Not Practical

App crashes when surface is detected, even after recent update. On iPhone 7 with latest software update. I work in a metals distribution warehouse and have to carry a 60’ tape measure with me constantly to tell the difference in-between 55’ and 60’ beams. When the app did work it was always at least 3’ to 6’ off, even after a perfect surface detection over a span of 50 to 60’. Up close it seems to work ok, but is off a good 1 to 2” sometimes. I still use it to get a general sense of sq footage when figuring steel plate for processing work comparing what I have on hand to work with, but practical accuracy is not there with really any VR app I have used yet, not just this one.

Initial impressions

I purchased this to see if my furniture would fit in a new house.

Maybe I’m missing something. In trying to measure the rooms in 3D everything overlapped and looked nothing like a room at all.

The room isn’t an exact box, when I moved around looking at the room on my screen it didn’t look like a dimension that humans could survive in.
Useless for my purpose. As a human.

The only use I see for this is maybe measuring a straight line, although I haven’t checked the accuracy on that yet.

Possibly my room was too dark. It seemed to have trouble recognizing a vertical plane. Maybe due to pictures on walls?

This is only my initial impression. Pure fury.
Then as I stood there yelling at my phone, a message popped up asking if I loved measure 3D!! Lol.

Good comedy timing I have to say!!

Possibly under absolute precise lighting conditions and planetary alignment this app may be great.

I’ll persevere.

Any tips would be welcome.
Or a refund (in human currency. Not Zeta Reticulan)

Please watch video tutorials on our facebook page.

The first and important step is finding a wall or floor correctly. The accuracy is mostly depending on this step. Point the camera at the floor or wall and wait a moment or move the device slowly. When a white grid plane appears on the screen, make sure it is about 50 cm or 20 inches. If it does not match the size, try moving the camera slowly until a new plane is recognized. If it has difficulty to find a floor/wall, try to move closer to the floor or wall.
If a good virtual plane is found, the measurement error should be less than 1%.
Once you are familiar with this step, it will take only a few seconds to do it,

If you are not satisfied, you may ask Apple for your money back.

Good journal for my kids height

I figured out how to measure exactly in about 10 minutes. But once you know how to measure, this is very good app with many useful tools. My favorite is person height tool which I am using to keep track of my sons’ height.
