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.
