***TOP 100 Utility App in over 30 Countries!!!***

Simply aim your iPhone/iPad to any object in your surroundings, and Smart Measure displays the distance towards that object on top of the camera image.

Find out how far it is towards that boat at the other side of the lake. Measure how tall buildings are. Use the app as a hunting or range-finder. Measure your friend's height. The possibilities are endless!

How does it work? Smart Measure uses the height of the camera lens and its tilt angle to calculate the distance to the object. A comprehensive animated tutorial on how to use Smart Measure is included.

Where are the instructions?

I have a degree in physics and advanced mathematics, and I don’t know what I am supposed to do to use the app. It tells me my office wall is over 30 feet away, I see a frame around the person in the example, but all I ever see on my phone is a grid that shrinks in the distance like a Star Wars introduction. There is a slider on the left, I have no clue as to what that is supposed to do or what it is telling me. Could we please have some instructions? The sample video shows somebody aiming the camera at a tree, but no instructions on how to read what I am looking at.

Hello Bob, no trig classes in school? As stated in the description, the app works by trigonometry. Did you read the full description and instructions?

Measures OK

Seems to work OK. Uses vanishing line technique but fails when the above the center of the screen. Example: My TV is 15 feet from me and four feet up on the wall. The program vanishing point grid won’t reach the bottom of the screen and says it it over 300 feet away. I think I’ll read the instructions again.

Developer Response ,

Thank you for the feedback Rbriver! The app works by trigonometry. If you have your height measurement (height of the camera lens) adjusted correctly + calibration, the app will work as described.

Seems to work okay

It works for me, and I think I'm using it like I should. I'll give it the five stars because t is the only one I've found that woks on my old iPad 4th gen

Thank you for your feedback MeBec. Yes, that is correct! Smart Measure is not based on AR Kit, therefore all devices can use it:)
