Move to measure - Flying Ruler app review

I can't vouch for the accuracy of flying ruler on older models of the iPhone but on my iPhone 6 it has been pretty much spot on every time I've used it. I must admit it did take me a couple of attempts to learn how to use it when I first started off but within a minute or two it really is child's play. So even the more butter fingered individuals out there should have very little difficulty getting to grips with it, if you'll excuse the terrible pun! If you are in the need for a tool like this, then you won't find a better app than this one.
