AR Ruler app - Powerful tape measure tool, which takes advantages of the use of Augmented Reality.

AR Ruler app uses augmented reality technology (AR) to tape measure the real world with your smartphone’s camera. Target aim on the detected plane and start to use ar tape measure tool:

1) Line - allows to tape measure linear sizes in cm, m, ft, yd, apply mm ruler or inch ruler.
2) Distance meter - allows to tape measure distance from device camera to a fixed point on the detected 3D plane.
3) Angle - allows to tape measure corners on 3D planes.
4) Area and Perimeter.
5) Volume – allows to tape measure size of 3D objects.
6) Height - allows to tape measure height relative to the recognized surface.

Photo Ruler app is designed to accurately tape measure the size of any object by either taking a picture of it or to measure it on the screen. Photo Ruler app allows you to measure things just as conveniently and precisely as with a traditional mm ruler or tape measure tool.

How to use Ruler app:

Photo Ruler app:

Firstly, please ensure that the object you wish to tape measure and the object of known length (Base Item) are in the same picture. There is a predefined list of Base Items in the ruler app settings, including Debit/credit card and Quarter. Select the one you have. Use the Base Item which is closest in size to the object you wish to tape measure using Ruler app.

Secondly, ensure that the Base Item and the object you wish to tape measure using Ruler app are in the same plane and the ruler app camera is (or was) parallel to them. This is necessary to avoid image distortions caused by the ruler app camera perspective.

Align the Blue arrows against the Base item and Green arrows against the object you want to tape measure. The length of the measured object is shown on the Ruler app screen.

Ordinary mm ruler app:

Use screen as a traditional mm ruler app. You can tape measure size of a small object by placing it on the device's screen and adjusting line limiters against the object.

Accuracy of mm ruler app:
Given that you have accurately aligned markers, you will receive a measure that is as precise as when using a traditional mm ruler app or tape measure tool.

Not gettin notifications

I’m not receiving notifications when I get messages through the application. I have gone into my phone settings turned on the notifications for the line app. I’ve also gone through the application and turned it on turned it off I’ve tried re-downloading the app multiple times and I’m still not getting notifications. I didn’t have any issues with it but I recently logged out of the app and log back in and now I’m not getting any notifications. I would be greatly appreciative I could get some help
