About this app

3D Measurement App / Plumb-bob is a laser level, a tape measure and a protractor, bundled together in the same app.
Thanks to 3D Measurement App / Plumb-bob, you can verify vertical and horizontal alignments, measure distances and measure angles.
This app is made for everyone, and can be particularely useful for interior designers, architects, and DIY enthusiasts.

3D Measurement App / Plumb-bob is an augmented reality (AR) app which displays a virtual frame on top of the camera image. This frame remains vertical regardless of the orientation of your device. The frame dimensions are displayed in real time.
There are multiple frame shapes that are suitable for a variety of mesurement use cases:
- height and width measurement,
- vertical or horizontal surface measurement,
- cubic or cylindrical volume measurement (paid version only),
- slope angle measurement with respect to the vertical,
- centering measurement,
- checking proportions by increasing the number of frame columns or rows.

When you take a picture, you can move the frame around, to measure any object which is visible on the screen. A magnifying glass allows you to make precise measurements.
When you're done with your measurements, you can save your work as a 3D scene in the app library. Then, you can later reopen it and measure other parts of the 3D scene.
You can also save your work as a standard picture in the phone gallery. This can be handy if you want to share your measurements inside an email, of if you want to insert your measurements in a document.
Another option is to send the 3D scene to another device running 3D Measurement App / Plumb-bob. The recipient of the 3D scene will be able to manipulate it on his own device, and measure any other part of the picture.

The app contains an online tutorial to give you the main advices to get started. Do not hesitate to send an email with your feedback, questions or requests for new features.

3D Measurement App / Plumb-bob is free but contains ads. If you find that this is annoying, there is a paid version which does not contain ads. And for a small price, you will also get extra features.

Millions of android users have been using this app. Give it a try and see by yourself how handy it could be. Happy measure with 3D Measurement App / Plumb-bob!

I did the quick tutorial, but that didn't explain the obviously inccurate results I'm getting. When keeping the phone upright, rotating it clockwise or counterclockwise results in the red "vertical" line (drawn over the image) tilting with respect to known vertical objects in the image. The red line tilts 5 to 10 degrees off of vertical when rotating the phone 30 degrees. Maybe some sort of calibration would help, but if so, that's not at all covered in the overly-simplistic tutorial.

Hello. Thank you for your review. Sometimes the internal sensor is not correctly configured and you may observe a deviation for some orientation. The app contains a calibration menu (open camera view, hamburger menu, second button). Look here for some instructions: https://www.youtube.com/watch?v=NICKguPvk3Q. We hope it helps. Best Regards.

Love this app. I've been using it for work and is great. I will be purchasing the add free version. My only issue or recommendation is to have an option to change the exposure of the camera because I use it outside and have issues with the sun in some cases. Overall great app.
