The key seems to be to take your time, make sure you have a good direct angle on what you are measuring. The biggest key is to be sure you have laid out an accurate starting point and termination point, avoid taking curvature etc into the measurement. This is an app best used with solid angle items, like boxed packages for mailing, picture framing etc. avoid curved or funky shaped items. Those would be better measured with a soft measuring tape, like the ones used to measure your waist, etc. Kind of bare-bones app but it’s free. The more feature-laden apps out there are also subscription based and can cost up to $100 a year to use. Well worth it for the professional who would use it many times a day for mission critical stuff, but if you only need an app to take an occasional measurement here and there this is a perfectly adequate app for most instances.

Only reviewing /commenting on the use of the surface level feature, I use often and unsure how accurate it is which leads to question it’s usefulness on iPhones since iPhone’s camera bumps have increased in size varies between models. To be clear, I am speaking of the Level feature when laying a device flat on its back to see how level a table is for example. It may require additional work if it’s not done already but Apple should account for the discrepancy that exists on different iPhones models considering the camera bumps vary in size. Then again people have cases on their phone so unsure if this is a problem that can be solved leading to questionable usefulness of this feature.

Absolutely love this app! It’s awesome in a pinch! But I’ve always thought how cool would it be to give XY and Z coordinates from point to point. Say if I measure something on the X and Y axis it would show length and width and Delta Z would be equal to zero, but if I was measuring in all three planes it would give me dimensions from point to point for each. Also, it would be fantastic to be able to switch between length units like decimal inches, fractional inches, feet and fraction fractional inches (architectural), as well as meters, centimeters, millimeters, etc. I understand that this app and the camera and lighter scanner are limited by a tolerance of a quarter of an inch if that! That’s just my two cents, it’s been a minute since this app has had an update!

I bought a stand with holes for dog food bowls; then I lost one of the bowls while traveling. The seller didn’t sell replacement bowls, and the holes turned out to be of an unusual size, for which I couldn’t find any bowls online that wouldn’t stand too high or fall through. After measuring the remaining bowl, I went to the store and used the Measure app on bowls and containers until I found one that seemed the right size. When I took the container home it fit perfectly! The only reason I gave Measure 4/5 stars is I had a little trouble figuring out how to use it. Only took me about 1 minute right there in the store though.
