Just got duped!!!
Measurements are completely inaccurate. Dont waste your money like I did. It amazes me how there is no consumer protection for fraud on the app store. This developer should have to refund all the people he lied to. At least offer it for free to get feedback while developing then it would be understandable. If I knew I had to pay to be a beta tester I would never have purchased this crap!!!!! Arghhh!!! Beware... Free trial works decently but purchased version which supposedly allows you to measure longer distances is not accurate at all.
