ON 3D-CameraMeasure

ON 3D-CameraMeasure is a powerful and advance remote measuring tool on android. It performs measurements in any direction and plane in 3D space. There are no constrains on the camera direction or position relative to the measured object. Unlike 2D-CameraMeasure, the reference object/measured object plane not necessary to be parallel to the camera plane. This make ON 3D more powerful and flexible to measure anything at anywhere. It can be used as or even replace ruler and measuring tape in many situation where the traditional measuring method is not enough or difficult to apply.ON 3D-CameraMeasure is extra useful especially if you want to measure 1) Large object where simple ruler and measuring tape are not enough or difficult to apply. For example, angle of roof, area of a swimming pool, diameter of a roundabout, dimension of a football field, height of a wall, dimension of a room, distance from one side to another, etc. 2) Objects that are difficult or impossible to access. For example, outer dimension of a building, windows on a high wall, screen size in a cinema, object mounted on ceiling, area of solar panel on a roof, etc.It lets you measure anything in the fastest and easiest way as long as there is any rectangular object as reference.ON 3D-CameraMeasure performs non-contact measurement by using the device's camera and any rectangular object with known size as reference. You can use the predefined common objects such as credit card, A3 paper and A4 paper which is included in the application, or use your own custom object as reference.Using ON-3D is very intuitive and easy, as the operational step below:Place the reference object on the same plane as measured object --> Capture picture with camera --> Calibrate --> Measure in different modesFor more details information about how to use the app, please refer User Guide in this app. KEY FEATURES:
★ Measurements Modes: Length, Angle, Area, Diameter
★ Measure objects in any direction or plane in 3D space without the restriction to hold camera parallel to the plane
★ Length value assigned to all the ruler lines in all modes
★ Camera snapshot, auto-focus and flash light
★ Show 3D grid in calibration
★ Customizable line width, point size, text size,
★ 3 predefined reference object(Credit card, A4 paper and A3 paper)
★ Show verticality and tilt angle of device when camera is on.
★ Keep Screen Awake
★ Add/Delete measurements
★ 6 Measurement Units: m, cm, mm, in, yd, ft

★ 10x Zoom ViewIt helps you align the points on object boundaries accurately.


★ Customizable Picture ResolutionIt detect all your camera supported picture size and lets you select your best picture resolution among them. Calibration and measuring will become easier.


★ Save MeasurementIt lets you save your current measurement in SD card.


★ Open MeasurementIt lets you open the previously saved measurements for review or continue edit.


★ Import Image from GalleryIt lets you work with any photo or images in the gallery.


★ Instant Share & Send Measurement SnapshotShare or send your current measurements with your friends via Email, Facebook, Bluetooth, Instagram, Whatsapp, Messanger, etc.ACCURACY:The accuracy of this apps is highly depends on how well the user move the points to aligned with object boundaries when doing calibration or measuring. Please be noted that small error in calibration might causes large inaccurate in measurements. In order to achieve high accuracy, please try to use largest possible reference object. For example, please do not use A4 paper as reference object if you have A3 paper. From so many experiment we have done so far, the average accuracy is lie between (+)(-)2.5%.ON 3D-CameraMeasure is free with full features on android. We hope that this instrument can help you to save time and simplify your measuring works. If you have any comments, suggestions or questions, please feel free to contact us at [email protected]. Thank you!!

Smart App. I used it on my Nexus 7 gen2 2013 tablet; works great. It gives accurate measurement if caibrated properly following the instructions. If you fail getting accurate measurements, its user's fault for sure. Little difficult to understand and start with, as it is a new concept. Also some buttons block the screen. Otherwise, this app is very well built. I truly recommend this app.

Riz. Q. Feb 23, 2022     

As per my experience, the accuracy level is far beyond expectations. I wish i could share the image i saved after measuring a standard bed of 6ft, but app measurements shows 11.xx ft, which is wrong. Please fix the bug. I'm giving one star for it's attractive screen.

Raf. R. Nov 6, 2020     

Awesome application. Just the app that you'll need for surveying. Transparency is ther about variance of measurements is a plus. Manual included is detailed and easy to comprehend. More powers to the developer.

A. G. u. Jul 15, 2020     

Very nice and accurate. But please make the button backgrounds transparent and smaller, because they block most of the viewport.

Ami. B. Nov 1, 2018     

Idea is out of the box, however measurement is not accurate. For testing I took image of square tile and ref obj was credit card.. to my surprise app shows all sides with different measurements.. so funny .. who would like to use app with so poor results.. please improve results.

Joh. S. Jul 13, 2019     

This tool is amaizing, bu you have to use it for pre-projects which you don't need accurate measurements yet, you could save dollars alot. This tool can be accurate but difficult to use to be accurate, you still need some of those expensive tools to get easiness. I give 5 for the idea. Thanx...

JP. {. Mar 13, 2021     

It has potential but seems too buggy. Often cant delete lines or measurements. Cant find how to start a new measure... Just needs work on user interface

Car. J. Apr 8, 2019     

if they take the stuff out from the screen ,you be able to measure the area but every time you put the points in place or try to move them , the stuff is in the way and you press the wrong buttons

Cec. F. Jan 23, 2021     

Measurements are not accurate. It is not working. I place a box picture, and calibrate, the measure from the app is incorrect.

jam. p. Sep 26, 2018     

Completely useless. LENGTH varies with VERTICAL distance from the paper. Useless calibration option. DONT WASTE TIME ON THIS APP.

Sid. S. Nov 8, 2018     

It's just not that accurate. I guess it's hard on Android, every phone has a different camera and lens. Love the idea. Don't give up on it.

Adi. S. Sep 25, 2018     

Worst when measuring normal scale dimensions.. shows double the actual measurements.. the controls interrupt from gazing through the image and ads starts every now n then

Alu. V. Feb 3, 2019     

Grest free measuring app, useful app, But need some improve, phone's resolution(S8) effected to app display not match with an actual picture.

Ken. W. Mar 27, 2020     

Attempted many times to operate app as described...never got it to function in which the measurements recorded appeared to be the correct dimensions of feet/inches

Jam. S. Apr 24, 2019     

i was hoping for this to work like the apple feature but instead you need to provide a reference object and indicate the 4 corners of it.

Fad. G. f. Apr 10, 2019     

just learning but so far so good. a bit to learn as its a more comprehensiveve apk.

sup. s. Apr 23, 2019     

not accurate, however 3 stars for the cool graphics. a add on of my roof is 50 ft and this is reading 0.4 ft.

reh. m. Sep 27, 2019     

Very useful application. Almost precise in calcularion.

Tor. B. Oct 24, 2018     

No ft and inches, no override if you want to just enter your measurements, crashed x in 3 min

Sno. B. Apr 14, 2019     

very dumb app. heaps of ads. uninstall

:. D. Jul 11, 2020     

Tricky to learn but overall, a very good app to have.

Viv. V. Feb 16, 2019     

27.5 inches was 153 inches in the app.

A. G. u. Mar 14, 2019     

Working great... Please give more sample messurement... All OK... Thanks

Nic. L. Dec 26, 2020     

Doesn't work. Wildly off. I wish someone would make a measurement app worth a nickel.

A. G. u. Sep 27, 2018     

Couldn't get on with it. Too difficult to understand

Rau. B. Aug 28, 2019     

It is a pretty good tool to get mesures from a photo

Kha. H. Dec 31, 2019     

I can't save the pictures that I have operated your free app. Why?

Jef. F. Mar 18, 2019     

how am I supposed to measure anything when the whole screen is covered with buttons. Piece of junk
