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)

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,

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.

Wishing it was possible to rate zero stars

This app CONSTANTLY crashes on my brand new iPad 6th generation.. with the newest software there isn’t any excuses as to why this app is so buggy and crashes after every single measurement. I can’t even calculate one single square foot measurement without this app crashing. I even turned off all the extra automatics and displays in settings to help the system slow down but no help at all. Contacting apple to get a return ASAP.....
