are our 5 tips for camera measurement apps that will make you measure accurately every time:

Want the full breakdown of why AR measurements drift and how to fix each cause? Read the full accuracy guide.

ā†

Good Lighting

  • Make sure there is enough light in the room.
  • The app does not work in darkness or low light conditions.
  • Avoid reflective / glossy surfaces.
  • Changing lighting conditions during measurements should be avoided.

Move Around Slowly

  • Scanning surfaces is required before taking measurements.
  • No device movement means no scanning, so measurements are not possible.
  • Move the phone really fast and scanning might fail.
  • Move naturally left - right, up - down until you see yellow dots.
  • Yellow points mean information the app understands. The more, the better.

Get Close

  • Move closer to the object or area you want to measure.
  • Avoid standing too far when scanning details.
  • Ideal distance to start a measurement is 30 cm - 1 m (1 - 3.3 ft)
  • Phones with a Lidar sensor can accurately start a measurement from up to 5 m (16 ft) away
  • If you are using the proper measurement mode, you only need to keep this in mind for the start of the measurement. Ending the segment can be much further away without problems.

Double Check

  • Once you took a measurement, take a few steps to the side.
  • If the segment remained aligned with what you have measured, your measurement is fine and you can use the value.
  • If the segment floated away, it means the app did not understand the environment properly and you should retake the measurement.
  • Keep in mind all the other tips to retake the measurement.

Distinct patterns

  • Single color, textureless surfaces are harder to scan.
  • Look for distinct patterns and details for better tracking.
  • Avoid reflective surfaces, like mirrors, glass or some tile.
  • Phones with a Lidar sensor will work on some of these surfaces as well.
