About this app

ARCore Ruler app - Powerful tape measure tool, which takes advantages of the use of Augmented Reality.
Please note that AR Ruler app works only on ARCore-supported devices. Check device compatibility: https://developers.google.com/ar/discover/

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) Path - allows to calculate the length of the path.
7) 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.

Ruler app is ALSO AVAILABLE FOR IPHONE:

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. If you see that mm ruler app scale is visually stretched/ shrunken, you can reset mm ruler app calibration manually. On-screen mm ruler app can be calibrated using different Base Items, including Debit/credit card or coin. Choose between Imperial (inches) and Metric mm ruler (centimeters).

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.

Ratings and reviews

Edited to add because clearly the developer didnt read my review: I know how to cancel the subscription, and did so a few months ago. I couldn't figure out how to use this ruler. I sent an email to cancel my payments and even canceled in the subscriptions area on Google Play. The payments aren't being taken out of my account and I'm not finding the app on my subscription page, however; I'm being sent emails twice a month for the last three months telling me my payment has failed to go through.

Simple functional ruler with easily adjustable units. Easy to use. Don't use it often, but went to use it today and found that you have made it almost unusable with the ads that you have implemented. Not happy. Looking for another option. $20 per YEAR is ridiculous. Pretty ridiculous for even a one time purchase. You can't be serious.

Never worked 😕Last 2 features needed additional downloads - but those were not compatible with my phone. Ok, tried the reference one instead. Took a picture of my cutting board to test it. I put the long side of my debit card alongside it. I adjusted the length of the card, checked the checkmark ✔️to measure, or at least go to the next step, but it did nothing. Tried it again, and nothing again.
