About this app

Partometer3D is camera app for area, perimeter, length and distance, height and width, ratio, circle parameters (radius, diameter), angles measurements. It can be used as a camera ruler or tape measure for accurate measurements on pictures and photos. This app allows user to make measurements in any defined direction and plane in 3D space.

The distances and object size can also be measured by Partometer App, but Partometer3D has no constrains on the camera position relative to the measured object.

The measurement plane / object plane don't have to be parallel to the camera plane.
It expands number of situations where application can be used. For example, big objects now can be measured by taking a picture from the side, objects and distances that are difficult to reach can be measured as well.

Partometer3D has the same application area as Partometer, but gives you more flexibility and power. Angle Mode / Protractor / Goniometer can be used for roof angle measurements. This data can be used in SolarMeter app for solar energy calculations.
It has following important and distinctive features:

- measure in any selected plane in 3D space
- Length, Angle, Area, Circle Modes
- add/delete any number of measurement/ruler lines
- values assigned to each ruler line
- measure objects in different directions
- save and share you measurement
- find object ratios, if you do not need absolute measurements
- compare object parts to each other
- use custom and predefined reference objects
- automatic reference object fine alignment using image processing
- reset reference object alignment by LONG TOUCH on auto alignment button

Partometer3D uses a phone/tablet camera and any available object with known size as a reference to perform measurement. To define the measurement plane a rectangular object (sheet of paper, credit card, custom object) is used. Image processing is used for automatic fine alignment with the reference object.

The App shows measurement results in different units: meters, millimeters, centimeters, feet, inches based on user settings. It also calculate dimensions of the object in relative units with respect to the reference object (ROL).

There is an option to make a picture and work with the still image instead of live camera view. Picture Load feature is also implemented to work with any picture from your photo gallery. Zoom View feature helps to align object boundaries accurately.

Partomter3D can be very useful if you need to measure bigger distances on the plane, where the simple ruler or tape is difficult to apply. All you need to do in this case is to place a rectangular object (credit card or sheet of paper) on the measurement plane,
make sure that the object of interest fits into the camera view and make measurements.

Thank you for your support.

Garbage. Don't waste your money. NOT a camera measurement tool!

More details would be helpful. What doesn't works for you? What do you mean under "not a camera measurement tool"? Please contact if you need any help and provide more details.

Read the description carefully-- this app does not work quite the way it is marketed This app DOES NOT allow you to measure in 3 dimensions. It is only a 2d measuring app. You lay down a known size reference object (a credit card or a piece of notebook paper for example) and and in your photo you use that to define the reference plane. You can then measure any 2 dimensional object in that plane only. After playing with the app, I understand why this limitation exists, but it should be made more clear before people buy. Some other issues... There is NO documentation-- the video here is it. Watch it before you buy. At least on my phone (an Lg G3), the UI is laggy and nearly unusable.. Even when it works, the UI is non-intuitive.

Thank you for your feedback. Please see see the measurement guide: It will be very much appreciated if you contact with more details about lags and issues on your device and other suggestions. It would help us to address them and improve usability. Thank you, VisTech.Projects Team.

A reasonably accurate app nearly crippled by some of the worst documentation ever written. The best first step to learning this app is to eliminate the Reference Object Line feature--go right to Preferences and drop it, it's clutter that serves no essential function--and to *fix* your reference object rectangle in place (long press the "W/H" area in the lower left side of the screen) or you run the risk of DESTROYING the measuring grid by inadvertently moving the corners of your reference plane when you start moving rulers around. And make sure the object that you're measuring is confined *exactly* in the measuring plane or the accuracy will drop dramatically. The limits inherent in this type of measuring system become apparent fairly soon, but still reasonably accurate, so 3 stars, 4 stars when those awful user guide pages are rewritten.
