Absolutely the BEST!

The ability to have all this precise spatial and positional information overlaid on the cameras on my iPad Mini or iPhone is awesome. I use it to lay out foundations, navigate the old fashioned way with gps off, calculate distances using landmarks of known height, or the reverse, just for kicks. I have reviewed maybe half a dozen apps out of several hundred I have purchased. This one was certainly worth the time to heap praises upon it! Awesome app! Well done!
