Not accurate – i-Ruler Review

I have an iPhone X, so that may be part of the problem...but I used it to measure the long edge of a regular 8.5x11 piece of paper and the app gave me 10 inches. The whole point of a ruler is accuracy, or I’d eyeball an estimate. If this is an iPhone X problem and it’s fixed, I’d gladly change my review.
