This app has excellent potential but unfortunately I must give it only two stars because it is missing one of the most common shapes I use, a hollow rectangle, and it only calculates in metric units. I often do calculations in inches and feet also. if these features could be added to the app I would gladly give it five stars!

Thanks again for your feedback! The hollow rectangle shape and inch/feet unit support have now been added in the latest update. Your suggestions were incredibly helpful. I hope the new version works better for you!
