Description

Modern technologies (Augmented Reality) and classic approach (on-screen ruler) are combined in the single measurement app.

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.

Novel, Accurate, Easy, Free w/adds, and not broken

Waisted so much time with promises of ruler apps for 6 plus (no built in AR). They are either broken, totally inaccurate, ad crazed, limited to 21” tape or less (come on, I can eye ball 21”s, who needs an app for that. Finally a free tape measure app that actually works, super accurate, and so intuitive. Several methods for measuring in this app.

I was so impressed, just had to take time to do a review. Also love the auto-magnification when you are setting the object’s end points - great idea.

Only weird thing is, when the app downloads, it called PrimeRuler - so not sure it’s exactly the same as the advertised and previously review app show here, but similar.

Finish your app

THEN upload it.,Like so many others, the steps that I have to go through to log in are first: open the app and look at a green logo screen for about 60 seconds before it crashes once. Then second: open the app a second time an log in again, even though I have used the app within the last 10 minutes and am definitely already logged in. Really, this app is constantly updated with 'new features.' Why can't you fix the absolute MOST BASIC FEATURE: LOGGING IN? Please finish developing your app, then

Does its job

Dont understand why the other popular ruler app has so many more downloads while making you pay money to measure in inches. This one isn't fancy and it has some ads, but it lets you do pretty much anything you would want to (in inches!) for free. Also has a nice slider system to accurately measure a small object that you place on the screen. Its a winner for me
