Not accurate

Can be used as an estimated guide

I like it

it takes a few tries to get comfortable using it but it does it's job and works well. I size things and then send them to my vendors to size picture frames for me. the zoom feature is cool too.

Not perfect but great for a quick estimate

Very fast app for quick estimates of items about 3-6 feet long. I use this to quickly estimate doorway sizes, floor sizes, rough window sizes. Its off by 1" but for anything needing an estimate it saves time if you don't carry a ruler

You snap a photo with an object of known length in the frame (like a piece of paper which is 11" long). You slide a few bars on the photo and you have your estimate. Does what it says
