Nice interface but quirky and hard to use with unreliable and inaccurate measurements. Repeatedly scanning the same object dimension will yield different measurements each time. Trying to measure a long dimension in segments is particularly difficult; sometimes the app picks up at the desired spot and continues, other times it refuses and wants to “triangulate” instead. The interface also randomly switches a virtual tape measure on and off. It’s a great idea that would have serious utility and value IF it worked. But this version is not ready for prime time and definitely not worth the price. Save your 99 cents.
